This is part 1 of a multi-part Garage Files blog about rebuilding a friends Cannondale.
A few years ago I managed to convince a friend that mountain biking was a fun pass time. He set out with me in tow to look at new bikes and bought a 2013 Cannondale Trail 4 29er. Its a well spec'd bike for the price and he put 3 seasons of riding on it since, shredding singletrack at Turkey Point, towing his kids around in a trailer and a trail-a-bike, even a trip out to The Hydrocut where I might have gotten him in a little over his head and he cracked a rib. There has been lots of good times aboard this bike and it has an established story at this point, no doubt in my mind that the bike has taken on its own character in the owners mind.
After 3 seasons of use, its looking a little haggard and needs a facelift / overhaul. The front brake gave out this year and he has been getting by just using the rear (yikes!) and the shifting is getting sloppy, no doubt from the cheap Acera derailleur being completely worn out and the build up of dirt in the driveline.
He asked me to fix the brakes and driveline, I've convinced him to go to a 1x driveline for ease of maintenance and lighter overall package. A quick go over and it needs a bunch of small issues addressed, but could also use some upgrades to really "unleash the beast" that this bike can be.
The brakes need to go. The low end hydraulic offerings from C'Dale are complete crap, we will be most likely swapping over to Avid BB7's for ease of maintenance and ultra reliability.
Tires are shot. I'm going to set him up with something with more volume that he can really get aggressive with. Thinking something along the lines of the 2.4 Ardents.
The crankset is also hurting. The bb is nearly shot and the old Octalink Shimano isn't the stiffest option out there. Might upgrade him to a nice Deore crank. As far as driveline, most likely a 30t chainring with a 11-36 cassette, 10 speed of course. This bike is going to be awesome once its done.
Stay tuned for part 2, the bike will be stripped and everything inspected.
