1x10 crankset

Having to repost this as I seem to have somehow disabled the reply function on my original post yesterday, fuck knows how. Anyway, let’s try again.

Right, spring is/was in the air and that means it’s time to crack on with my lightweight summer commuter. I built it up last year based on a loaned Planet X nanolight 54 - 1x10, Kysirium wheels, Ultegra mech and calipers, chinese riser crabon bars, crosstop levers etc. Very light and a lot of fun. I was using a Shimano Zee crank with a 38 ring, which was a bit industrial and heavy. The frame has gone back so I’m now looking for another frame, and I want to replace the crank too. So what’s the nicest, lightest, BSA-compatible crankset out there that I can use a 40t ring on?

You could get a SRAM GXP carbon crankset and get a direct mount 40t ring.
That should be pretty light.

Nicest and lightest 40t single speed is Easton EC90 direct mount.

I like these

Ooh they are nice - what's that chainring?

There's praxis and wolftooth direct mount chainrings too for the SRAM cranks but they go only to 42t.

Also, you can apparently fit a lighter BB30 force crank in a threaded BB. That, with a direct mount ring would be seriously light.
I have one in my parts bin, I'll report if I can make it work

Ooh.....nice. The Sram looks good too, I’ll look into that. Ta

Interesting, tell me more....

Yeah I got a pair of these from China. Waiting for the wolftooth chainring to make the experiment

I really like the cheap Origin 8 SS chainrings. 40T up front and a 9-42 cassette

Got a link to the chinese version? Keen to try something similar

It should work but if you wait a few days I'll report on this

Good work, thanks everyone. Lots of choice out there, mmm.....

I'm not in a hurry on this one, so I'll wait for your review, cheers

I got it working now. When you account for the BB it comes at about the same width than BB86, so I used a similar arrangement with the spacers.
The ZTTO bottom bracket is weird, couldn't find any compatible tool so I used a tube and some grips. Ordered one from China.
All in all, very light but fiddly. You need a 103mm spindle, so only BB86 compatible cranks like Force. I think it's possible to put a wider spindle on Red cranks, but can't confirm
