mtb cassette

is it possible to fit a mtb 11-32 cassette to a road bike 27 speed with a triple chainset. if not what is the lowest gear i can fit with a road cassette im running 11-23 i think at the moment but want to do some light touring around cornwall and devon where its abit lumpy.

If i remember correctly then 28 tooth is the highest you can go on Shimano.
But anyway, 32 teeth with a triple (30 teeth small ring?) :shock: I don't reckon i could pedal fast enough to get any forward momentum

i forgot to mention it is shimano. do you think from 23t to 28t would make much of a difference, sorry for sounding stupid but 5t doesnt seem alot.

I think that it will, you can compare gear inches here if you have the time;

Otherwise wait for one of the cleverclogs who knows it all off byheart



Edit: Also loads of info in the sticky at the top of the 'Road beginners' section

I fitted an 11-34 on my touring bike, but I changed the rear mech to an mtb (XT, £11 secondhand from classifieds - any similar mtb mech would do) works a treat.
