There are very few practical and beautiful double cranks out there these days. TA still makes this one in France. We configure it here with a 110 BCD double spider, but you can swap that later on if you want.
We've picked the most commonly requested chainring combos. If you want a fully custom set up, we have that here.
TA cranks use the ISO (italian) taper for their bottom brackets. You really want a TA Axix bottom bracket in there. They're well made and rebuildable. Available here.
TA crank orders usually take about a week to fulfill. We have to assemble everything, which means it has to get in on our service calendar.
The cranks come with the following, all installed:
Carmina arms with lockring. Carmina 110 bcd Double Spider. TA chainring bolts, steel. TA Zephyr rings. A note about the rings. They say 9/10 speed on them. We've used them with 11 speed chains with no issues. They were just made before 11 speed stuff was a thing.
It's ideal for bikes with 68mm bottom bracket shells, but can be adapted to 73mm shells as well. TA Carmina cranks fit any currently available Rivendell, all of the Velo Orange models except the Piolet and of course many more. Fits most bikes steel frames that are designed for 2.3" tire clearance or smaller. Not for steel bikes with clearance for 2.8" tires, or fat tubed aluminum mountain frames, or carbon frames with big chainstays.
Worried about clearance? Get a metric tape measure or ruler, some masking tape and a pen out. Add your crank length to 15mm. If you are running 170mm cranks, that means you need to factor a total crank length of 185mm. Measure from the center of the bottom bracket shell to that number. Put a piece of tape there and mark the exact spot where the crank arm will pass the stay. Do the same on the other chainstay. Then using calipers or a tape measure or ruler, measure across the stays, from point to point.
