How To - Protect your parts washer tank from internal corrosion

Here's a quick and cheap way to protect your parts washer tank from corroding.  I've noticed the cheaper tanks require a water based solvent which are almost always acidic so here is an easy way to protect your tank from corrosive solvents.

Step one - Attach some copper wire to some scrap aluminum by using a steel bolt.  Here I used a scrap piece of an old Stan's rim.  I sanded it down a little so that the bare aluminum could be in contact with the fluid in my tank.  In my case I use about 1 gallon of purple power to about 12 gallons of water.  The acidity will only affect the consumption rate of the aluminum, the tank will be safe as long as you install a new piece of aluminum when the old piece gets consumed.

Step two - Attach the other end of that wire directly to the tank (inside or out, doesn't matter).

                     Step 3 - Submerge scrap aluminum inside the tank

That's it, you're done.  The most important part is that the aluminum is electrically continuous with the steel in the tank and that the aluminum is placed inside the fluid.

Here you can see I measured the results using a CuCuSO4 reference cell.  My native steel potential is about -593mV.  Minimum protection is -693mV.  With the aluminum anode I have achieved -1136mV which proves that the steel is easily being protected by the aluminum.

Native steel potential of the tank and reference cell for testing.  This was taken before the aluminum was placed in the tank.

Now protected at -1136mV.  This is after the aluminum was submerged in the tank.  Note: this only works if the aluminum is somehow connected to the tank.

All done

2016 South Carolina Reunion!!

Well it's been a while since I did anything here other than post a few brief comments on some older posts.  So I thought I would make this post a good one :-)
I've had some pretty awesome adventures for the last 2 years and have been lucky enough to have the chance to do some pretty fun and unique cycling trips.  I get quite a bit of time to do whatever I want during the spring months so I figured I would do something extra special for 2016.
Yes folks is a South Carolina reunion!  At your favourite of venues, The Palace.  Not to say that I will never do this again but it will not be a yearly thing.  There are too many other awesome trips I want to do.  So please try to take time out of your busy schedule to meet me down there to get in some riding cause who knows when this opportunity will come again.  I will be bringing a mountain bike and a road bike.
You should all know the drill and the house by now.  The only difference is that this year I am booking the weeks Monday-Monday.  Arrive any time on the Monday of your week and leave any time the following Monday.

Availability for 2016 (updated Nov 29, 2015)

Ritchey Foam Grips

'Nother little part came in at the bike shop.  Picked up my Ritchey foam grips this morning.  Mostly I was excited to get these since I needed to cut my old grips off to be able to cut my handle bars narrower.  The bars were a very wide 29.5" which while fun in the fast stuff were very cumbersome in the twisties.
I cut an inch off each side so now she sits at 27.5" which if I remember correctly is what I normally run.  The Ritchey grips are so much nicer.  The Lizard Skins were extremely hard on the hands.  Put them on the scale and was pretty obvious why, they are 1/2 the weight of the Ritcheys!  I was really surprised about this but oh well, I will have to save weight elsewhere.

The weight of the Lizard Skins grips plus the inch of bar I cut off (which had aluminum inserts in the ends) were still lighter than the Ritchey grips :'-(

Daang you heavy

Looking clean.

Next on the chopping block, these boat anchors.  Can't wait to get these off the bike!

Bought this horrible cage to hold me over until I can find something nice ;-)

So I'll just keep plugging away on this beast.  I think she still has about 4lbs to lose.  Gonna be a challenge.

Ze Germans are coming!

Went and bought myself a little treat the other day.  It was somewhat forced *twist my arm* because the saddle on my new-ish mountain bike managed to expire.  No idea how really, wasn't too concerned about it as it was pretty uncomfortable.  Not to mention I need to put this new bike on a diet so was not upset at all to see the old saddle go.
Soooo what did I get?  Thought I would try out the new Tune Komm-vor saddle.  Chose this model for a few reason.  It's not the lightest of the light saddles but it does seem to be a little more durable maybe, and is rumoured to be quite comfortable.
Post man came today.  Saddle was well packaged and initial cosmetic impressions were very good.  You never really know what you're going to get with this handmade stuff but everything looks pretty straight and true with a fairly high grade finish.  No complaints here.

Chucked it on the scale.

Came out at a respectable 91 grams.  About half the weight of the Syncros saddle that came off the bike.

Broken rails

Initial sit-down was positive but I'll get back to ya'll when I get some mileage on it.  My main problem with the Syncros was that there was zero flex in the shell, it was as hard as a rock.  In comparison the Tune seems quite soft.  But time will tell.  Flying back to Ontario this weekend from BC for a friendly 5man team at the Summer Solstice 24 hour.  Should get some good time on it then.

The best XC disc brake pads

Can disc brake pads really make a big difference with your braking? 
The answer is yes, brake pads can make a huge difference in the performance of your disc brakes.

So who makes the best pad?  And why are they so good?
I have tried many different pad companies, many different rotors, and many different brake systems.  All 3 of these components play a crucial role in brake performance and a weakness on any one of the 3 can make a good brake perform poorly.

The best brake pad for your XC bike, drum roll please, is the Jagwire Mountain Pro Semi-metallic.

What is wrong with other pads?
The main issue I have found with OE and other aftermarket pads is a nasty thing called glazing.  Glazing is when you build up a super hard conglomerate of brake dust and crud on the surface of the brake pad.  This makes the pad very smooth and rock hard.  This makes your brakes squeal like a banshee, gives poor modulation, and can send paralysing vibrations through the entire bike. The worst examples can be found in Avid and SRAM OE brake pads which become un-useable after a period of time.  I have had customers whose Avid pads have glazed over in just a few rides.  Regardless of whether you brake them in properly, brake too much, or get them too hot, brake pads should never get so bad as to be thrown out a few weeks into their service life.
I have tried lots of different things to deal with glazing.  I have sanded and degreased rotors, installed brand new rotors, installed different types of rotors, and I have physically sanded the glazing off of brake pads.  All of these were very temporary solutions or accomplished nothing at all.  I had narrowed it down to the brake pad construction and compound.  Something needed to be done.
Enter Jagwire!  I have found that Jagwire pads NEVER build up a glazing.  They are a smart mix of different composites and considered a semi metallic.  They give you the best compromise of everything really.  They grab hard but have a decently long service life.  They are inexpensive and lightweight.
Whether it be Shimano, Avid, Formula, Hayes, I have always found the Jagwire pads to be an improvement over OE compounds.
For the past 4 years I have been converting riders who seem ready to give up on their current brakes due to poor performance. 

-no glazing
-no squealing
-consistent performance in most weather
-light weight
-performance doesn't deteriorate as they wear down

-only last about 3/4 as long as a full metallic

Semi metallic construction with super light weight aluminum backing plates.  Yummy

So go out and buy a set of these for your disc brakes and relieve yourself of the crappiness of OE pads.

How-To: Service your headset

The headset of your bicycle is one of those components that is frequently overlooked.  Although headsets don’t require the regular maintenance high wear items like your drivetrain do, it is still important to keep the bearings in good shape and it's very important that it is properly adjusted.

There are a few different types of headsets but fundamentally they function the same.  Today we are dealing with a very common type of headset which goes by a few different names.  I refer to these as “zero stack”, they can also be called “semi-integrated” or “internal”.

Here are the 3 main types of headset.
Integrated – often found on lower end bicycles these bearings run directly against the head tube of the frame.  Therefor the bearing races cannot be replaced.

Zero Stack – probably the most common headset on most of todays modern bicycles.  The head tube is designed to hold a cartridge bearing inside of it.  This mostly hides the bearing from sight.  The bearing is easy to replace if it gets worn out or damaged.

Conventional – Common up until about 10 years ago, conventional headsets are a self contained unit.  Often “loose ball” style bearings complete with bearing races.  This headset is pressed partially into the headtube but most of the headset remains visible.

Zero stack is really the most sensible headset option.  There are a few major advantages to this system.
-you can replace the bearing very easily, and cheaply.
-the headset is very low profile which allows you to run your stem closer to your frame.  This means handlebars can be lower in height which allows you to tailor the fit of your bike better.
-since the bearing is low profile, head tubes can be made larger which increases frame stiffness and steering response.

This How-To will address headset removal, cleaning, installation, and adjustment.  Headsets can also be a common source for creaks and squeaks so this service will reduce the likelyhood of those as well.

Tools required (left to right):
1 – rag for cleaning
2 – Allen keys
3 – all purpose grease
* - optional, makes life easier.
*4 – long zip tie
*5 – side cutters

 Step 1
A bike stand always makes life easier.  With your bike secured in the stand, remove the front wheel to take some weight off the front end.
Step 2
Loosen the stem pinch bolts.
Step 3
Remove the top cap.  At this point you must hold onto your fork or it could drop unexpectedly out of your bike and onto the ground.
Step 4
Determine whether your fork steerer tube is properly adjusted.  The deal here is that your fork steerer MUST NOT touch your top cap.  The reason for this is that the top cap adjusts the load on the headset bearing.  If the steerer tube of the fork is resting against the top cap then the headset cannot be tightened any further.

In the illustration below you can see that when you tighten the top cap it squeezes the bearing of the headset.  If your fork steerer is too long you won’t be able to tighten the headset enough.  You can adjust the length of the steerer either by adding spacers or by cutting the steerer tube shorter.
If the steerer is too short then the top pinch bolt on your stem won’t tighten the stem onto the steerer tube of the fork and you could crack your stem.  The top pinch bolt of your stem needs to clamp down onto steerer for the most secure fit.

Step 5
Begin disassembling your headset.  Start by removing your stem.

Step 6
As you are removing various bits of your headset it is a very good idea to set them aside in the order that you are taking them off the bike.  That way you know how it all goes back together.
With your spacers and headset dust shield removed now you can remove the small taper ring.  Sometimes you have to tap on the top of your fork steerer in order to knock it free.  Use either your hand or a rubber mallet.

Step 7
Now you can use that long zip tie to hold the fork in place.  That way you don’t have to remove the front brake.

Step 8
Now we are getting into the real meat ‘n potatoes of this How-To.  You can remove the top headset cartridge bearing.  You should be able to just pull  it out with your fingers.  Might have to wiggle it around a little.

Step 9
Remove the bottom bearing much like you did with the top bearing.  The bottom bearing is much more exposed to dirt and water so it is very likely that this bearing will be in worse shape than the top bearing.  It may also be a different size since many modern bikes/forks come with tapered head/steerer tubes now.
The bottom bearing sometimes comes out with the fork as well.  So you might see it on the base of the steerer tube.

Step 10
Set everything aside.  Here you can see that I have kept it all in order.

Step 11
With everything apart, now is the time to clean everything up.  Anytime you have moving parts interacting with each other you need to have very clean mating surfaces.  This reduces the risk of contamination and any number of undesirable crunchy, clicking noises when stuff does start moving or is stressed.

Step 12
Roll each bearing in your fingers and make sure they move freely.  If you want to be a superstar then some bearings can be flushed out and re-greased.  Check out “How to clean cartridge bearings” to get the jist of this process.
If the bearings are notchy or rough then chances are it is time to replace that sucker.  The good news is that they only cost about $30.  The beauty of cartridge bearings.

Step 13
Now that everything is cleaned up and functioning well you can start putting it all back together.  It is a very good idea to have a film of grease on any mating surface of a bearing.  Helps to reduce creaks big time.  You can use your all purpose grease for this job.  Take some grease and roll the bearing around in your fingers giving every surface a thorough coat.

Step 14
Re-install the bottom bearing.  Look to see if there are any tapered surfaces on the bearing.  If there are make sure they are orientated correctly.  Give them a test fit, it will be obvious which way it goes if you forgot to keep track during disassembly.
Slide the bottom bearing onto the fork steerer.

Step 15
Re-install the top bearing.  Make sure it is seated squarely in the frame.  You just push it in with your fingers.

Step 16
Install the fork back into the head tube of the bicycle.  Make sure that when you are pushing the steerer through that it doesn’t knock the top bearing out onto the ground or you’ll have to clean/grease it all over again.
Also when you install the fork make sure that all the cable and hoses for your brakes and shifters are correctly positioned.

Step 17
Make sure the fork is seated in the frame of the bicycle.  Check for any weird looking gaps at the bottom bearing.  Also double check that all the shift and brake housing and hoses are orientated correctly.

Step 18
Install all the little spacers and rings in the order you removed them.  Don’t worry if the small taper ring doesn’t push down all the way.  When you tighten everything down it will push into place.  You can grease the taper ring as well.

Step 19
Slide your stem back on and loosely install the top cap.

Adjust your headset
Step 20

Now you can begin the process of actually adjusting your headset properly.  When you know the process this is a job that takes about 60 seconds.
Remove your bike from the stand and put your front wheel back on.  Right now your stem and front wheel should move independently of each other because the stem pinch bolts are still loose.  This is important.
We learned before that when you tighten the top cap, and your stem bolts are loose, it will tighten the load on the headset.  Since we just had everything apart I suggest that you tighten the top cap to about a 6 out of 10 (10N-m approx) so that everything gets squished together nice and square.  Then loosen the top cap right off again and go from there.
You want enough load on the bearing that the bars spin freely but so the bearing doesn’t have play.  Adjust the bearing pre-load via the top cap to where you think it is a good compromise.  You can test the bearing buy snugging down one of the stem pinch bolts.  Turn the handlebars side to side through their full range of motion.  If the bearing feels rough then it is too tight.
To test if the bearing is too loose you can squeeze the front brake lever and rock the bike back and forth (front to back).  Place your hand between the bearing and the head tube of the frame to detect any knocking of the bearing.
Keep fine tuning that sucker so that there is no play in the bearing but the bars are still buttery smooth when you turn them.

Step 21
Now that the bearing preload has been properly adjusted you can make sure your stem is aligned with your front wheel.  Pretty much just eye-ball it and tighten the stem pinch bolts to secure it in place.  If later you find that it is actually crooked, or you have a crash and they turn, you can always loosen the stem pinch bolts and straighten the stem without affecting the preload on the headset bearing because you are not adjusting the top cap.

That’s it, you’re all done!  Now you can turn like a boss and your bike should run a little quieter.
