Chainring question
#1
Hi
I have a Shimano FC-650 crankset and am having a hard time finding a 44 or43 tooth outer ring......is this what they call a 130mm? and if so will all 5 arm (hole) 130mm rings fit? type A

This is a trek bike that I am building up for expedition touring and I have all ready gotten all new rings for the inside as well as a new BB the 46 ring on it now is to tall for a heavily loaded bike to be of much use.

One more thing... will all Hyper glides cassettes fit all HG hubs I mean other then a 7 speed is for a 7 speed... are the numbers after HG- referring to the gearing of the cassette?
Thank you for your time

130MM refers to the bolt hole spacing on the ring. Not sure if all 5 hole rings will fit.

Thanks for that, any help with the HG casttes? I'm looking to get lower gears and don't want to buy some thing that will not work.. I have found one that will do as far as the gearing and it has the same amont of gears and is also a HG I have now so will they swap out?

they should fit your hub ok, but spec your rear derailleur to make sure it can handle the the tooth spread

thanks and yes I have already gotten a longer armed rerailuer to handle the 34 as the one thats on the bike on will only go 28.....
I have also gotten the 44t ring I was looking for BTW it's 110 not 130mm But alls well that ends well.
