Righty ho, i have a slight problem, my drive side crank arm is causing me greife, i spin the crank arm and it waves in and out, so badly that the chain ring rubs on the yoke and midley slices the yoke(ont worr i stopped riding ASAP). All i was wondering was, Is this the bb bent? or are my cranks f**ked? the bolt was super tight holding them on.
My set up is:
T-rex frame
UN 53 bb
Middleburns in square taper
Anyone else had the same problem? will a new bb help solve this? (the bb is about 5-6month old if it makes any difference?)
AND...
To help me solve the problem i need a crank extractor. And was wondering what is possibley the best one available? Park tool? pedros?
I was looking at the park tool one on crc for 11.99(unsure of model number, but it has a long handle, looks slightly like a ratchet) Is this a good crank extractor? because i really dont want to strip them as i cant be arsed to shellout 50-60 quid for replacemtn burns.
Cheers
Tom
