46-30 crankset options
After the Farmer's Daughter ride this weekend my lovely wife has requested some lower gears. What are my option for a 46-30 crankset? The main caveat being a threaded bottom bracket with non oversized spindle. Her bike is Di2 and there isn't clearance for wires and a 30mm spindle. Would prefer to avoid square taper if possible. The only thing I've come up with so far is the just released Shimano FC-RX600 crank.

There's a thread on here titled, What are the big 3 waiting for to go sub-compact? which has a great deal on this topic. And Mark McM wrote more detail about using a SRAM Force cranks with the removable spider to swap in a MTB spider to run lower gears in a thread titled - Subcompact gearing.... that I started a while back. I've done that on my Litespeed, running 42-28. Haven't looked for rings to do 46-30.

Praxis makes nice sub-compact cranksets that are reasonably priced.

It’s not cheap, but the Rotor Aldhu comes in a 46/30 with a 24mm spindle. I’m running the 30mm version with a CX70 FD and 11-speed, works great.

I like the Sugino, but does anybody ever have them in stock? The Rotor also is kinda cool and I wasn't aware of it.

Dan - Absolute Black makes some 46/30 chainrings that bolt directly to standard shimano 4-arm cranks. i have a set and confirm they shift really well.

Why the reluctance for square taper? There's 94mm BCD square taper cranks out there that you can use as a double, just leaving off the inner ring.
Otherwise, SRAM has a variety of cranks with removable spiders. Buy the crank you want, then swap in a "mountain" spider.

46-30 crankset options
The Easton SL90 crank arms can be coupled with either single ring or double, direct mount. They offer 47/32, 46/30 and other road combos. bb options for almost all threaded or non threaded standards.
Super nice cranks. Last edited by sparky33; 05-21-2019 at 06:55 AM.
