evolve xc self extracting bolt

PRCurban

Hi guys

The 2008 evolve xc crankset fitted to my orange p7 doesnt have a self extracting bolt. I really need to change my bb so is there any way i can remove the crank arms without this bolt? or do i need to order a new bolt and put up with the crunch of a worn bb for another week or so.

Cheers

If it is a standard cartridge BB, just use a crank extractor.

hi supersonic

The bb is the standerd race face external one that came as fitted.
ive got an old park ccp 2 but it dosent fit, any idea what crank extractor would do the job.

Another question, my girlfriends kona and my orange both have 2008 race face evolve XC triples and neither have the self extractor bolt, have race face stopped using them?

Cheers matey

According to this:

Should indeed be a extracting bolt.

post a piture of the bolt and bits you have removed from the crank end please.

Hi guys

The cranks have a M15 isis bolt similar to the ride crankset and looks like race face have been using these on newer model evolves, but havent added this to the tech pages.
Just need an isis crank remover like the CWP6 as suggested in the ride tech info and all should be sorted.

Cheers for your help and have a cracking weekend.

you probably figured it out already but i just did a hack job on my race face deus xc crankset because i lost my self extractor plug on a ride last year...

my hack is as follows:
1- loosten the retaining bolt a bit, leave plenty of threads still in the hole tho.
2- put a spacer into the crank arm hole resting on the retaining bolt head, this has to extend out beyond the depth of the crank arm hole (I used a socket from my wrench set)
3- you need a plate of steel with 2 holes drilled approximately the width of the outer dimension of the flange on the crank which is about 3"/8cm, the plate will rest on the spacer.
4- get 2 VERY sturdy bolts which have a low profile headto fit beneath the flange but still clear your external BB cups (my bolts came from an IKEA furniture set)
5- place the bolt heads under the crank flange so they can pull the crank arm away from the bottom bracket spindle.
6- the threaded ends go through the holes in your plate.
7- evenly tighten the nuts which will press the plate against your spacer which presses on the retaining bolt. The equal and opposite reaction is the bolt heads pulling your crank arm flange away from the bottom bracket.
9- your crank arm might even come off, mine did!
