Rear Cassette

[maggiolo72]

Hi all,

now on the rear i have an Hyperglide 8v cassette 11-28 with a deore xt rd m739 Derailleur and front 22-32-42 XT crank with xt Derailleur .
since the cassette is old and ruined i buyed new crank and new chain and i whant change it.
Can i put the 11-30 or 11-32 or 11-34 without problem ?
Any suggestion for the type/brand (xt, acera sram...) ?

It will fit fine, you need the correct length chain. Wrap the chain round both big front and back and add two links. No need to run it through the rear derailleur. Tihs gives you the correct length.

Personally I prefer SRAM cassettes. They are lighter, cheaper and more durable than Shimano in my experience.

Re:

Ok, perfect.
just another questions, making two counts with the 11-30 the difference is only 1\2 ring.
what i have to do ?

I think something got lost in translation...see here how to get the right chain length. Going from a 28T to 30T rear may need no increase in chain length, depending on how long your chain is.
