Changing the chainring

[benb]

OK, my existing chainrings are 48/36/26, and the M410 and M443 are both 42/32/22.
So I think I'll go for this: http://www.woollyhatshop.com/Cranks...set-ISIS-48/38/26-175mm-SILVER/prod_4301.html
Price looks good.

Sorry Mac. If I didn't want the longer cranks, I would definitely have taken you up on your kind offer.

Thanks for all the brilliant advice.

OK, it's all done. It was pretty easy really, except actually getting the cranks off. Even with the tool it was very stiff, and I ended up having to stand on the handle of the tool to get it to turn.

Fitting the new cranks was easier - I didn't use the tool I just used the hex key to screw them back in which seemed to work OK.

It's now running nice and smooth and almost silent, bar some chain rub on the front mech in certain gears which I need to look at.

The longer cranks are noticeable too - a bit harder work in the same gear, but more leverage.
