i cant get the pedal arms of the botem bracket tho?
do they just "pull" off? weve tryed usinga bearing spliter and loadsa pulling tools but it dont move?? i just wana ride haha

[draper]

you can get a special tool for that aswell, kinda like a steering wheel puller, i used to have self extracting crank bolts (or whatever therer called) when i used to ride

how does that work? do you have a pic of the tool?

[draper]

i lost it ages ago lol

its like a threaded socket you wind into the crank (where the bolts go) and as you tighten it it pops the crank arm off the spindle, if that makes sense

yeah thats it fella

i ended up getting some of these tho http://www.bikemannetwork.com/biking/p/COMPBBPRTCRKBOLT/CR2198

meant whenever i snapped a BB i could swap it quickly or while still out riding if i had a spare with me

Top man, thank you.

whats that do^?

[draper]

when you undo the crank arm bolt it pulls the crank arm off with it - no need for any other tools, a godsend when i was miles away from home and broke a BB as it was before i could drive
