Cassettes, chains, cranks are they compatible..?
#1
Hi... I bought 2 second hand wheels for my Gary Fisher bike..
The rear wheel came with a new 8 speed cassette marked... Shimano Hypergluide HG.
After reading the spec. list of the bike it lists the chain as Shimano CN-IG51, 1/2 x 3/32" ..and the front gear chain as SR XCC-150 42/34/24 crank..
The original cassette was SRAM PG830 11-32 8spd

My question ...is the new cassette OK with the original chain and crank.
Just got me thinking when I seen HG on the cassette and IG for the chain..
Been riding with this set up a few days now and it seems OK.
Not sure if all cassettes, cranks and chains are compatible..so hope its not a stupid question...

Thanks..

Hi Rocky. Your IG chain will work beautifully with all other components that you have listed.
If anyone is interested in a little Shimano 'history lesson' - HG (Hyperglide) came first and greatly improved shifting performance of Shimano systems. Then they refined it to IG (Interglide) and it got better! Always remember, H comes before I in the alphabet. Smile
It basically comes down to the tooth profiles on the cassette, and ramps and pins on the rings. Up front, IMO, it's not that big of a headache. An IG chain will work great on a HG cassette but, not an HG chain on an IG cassette. It 'will' work, just not sweetly.
As HG and IG were both introduced in the 1990s, most anything by any other Mfr today will work equally well with either.
A lot of SRAM stuff was invented by learning from Shimano, and they still make parts that work with Shimano! SRAM is cool.

It can be almost ANY mfr, rocky. All new chains by ALL mfrs are, at the very least, IG compat.
I might recommend a SRAM PC-830, -850 or -870. Works on any 8 that I have seen in the past 20.
