I recently purchased an 80's Marnati and need some advice on gearing.
The chaingrings are 53/43 and the six speed cassette is 13/14/15/16/18/20, which yields a range of about 57-110 gear inches.
I've been riding fixed for the past year with a range of 68-72 gear inches, and the range on this Marnati feels kind of high to me. I like to spin rather than mash, and the current gears on the Marnati only give me 2 combinations lower than what I'm already riding. It would be nice to have something lower for going uphill.
First of all, is this a typical gear range from that era or something more specialized for racing?
If I want to change out, should I just look for an NOS 6 speed cassette on Ebay? I'm not sure what is compatible with this (Campaganolo Record low flange hubs and Super Record rear derailleur). Any advice on a good all-around cassette range would also be appreciated. I'd rather not change out the front, since Campy chainrings are pretty expensive.
