165 mm Crankset on shorter travel Trail bike?

[Duffman]

I know shorter cranksets on Enduro bikes are all the rage, but is there a benefit for shorter travel trail bikes? My Ripley AF XL came stock with SLX 175mm cranks. The low BB does have some pedal strikes, and I'm more of a spinner whose always used 170mm cranks on my road bike, so I was thinking of going shorter. 170mm seemed like a good place, but I wonder if that little difference would even be worth playing around with, Any other almost 6'1 riders go to a 165mm length for a bike that they will be pedaling a lot, not a downhill or enduro sled? Pros and Cons here?

I put 160mm Canfield cranks on my Rail. Honestly I can only feel a difference compared to my Spur with 170m cranks for about the first 10 seconds after I switch bikes. If you make the change I'd go 165 or less.

Can't comment on short travel, but I went from 175mm cranks on my 160mm YT Jeffsy to 165mm on my 160mm Patrol (mullet). In between switching those bikes I got my first road bike on 170mm cranks. The 165mm took a bit of getting used to, had only had that length on DH bikes before, but now I see no downside. I am also a spinner, especially climbing MTB, and have no problem getting enough torque to get up technical stuff. Bit shorter than you at 5'10, 200lbs so decent power. Biggest benefit is less pedal strikes with low BB.

I just switched from 175 to 165 on a Scott Ransom. The goal is to reduce pedal strike. I keep telling myself how much difference can 10mm make (that's what she said)?? But I'll let you know how it goes....

You know you want them…$850?
LOL

Uh, I'm a beater. SLX level is far good enough for me and my wallet (shame I can't find any 165mm around in stock though)

Does a $1k crankset come with a motor?

[rideit]

Sure, I’ll toss in a motor!

Why is it impossible to find a Shimano SLX w 165 mm arms? Wanted to try this fairly cheaply and not need new chainring and such, but these are nowhere to be found.

Shimano is a slow moving, decisive dinosaur and is/will be far off the back on the short crank trend; likely just waiting until the trend pendulum (trendulum? - gonna trademark that)swings back to 170mm.

I honestly think they must have made a batch of 100 of these and that's it. I scored one 2 years ago on a German website and feel like I was about as lucky as finding a gold bar on the sidewalk. The XT was also available at the time, never saw that one again either...

BC.com has a few in stock

Also 1 pair of XT

I've been 165 curious but haven't bothered as I don't want to get sucked into needing all 165s on a bunch of bikes

[Duffman]

The ones they have are the 7130 / 8130 which is a super boost chainline unfortunately.

Just re-read that. Good god, further proving the point that super boost is idiotic.

Thunder Mountain Bikes out of Sedona has the XT 8100 in the 165mm length in stock. I ordered one a couple weeks ago.
