New bike frame is blooming low (Stif Squatch) and I'm catching my cranks on everything (175mm).

Is 165mm as short at you can get?

Seen some Canfield cranks at 160mm, am I missing anything else?

if you pick the right cranks, i.e. ones wth solid arms you could get them cut down and tapped to any length using somewhere like:

or perhaps make use of Hope E bike cranks? they do a 155mm or one of the other e bike short cranks that use ISIS BB?

SRAM did some sx cranks down to 155.
I have cranks from 140 through 152 with SRAM direct mount from the factory that make vpace, trailcraft and spawn cranks. Those are available in 140, 145, 152 and 160 iirc
Most decent kids bikes are now coming with more appropriately sized 1x cranks

Just 165 from 175 does make a huge difference on what you catch.

As above I made a change that affected height by about 8mm and that took a very pedal strikey bike into non-issue territory.

Have 2 sets of 1x shimano cranks in 165. M8000 and M7100. No idea current availability, mind.

@paton.. I don't think square taper BMX cranks and 5x100 spiders are going to work in this application.

Hardtail Party just did a comparison video on YouTube about short vs long cranks (155 all the way up to 175 and it’s quite interesting. Personally I like 165 cranks

I've got the same frame and recently put some 165mm race face cranks on. Feels better now. I also watched the hardtail party video and can see what he means by the reduced hip involvement when peddling.

RACE FACE AEFFECT 24MM MTB CRANK ARMS - BLACK - 165mm.

Just remember that some companies use the same length crank but drill the hole in a different place so your 165 cranks can be the same overall length as their 175s. I believe Hope’s 165 cranks are not like that and can be quite a bit shorter than rival makes. Canfield is also shorter overall.

I love my short cranks (165mm on all my bikes (5'10" btw)), but remember that your seat height will be affected. Going 10mm shorter on the cranks means your seat needs to go up 10mm (and maybe back a bit) if you want to keep some pedalling efficiency.

Crumbs, forgot i posted this, cheers one and all.

As 165 are readily available without a silly price tag will take a swing at some second hand cranks and see how I go.
