Hello ratrodbikes!
Ok... to start with.
I found a specialized rockhopper on craigslist, the ad said make an offer. So i emailed an offered $8, well he took the offer. The rockhopper needs a lot of work. Its an 18" or 19" frame. Almost everything was shot on the bike.
I'm building this for my 7yo daughter. I am going to use the original fork, with a bmx stem an bmx bars. I am also going with 165mm cranks.
I want to build 24" wheels. I want a geared rear hub with a brake, I'm thinking a 7 speed hub. Ok here's where i need help... I dont know what the tooth count on the front sprocket should be. Originally the front sprocket had three chain rings but I would like to build it with one front chainring.
I'm building this cause we do a lot of city riding. The extra gears will help her pedal at her own pace once she learns how to use them.
Thank you in advance for any an all help.
