The cranksets for our Rhygin and Waterford road bike re-fits are assembled and ready to go:
Above from top left: Campagnolo Record crankset, Wetzikon chainring guard in original black finish, Sun Tour Cyclone Crankset with tripilizer.
As South Florida is flat as a pancake I decided on a single front ring for my Rhygin. The Campagnolo 10 speed rear cassette is more then enough gears even for an out of shape rider. I picked up a Record double on eBay cheap, removed the 53/39 chainrings and put an old Campagnolo 42T ring with no pins or ramps on the inside position with the intention of mounting a polished alu chainguard on the outside. Cyclocross World sells the only 135BCD chain guards that I know of. Unfortunately they are available only in anodized black.
So first order of business was to strip the black anodizing. Lye crystals dissolved in water had it all off in minutes and ready to polish. For a detailed guide to stripping anodizing and instructions on how to do your own anodizing see: http://www.focuser.com/atm/anodize/anodize.html .
For my wife’s crankset I needed 160mm crank arms. I found an old Suntour Cyclone 130BCD crankset the right length. A quick rub with steel wool got rid of the ugly logo. An old NOS 40/36 tripilizer (TA or Stronglight maybe -no marking) with polished rings replaced the Suntour rings which were way to big. If need be in the future I can swap the 36T ring for something smaller as with the tripilizer I am not limited by the 130BCD minimum ring size. But I expect the “Miami gearing” should be fine. A Cyclocross World chain guard stripped and polished went on the outside position.
With no hills you run a pretty narrow range of gears and with front ring combos like 50/34 I feel like I’m always in the wrong gear in the front. I prefer to have the front ring/rear cog combo I’ll be using 80% of the time be in a straight line to each other. So I think this drivetrain set up should serve us well for local riding conditions.
