Replace it with anything other than a Shimano one - they seem to cut costs by making their rings very soft.
Stronglight or TA have lasted best for me, but Raceface and Blackspire wear well also.

Yes,as long as the bcd is the same

As to the model number,if you look on the back of each crank next to the pedal mount it will say-> m569
And i think it came out in '99,it was only out for a year then discontinued due to the cost of the outer ring/spider
There is also a spider adaptor for these models[lx,xt,xtr]it allows you to use 94/58mm rings
Hard to find though
This is what it looks like->

The M-number will be stamped into the rear of the pedal end of the crank. But it looks like an M569 chainset which was released in 1997 and quite quickly superceded by the M570 in 1999. This was mostly due to the expensive way required to replace the unique outer chainring. At the time there was a 5 arm adapter which could be retro-fitted so that you could use the much more readily available 5 arm rings. The XT and LX were also available with the 5 arm spider as standard, with the M numbers M739-5 and M569-5 respectively.

I've got the 5 arm XT cranks on my 1997 GT Bravado, and I've got the 4 arm chainring in my spares box. Might switch back one day because they are a good looking chainset in my opinion.

Probably get it for under £50 ,posted.maybe £40
Mind that it is new,and bound to be subject to US export taxes.

They do come up on ebay for between £12-£20,which is a good price indeed,but not very often.

AND I KEEP MISSING EVERY ONE :evil:
