crank set drive train info
 
All,

I am tearing my old Scott rigid frame apart and turning into a touring bike, to pull a yak I think.

The front rings are beat and so is the rear freewheel. I guess it's a freewheel since it is an early 90's mtb.

The rear is a 7 speed 11-28

the front rings are 24-34-42

Is this a good enough range for light touring up here in Maine? I will hit some climbs but not massive ones.

I am having a hard time on-line finding front rings that are not too expensive. It is not an expensive bike, so I have to go overboard on this part.

I guess changing the chain along with the rest is expected?

as always,

thanks

John

The range should be good enough unless you are towing a hugely heavy load. However, depending on your crank, you may not be even able to change the chainrings since many lower line MTB cranks have the rings riveted, not bolted, on. Even if the rings can be replaced, it might be less expensive to buy a complete replacement crank and newer MTB cranks come with a 22T granny ring.

You probably have a cassette, not a freewheel since freehubs were common by the '90's. And yes, if you change the cassette or freewheel, use a new chain.

Since posting I agree with you on a new crank, chain etc...
Thanks
