Crappy Bontager Select Crank

In a sprint on Sat. my chain slipped off and I did the following to my crappy Bontrager Select cranks:



This sucks becuase I am feeling really strong and I have a crit. coming up on Thursday and don't have the money to replace in time. Anyone have any suggestions on what to grab to replace.

Someone on the team just offered me a Ritchey Pro compact crankset 50/34 for $40. That a good deal, would I have to change my current cassette of 12-25.

Thats a pretty decent deal as long as the bottom brackets are the same. I think the Ritchey is octalink??? The changes you will have to do are probably lower your front derailleur a bit and shorten the chain to accomodate the smaller rings.

no need to change the cassette right now. maybe later. IIRC 50-11 is bigger than 53-12 and 34-23 is smaller than 39-25 so when you have the spare cash and feel like waisting 70 bucks, a 11-23 cassette will be lighter, closer ratios, and more range. this is why i like the idea of compact cranks.

p.s. how the hell did you bend the ring?

Was sprining when all of the the sudden it felt like my chain snapped into, it had in fact slipped off somehow and did the damage.

I guess it was the massive amounts of power that I put out, went beyond the stress points for the metal . ..

Is this seriously cause for a new chainring? I've got a couple of busted teeth like that on my FSA 50-tooth, and it hasn't caused me any problems

The entire chainring is bent, not just a messed up tooth. Think I may be able to get away by just replacing the chainrings and not the entire crank, as tempting as it is. I am getting a new bike (Madone SSL 6.5 at a killer team discount) at the end of this year, so this one just has to last until then.

Just replace that outer ring (it looks like it was pretty severely worn to begin with, I think you've probably gotten the useful service life out of that thing). No need to ditch the cranks unless you're looking to spend money.

Seems to be just the rings. BTW your chain looks like crap, undercleaned and overlubed.

Yah, I stopped by the LBS and had them put a Ultegra 53t ring on there and a new chain, figured since I am getting a new bike in a ew months not to do anything drastic like put a new crank on.

I agree about the chain, it is undercleaned and overlubed. I had just got back from a 80 mile ride in the rain, I was in the process of cleaning/lubing everything up when I took these crappy pics.

They were all impressed that i was able to do that to that crappy chain ring though!
