A helping hand




I can't tell you how many times I've been interrupted while in the middle of taping bars.  The phone rings or I forget to grab the electrical tape.  Or, worst of all, trying to cut the end when it slips out of your hand and flops around and around, enravelling the work you are about to finish.  Then a few weeks ago I found an answer.  I was hanging out in my buddies garage and saw him grab a spanner wrench and use it to pinch the bar and hold his tape in place.  Where has this been all my life?  Now I use this trick every time I need to tape handlebars and I'm passing it on to you.

This is an indstry of tricks.



Bicycle mechanics work in an industry of tricks. Every little trick saves time and every little bit of time adds up to more services done. This is important in the shop or at a race.




This is a little trick I came up with for the Park BBT-10. 




You start by grinding both sides down evenly until the tool is 2mm wide.





Then you grind the top edge until it is square.






You still use the tool in the same way. But when you would normaly reach for a flat head screwdriver, you just turn the tool on its side and use it to flip up the plastick retention tab.




And voila! Just a little trick that saves you one step.

A whirlwind week of Beers, Bikes, and a little VooDoo


Last weekend Miranda and I flew to Portland for this year's Park Tool Summit. We flew in a couple days early to take in some of the sights. Portlanders do not mess around. Maple doughnuts come with bacon on top! What I thought would be a standard cup of coffee, ended up being some of the best coffee I have ever had. And Miranda had Pho soup she loved so much that she went back the next day for more. 




Here she is at VooDoo Doughnuts!




Everything is better with bacon.




Delicious and nutritious!

After two days of exploring, it was time to get down to business. I woke up early Monday to check in and get my schedule. First was Park Tools with a comprehensive class on proper installation of tubular tires and a new way of charting spoke tension. Then we had a short brake and it was off to Fox to talk about the new CTD platform. I was super excited for this class, because of my work with Nationwide Veloworks. Everyone on the team is on a CTD and I was able to find the answer to some of our recent problems. I stayed after class to get a few more tips and almost missed lunch. After a quick bite, I rushed to Mavic where we discussed the new braking surface and how to service their new freehub. I also learned the best truing techniques for their carbon cross spoke wheels. After 9 hours in the classroom, I ran up stairs to grab Miranda and we were on our way to the party. Right away we ran into my buddy Federico from the Slippery Pig Bike Shop in Phoenix, AZ. Talking to mechanics from all over the world and drinking free beer make for a great party. It's amazing to hear the different issues that come up for mechanics all over the world, even though we basically do the same job. The vendors at the event were giving away tons of cool swag. I was lucky enough to win two Crane Creek 110 headsets!




Day two started off with Shimano's new 9000 series Dura Ace. There were so many changes to the system, I was stoked about all the improvements. We must have spent the first hour and a half on the front derailer set up alone. Next on the list was SRAM where we learned about the new Red Groupo. We also went over a basic rebuild of a Rock Shox Reeba. I was a little disappointed that they didn't talk about the new 1/11 since that was the reason I signed up for the class in the first place. After SRAM I got a little food,  then finished up the Summit with Crane Creek. We learned about rebuilding a Double Barrel shock and went over a new system of proper head set selection. It is truly impressive how many head set combinations are out there these days. The next morning, Miranda and I got up at 3:00am to fly home.




As soon as we landed I was on my way to work. The first thing I saw when I walked through the door was one of the Nationwide/Veloworx bikes having an issue with it's Fox CTD. It felt great to know exactly how to fix it and be able show off my new skills. I spent the afternoon prepping a few bikes for the upcoming 24hrs in the Old Pueblo. I had two days to sleep in my own bed and it was off to the Old Pueblo!




For this race I wasn't working with Nationwide. I was there to help my good friend and boss, Kaolin Cummens, with his attempt at Solo Single Speed. And another good friend of mine, Kevin Grunion, who was going for Two Man.




The race started off without a hitch. Kaolin ran hard and the bike hand-off was perfect. Kaolin was in the lead for the first two laps. We did a quick gear change on the third lap, switching to one tooth easier in an effort to accommodate the strong head wind. We knew we had a problem on the forth lap when Kaolin came in 10 minutes late. Kevin came through the pits on his lap and told us he saw Kaolin on course messing with his seat. I quickly got our spare post and seat ready for when he came in. We waited and waited and finally he rolled through. Two weeks prior Kaolin had a bad crash in the Single Speed AZ Race where he hyper-extended his ankle. After extensive rehab he was cleared to race again, but the injury still affected him enough to take him out of the race. Once we decided it would be best for Kaolin not to go on, all of my efforts were focused on Kevin and his teammate. Going into the night, Kevin's team was in 20th place. But they rode hard and by morning they were in 12th. They managed a very solid finish in 10th place!  Here's Kevin on his last lap.

Today I want to show all of you one of my favorite tools, the Park BTS-1 bottom bracket, tapping and facing tool.  The reason it is such an important part of proper bike assembly is because it makes both sides of your bottom bracket perfectly parallel.  Anytime you have two barrings running in parallel, they need to be on the same plane or they will be working against etch other.  If this happens, they will either wear out prematurely or create drag, which no one wants.

Step One is to put your bike in a work stand, of course.  It's important to have a stable platform to work with.

Step Two is to identify the left and right sides of the tool which is designated by a LH and RH on the tap.  Now you would think that the left handed thread would go on the left side, but it is the opposite.

Step Three is to cover the cutting tool with fluid and flood the bottom bracket shell.  I like to use Cris King cutting oil.  Don't be worried about putting on too much, cutting dies are super expensive and the oil is cheep.  So lube it up good.

Step Four.  Carefully start threading the tap into the bottom bracket shell by a few threads.  Once both taps are started, turn them at the same time in the appropriate direction until you feel some resistance.  From this point on you should turn them no more then a half turn, then back a quarter to clear out the threads.  Remember to keep adding cutting fluid every full rotation or so.  Once you have the tool started a few full turns on both sides you can alternate from side to side.  Keep going until the tap is recessed into the shell.




Step Five.  Now we can start facing.  Pull the handle completely out of bottom bracket leaving the tap tool inside.  The tap will now act as a guide for the facing mill.  Install the facing mill cutter on the handle, then reinsert the handle into the taps.  Add fluid to the cutter, then apply steady pressure to the center of both handles and rotate only in a clockwise direction.  If you turn counter-clockwise it will dull the tool.  Only apply enough pressure to get a good 360 cut, if you press too hard you will gouge the shell.  A little chattering is ok, its only cosmetic and won't affect the function.  Repeat this step on the other side.

  

At first, you will just be removing paint.


 Almost there, just a little more.



Final Step.  Remove the tool from both sides of the frame at the same time, then clean off the tool and re-oil before storage.  Now you can clean out the frame and wipe it down. It's important to remove all remaining metal.  The final touch is to wipe a little grease on the new threads with you finger.

I hope you enjoyed seeing how this tool works, it's always fun for me to use it.

Jan 12, 2013.  The first race in the New Year.  Twelve hours of Papago is a fun event held in an odd location under an over pass in downtown Tempe, AZ.  It looked like the kind of place you would dump a body or score some drugs.  But on this day it was filled with hundreds of mountain bikers getting ready for a 12 hour endurance race.





On this fine morning, Kaolin and I were up at 4:00 am to get to the venue. He was racing on a coed quad team for Nationwide and I, of course, was their mechanic.  I couldn't believe how cold it was when we got there.  Twenty-four degrees.  If you're not from southern Arizona, you're probably laughing right now.  But 24 degrees is frigid by Arizona standards.





While we were setting up for the race, a rider who was warming up rode by our tent when his freehub locked up.  This wasn't someone that was on our team and we actually had never even met him before.  But Kaolin and I dropped what we were doing and rebuilt his freehub on the spot.  We also decided to remove a spacer that was improperly installed in his cassette and re tune the bike.  This one of my favorite things about endurance racing.  Everyone helps one another, even if the person you help might end up beating you.




As the day went on, it was your typical AZ 12 hour race, except for the cold weather.  The day consisted of many dirty chains and a few minor tweaks.  We were lucky enough to have our pit right at the finish line.  It was so much fun listening to music and watching the racers run through the timing tent.





I have been to thousands of mountain bike races in my life and seen some spectacular finishes, but nothing compared to the last lap of the Open Quad.  Nationwide and Bicycle Haus had been battling it out all day and it came down to the final lap.  Haus was in the lead buy just a few minutes and everyone was watching in the change out area when they both came in at almost the same time.  Rick Bucker from Haus made the handover first with Matt Barolt right on his heels.  The entire croud was watching as they sprinted by us and back onto the course.  Rick is a Cat 3 road racer and a monster at the crits while Matt is an ex-desert moto cross racer who is one of the best technical riders I have ever seen.  No one knew who would prevail; the big motor or the skilled handler.  Everyone was gathered around the finish line staring into the darkness looking for a hint of one of their lights, when all of a sudden a single light appeared.  It was Matt and Nationwide had taken the lead from Bike Haus!

I tried to take pictures to share with you, but nothing turned out.  Here is how we did.

Nationwide Duo One - Duo 12 Hour - 3rd Place
Nationwide/Veloworx LABBW - Duo 12 Hour - 6th Place
Nationwide SHNT - Quad 12 Hour - 1st
Nationwide/Veloworx Do-Nut-Count Us Out - Quad 12 Hour - 13th
Leah McCabe - Solo Womens - 1st
Nationwide - Quad CoEd 12 Hour - 2nd
