Pro tips: Cleaning Your Bike

   Keeping your drive train clean is the key to good performance and long component life. It is also a time consuming pain in the ass. The easiest way to do this is to blast the crap out of your bike with a power washer. This is ill advised.


Bad!

   High pressure can force the water and dirt into places that it may not belong. In the frame, in the bearings, all places that should stay dry. When I'm washing my bike, I like to use a garden hose and kitchen brush. These brushes work great, are pretty cheap, especially if you get them at IKEA like me.

50 cents each

    They're good for a many uses on the frame, or a few on the greasy drivetrain. The brissles won't scratch up your paint and are great at loosening dirt and gunk. Once they're black, they are not really removing gunk as much as moving it around, so just toss them in the trash.

The life of a brush

   So go get yourselves some cheap brushes and give your bike the cleaning it deserves!

Winter Park Race #4 Report

   Another race in the books at Winter Park. This one was particularly painful, and the results reflect that. This race had it all:
  • Denial: "This can't be happening, I will catch them on the next descent."
  • Anger: "I'm throwing my bike into a river, then pissing in that river."
  • Bargaining: "Just let me get through this race and I'll never eat another Ande's mint."
  • Depression: "I'm going to stop here and just lay down and die."
  • Acceptance: "Next race will be better, it can't be worse."

   My goal to not finish last has been busted twice, but I feel like this time I put in a much stronger effort. Let's talk about the course. Here's the profile I used to map climb distances:

Epic Point to Point profile

   You want climbing? We got climbing. This had around 4000 feet of climbing in 25 miles. The tricky thing is the combination of climbing and 2+ hours in the saddle. What does that get you? 

Results

   It gets you last! I was in 6th for a while, but got caught on one of the longer hills near the middle by two guys right in a row. After that I was never able to catch up to either of them. Compounding things, me rear brake went south at the top of the first climb. The brake went south because (I think) of some bad seals. It was leaking everywhere. That is no excuse to ride poorly, but it sure doesn't help on the descents to only have a front brake.

General feel of the race

   Strangely, I started feeling pretty good about 2/3 through the race, and was able to make up some time. I think with that kind of energy through the whole race I would have stood a better change of maintaining 6th. 
   Like all races, the sting of both exhaustion and loss started to ebb immediately after finishing. I am already amped for the next one!

Friday WTF: How Soft is Aluminum?

   Today is a two-fer. Ever wonder how soft aluminum is? Well, here's two examples why you have to treat alum with a little care. 

Exhibit 1 - Shoe rub has worn these aluminum crank arms severely! Apply a little too much power and you risk snapping one off.


Exhibit 2 - Cable rub can do a lot of damage in a short period. This is why it's a good idea to protect your frame with some protective tape.


Exhibit 3 - Exhibit as an exhibit.

   Some bikes and teams of note:

Kemo Bikes KE-R8 5KS
  • The team Cofidis Look 695 Aero is a bad ass looking bike, with some color styling harking back to their roots: 
Look KG 171

2014 Tour de France 695
  • Team Lampre on the Meridas marks that bike manufacturers first foray into pro racing. Which is great since they're a huge company (for example, they own Specialized) About time they manned up and sponsored a team!
  • Worth mentioning that Cannondale's bikes are pretty off the shelf THAT'S RIGHT THEIR BIKES ARE THAT AWESOME
  • Nearly half the teams (10) are using Shimano Dura-Ace Di2 electronic shifters. Neat to see this technology in the big races. 

   All very cool things from the top teams. Lastly, here's some awesome footage of what it's like to be in the pack at The Tour:

Making the Baby Cage less 'Prison-y'

   Calvin has been getting a lot of use out of the baby cage play are that we set up for him. I had thought it would be fun to incorporate some play things in it, and finally got around to setting one up: a little pipe to drop toys through. Here he is with the two pieces of the barrier taken apart:

Max supervising

   I started with some 4" black plastic pipe. The two angles I hat to cut were real weird. I held it up and kind of roughly drew a line where I should cut it.

Precise measuring

   After cutting it, I traced the shape onto the top of the wood and cut it out with a scroll saw:

Hole traces and pilot drilled

  Once I had everything in place, I used some pipe strap and a couple screws to hold the pipe in place. It worked well because by tightening the screws further in, it really snugged up the pipe.

All in place

   All that was left was for Calvin to try it out. It took him a bit to understand why toys were hitting his feet was happening because things fall through very fast. If I were going to redo it, I think I would angle the pipe so that they came out a bit to the side of the top hole. 

Physics at work

Friday WTF: Why Seat Post Insertion Limits are Important

   Seat posts have these little marks on them to remind you not to pull your seat post out too far. They usually have a line, or an arrow or something clear. 

Minimum insertion line

   What is the danger, you ask? Well have a look here:

Snap!

Crackle!

Pop!

   These cracks are the result of the seat post not fully inserted in the frame. The real danger is not in noticing your frame is cracking, it is in the frame failing entirely:

Disaster!

   The results of this kind of failure are too graphic to put on this family friendly blog, so please mind your seat post insertion marks.

Tour de France Special: What is that Yellow Car?

   If you've been watching the Tour, you've been on the edge of your seat with crashes, victories, heartbreak and ... yellow cars?

I spy with my little eye something yellow

   What the heck is going on with all these cars anyway? Well, most are the support cars for each team. They have coaches, mechanics, food, EPO, tiny motors, the usual bike stuff. There is one special car though - the Rudolph of support cars: The Mavic Neutral Support car.

Mavic Saab

   The neutral support car is there for anyone and everyone. They provide wheels and even whole bikes for riders who have a problem and have become separated from their team car. This is especially important when several riders on a breakaway are far from the rest of the pack.
   In addition to the car, they often have a neutral support motorcycle carrying wheels.

Motorcycle and car

   The set up on the motorcycles is pretty cool:

Wheel carriers

   For the loaner bikes, they usually use Cannondale CAAD10's, since they're pretty cheap and still can get the job done. They're marked same as the cars.

Mavic CAAD10

   And here is Jens Voigt on a junior bike, descending until he can get back on his regular bike.


   Please note the toe clips, and undersized frame. Is there anything this guy can't do? Read the full story of that adventure here
