I like the sram direct mount best out of all the interfaces. Currently running with a OneUp ring. Where I see room for improvement would be a simple way to adjust chain line without spacers and whatnot. Seems with 2 threaded locking collars this would be simple.

I have the Hope evo cranks and their proprietary ring and mounting interface. I also have the RF cranks and rings.
They both need to be checked and tightened at least once a month. They’re not always getting loose but have when I went longer without checking

 

I use both 104 and 96bcd Shimano cranks. Not because of the chainring interface but because of the 24mm spindle and quality/durability of the proven design.

Second choice would be RF Cinch.

I completely agree and in hindsight I will never buy a 30mm axle crank set for my Mtn bikes. Sure they may be a little bit stiffer but the BB's are just not capable of handling the load and always need replacement. Especially on a SS or any MTN bike that gets rode hard.

 

104 4-bolt (Truvativ, Shimano and White Industries) and SRAM XX direct mount.

 

Old style shimano slx triple with 104 bcd renthal chain rings in the middle position.
Never had a single problem with them in over 10 years. Have 4 sets in use.

 

Maybe I should give second place to White Industries, just for being a freaking gorgeous crankset. My only gripe (aside from the hefty price tag) is you have to buy their chainrings and there's no oval option yet. Then you mine as well use their BB. It adds up pretty quick.

Maybe one day I'll splurge but it's really hard to blow money on that when you can pick up a SLX or XT crank so cheap, and the BB's work better. Plus you can use the saved money towards good wheels, or better brakes, or suspension, etc.

Woolftooth makes a camo slide for WI now.

I've always had a thing for Middleburn cranks. Similar in price to WI but use a 24mm spindle & 104bcd spider. I'll be on XT 8120 for my next build though.

 

White Industry M30

I've admired White Industry cranks since they finally made the M30. I'm currently using their pricy BB with my Hope cranks and it's actually holding up better than the Hope BB did.
But seriously the Shimano XT cranks are your best bet for longevity and less drama.

I use a Raceface cranksets with a Shimano BB. Those Shimano ones never die.

 

Agreed, XT and XTR BB's are really good for the money. If only there were more crank options with 24mm spindles, and all BB's were threaded, there would be no need for spendy BB solutions...

 

RF Turbine Cinch with a E13 BB. I actually just removed a ten year old 104 E13 XCX because I got tired of it loosening at random times. I also went from 180 to 175.

Anyone need a black 104 Race Face 34t narrow wide with one short ride on it?

 

104BCD HollowTech 2 & cheap Shimano threaded BB's on 3 of 4 bikes.
The road bike has a 130BCD Ultegra 5 bolt crank and the Anthem has a pressfit BB.

 

Are you sure this is Single Speed related? Maybe it should be moved as a Crank is universal to all Bicycles?
Old Suntour's from 1987

 

Some cranks aren't suitable for single speeding.

Shaved XTR-m960s with the, almost impossible to find, 102 bcd. Wolf tooth are the only rings I’ve found

 

104 mostly (Truvativ Stylo & Carbon, Shimano cranks) with BlackSpire, MRP and Shimano ringythingies. I have some old stuff too... White industries square taper (small herd of BB-UN-73's new in boxes), Shimano XTR Octalink and other SStuff.

I ran the White cranks on a Turner FS 29er that had like 2mm chainstay clearance on drive side. Those cranks never flexed. I laughed many times, reading about people grousing about how bad flexy square taper sucked.

 

Raceface Cinch. You get more bang for your buck when you swap chainrings rather then cassettes.
