Cranks

Does anybody repair vega cranks, I have 2, one with a knackered big end and one with excessive side float which makes the bike that noisy you need earplugs

chiselspeed repair vega cranks, i think they upgrade to a better rod and big end.

As I've just found out . . . . J50 cranks are narrower (4mm) than J125 cranks

could somone clarify the rest ?

J50/Lui50 narrow

Vega wide ?

cento / J125 / startstream all the same? wide?

I don't know about the crank width and I can't measure it because it's gone to chiselspeed and the other one is at work, but I have another question. What does this cap thing look like that protects the thread on the crank , does it screw on , push on and can you buy them.
Thanks

the cap is a left hand thread cover that screws on to the crank thread to protect the crank threads from getting damaged when using tools like mag flange extractor or flywheel extractor.
its only small, about the size of a thimble.

Thanks for that Daz
