Thread: Raceface crank removal question

So I'm getting a little confused with how to remove Raceface Evolve cranks.... checked online earlier & all made sense until I stopped passed the LBS to order the new chainring I need (broken tooth on the existing).

Guy at the LBS says Raceface cranks should have the funky 8/10mm inner & outer removal bolt thing on the drive side IF there is no pinch bolt holding the non-drive side crank on. If there is a just a regular bolt holding the drive side on, & if the spindle is all hollow, he reckons it should have a pinch bolt holding the non-drive side on.

My cranks only have a normal bolt & no pinch bolt. Raceface website says I need a crank puller if it doesn't have the 8/10mm inner/outer bolt thing.

My last bike had square taper cranks & so my existing crank puller won't work as the inner pin is too small. I figure I just need to get a new crank puller with a bigger inner pin (eg: Park tool Cwp-7) & all will be well.

I'm hoping mag wisdom will clarify before I order the wrong tool.

Assuming the older internal BB. You can scratch the new crank puller. Use a bolt or random pin that will press against the other crank bolt on the other side. I used to have a similar ordeal with the Truvativ Isi-shit. The shaft was hollow so I used an old bolt that just went through the crank to the other bolt. Works like a charm and does not cost me $20 more. If it is new external BB then it will have the pinch bolt as described and rubber mallet might help persuade things loose.

Sorry should have said its an external BB & definitely does not have a pinch bolt. No bolts at all on the non-drive side, its just a hollow axle.
I'm guessing the axle & non-drive crank are 1 piece (?).

I did hit it with a wooden mallet as hard as I dared & it didn't move or loosen at all.

New crank puller is $15-ish dollars. I don't mind spending that so long as it works.

so did you remove the bolt? If there's no bolt on the non-drive, it sounds like it's a standard X-type, which is self extracting (meaning you don't need a puller).

Assuming you did remove the bolt and the crank is still attached to your bike, it sounds like the self extracting ring fell off at some point. This means that you can either 1) buy a crank puller for $15, or 2) buy a replacement bolt that comes with a new self extracting ring for $8: http://www.shopbot.com.au/ps-racefac...-30768489.html

This thread is useless without pics!

I know what you speak of. You can order the new Park tool. It's the same as the old tool but come with a little round piece that increases the diameter of the "punch". It's tough to describe without a pic. The bigger diameter needed happens to be the same as a dime ($0.10). Sorry Canadians if you can't picture this...it's much smaller than a looney. wink

Edit: See that really thick washer on the right hand side of this picture? That is the "punch" you are replacing with a dime.



What you do is put the dime in and make sure it fits flush against the end of the splined spindle and then screw in your old crank puller.

Using a dime can work if the crank isn't on too tight. If whoever installed the crank didn't use the proper torque, it could be on too tight and all you will do is bend the dime (maybe two dimes is the best way to go).

Disclaimer, the dime trick is totally ghetto. I would go to the shop and borrow the round piece, pay the shop to take it off, or buy the tool. Or, risk it with the ghetto dime trick.

thanks conundrum - l'm all about the ghetto way if it works. LBS didn't have the new puller in stock & buddy was trying to tell me I shouldn't need one.

Bike is still very new - no way the self extracting ring could have fallen off. This is the first time anything has tried to be removed. I was almost wondering if it should come with the self-extractor, but for whatever reason didn't?

pic's (just for Dave)...

non-drive side:


drive side:


without bolt:

yep, old puller with a dime on drive side should work. fwiw, I like the Pedros crank puller, it comes with both sizes and they're interchangeable

the crank puller I have now looks very similar to that, probably just the MEC version. I guess its 4-5 years old & is not interchangeable with ISIS cranks.

you need the new puller. I have the same cranks and had to get the new puller. The larger diameter on the push unit and they come off very easily. Don't beat on them. If they need much force, something isn't right.

I have the park version of that pedros. It works great. I had the old version which is the exact tool as the new one but to get the little bigger diameter piece you have to buy it as a package deal...no way would Park sell anything metal for less than $8.

Yep, those are the cranks that you can use the dime trick on.

I just wanted to check that this was NOT the raceface, strange, own, self extracting bolt, thread on thingy that gets lost.

It seems the CAD has lost some clout..
& seems I am buying a new crank puller

haha, great picture though

I had the same exact set-up as you did on my Giant Reign.

The bolt was the same one as yours. I couldn't get it out and brought it to my LBS. They could't get it out either and ended up breaking their self-extracting bit clean off inside my bolt.

Only way I ended up getting the bolt out was to drill some holes and make a channel, then use a flat head screwdriver and hammer. I hammered and hammered and after probably 20 minutes it finally came lose. Wish I had taken a picture of the bolt so you could see what I was talking about.

Had the replace the bolt. What a pain.

Goodluck.

I also have this question. Double check that there aren't any reverse-direction threads in the outer edge of the hole you pulled the bolt out of on the drive side. I tried to pull a set of atlas cranks I lost the outer cap on when I still worked at a shop and it could not be fucking done with anything we had on hand. I just ended up borrowing a buddy's cap and it came off fine.
