Well the consensus seems to be get a new freewheel with 28 teeth. That sounds good to me, the price fits too. I don't plan on using the big/big combo, but I have an extra chain laying around that I could salvage extra links from if needed. I've been using a mountain bike with some city slicker tires for some time now, and it just wasn't high enough for the downhills and I never used the small ring. If anyone knows about Golden, CO they know the foothills can be steep, and I just can't do Lookout Mt or Golden Gate Canyon with this gearing.
I think I'll just go for the freewheel and if its not low enough, I'll just have to work on those legs!
Thanks!
