I have a ig 11 - 30 t, 7 speed back cog. Is it possible to put on a11 - 34 t Shimano HG50 back cog?
Will switch to a SRAM chain as I have an ig chain on now. What problems could I experience, or
should this work just fine? This is for a touring bike.

My front chainring largest is a 48. Thank you. Email: [email protected]

I had to read your message a couple of times--in the courier font my newsreader uses, it looked like
you were asking for an "all - 34" setup!

This will work just dandy, as long as your rear derailer is a long cage (SGS) model, which it most
likely is. If not, derailers are cheap...

The chain will need to be longer than the original one.

By the way, what you want is a "cassette", consisting of 7 "cogs."

And I thought my 12-34 7 sp. was wide range! :-3)

May you have the wind at your back. And a really low gear for the hills! Chris
