I am considering getting a OCR Touring and the LBS, even though they are listed as a Giant deale,r don't seem to know much about it.

Three questions:

1. It has a TruVativ Elita ISIS, 30/42/52T crankset. What is the smallest chainring I can put on it?

2. It has a SRAM PG950 11-32T, 9 speed. What is the largest cog I can put on it? (Yeah I know I am fat, old and slow)

3. Does anybody have any recomendations on a bike shop in the South Jersey, Philadelphia, Wilmington triangle that knows and sells this bike?
