thanks for the inputs,

Aeroman,

I like the idea of leaving the 52 on, I noticed On The Harris website Sheldon uses a 52/20 road /hilly area (my situation for the most part).

what about standard cassete gears? I know the ramps can cause trouble but is it absolute, could I surface grind the ramp down a bit or smooth them out so they dont grab?

I noticed the shimano BMX cogs only go as high as 18, id need a 19 or 20 , I would be VERY surprised if any LBS in my area carried anything but the shimano BMX cogs , Ill call.

Im not opposed to ordering online but it does get tiring, Good LBS are hard to find at least one like Harris thats willing to do non mainstream stuff . But again they have to make money too and Lance bikes are where its at.

I have plenty of stuff from broken up cassetes, though I can see the benifit of the "Non shifting" type of gear. Maybe Ill use the hyperglides I have untill I find a good size then get a Proper SS "Cog".

many thanks

"John"
