More Mid-Compact Talk

[Lovetoclimb]

It is all the rage right now, along with retro style shoes, aero road helmets, and hi viz everything! Consider me on board, after finding myself in the 39-27 far too often, I am ready to experiment with some smaller gears.

Here are my two cranksets on two different road bikes:
1)2010 Super Record 11s, stock rings 53/39, 135 bcd spider, on a steel Columbus Spirit road bike
2)Cannondale Hollowgram SL BB30 with FSA 11s rings 53/39, 130bcd spider, on a 2010 SuperSix

Anyone have thoughts on the best options for converting either crankset to 52/36?

Best I can tell, FSA does not make a Campy 11s 52/36 set of rings, and Campy makes them in either Athena level (silver or black) or Super Record level (that off grey/green color of standard rings). I am banking on having to switch to a 110bcd spider on either crankset to accommodate the 36 tooth inner ring.

You definitely have to go to a smaller BCD than 130 for a ring smaller than 38t. May as well trade one of your current cranks or buy a different one.

This. 38 on a 130, and 39 on a 135. Small as you can go.

Get a 110 spider for your Hollowgram cranks, and a set of Praxis compact chainrings- they will work great with your Campy 11 speed.

Two of these.
