T140V Crankshaft Guru.

Does any one know who can repair/balance or supply refurbished or new cranks in Canada or North America...I know Rabers list new ( out of stock ) I can get it done in the UK at a push but stuff like that is hard to explain in your hand luggage, thanks for any info...

I would try MAP. I believe they have billet units available that are supposed to be outstanding.

You might need an outstanding bank balance to buy a new crank from MAP,but a good item.It would be good value if you're racing and regularly breaking cranks,or they're failing crack tests.

It would be a lot cheaper to buy a used crank.If you buy a used one,look for one that
A: Has not been re-ground and stiill measures OK.
B: Will pass a crack-test,or you get your money back.You will need to pay for the test,even if it fails (still good insurance).

What's wrong with the old crank?
A lot of places can dynamically balance a crank.Tell them not to change the balance factor,you'll be better off.

JOB has new and used replacement parts as well.


Both have good reputations and are in New England.
