I must be doing something wrong. I have two new sets of OneUP pedals (one set is a warranty replacement) and the pedals seem to bind when tightening at finger tight.

The issue occurs with the following:

• without any crank boot covers
• with 1 and 2 pedal washers
• on two different bikes
• right and left pedal on both sets

Am I doing something wrong? Or are the OneUP aluminum pedals incompatible with SLX M7120 crank arms?

Subscribed. I dont use either the pedals or the cranks but I’m curious how this turns out. Sorry I can’t help, other than to ask if you can look at the pedal bearing to see if the crank &/or washers bind the bearing when tightened.

Yes, it looks like the OneUP pedal washer / seal assembly binds into the bearing when tightening (even at finger tight).

Greetings,
Yep. You're doing everything right and clearly there is binding when the pedal is tightened. That's helpful since I was considering these for my (SLX) bike.

Edit:
Not sure if this helps.

NOTE:

• Uninstalled pedals have a minimal axial movement built in that is eliminated when fully install on cranks.
• The retaining O-ring is only to keep the flange washer and seal on pedal in the box and for assembly. It is not necessary for the function of the pedal and can be removed.
• Out of the box our pedals have some resistance to free spinning by design. This can be adjusted by adding or removing grease upon disassembly. Free spinning will increase over time and wear of the bushing.
• These pedals are not compatible with crank boots without modification to the crank boots. We recommend removing crankboots before installation.
• We always recommend the use of pedal washers when installing your pedals.

Does that apply in your case?

They seem to be great pedals and wished they worked. I even got some tiny washers to put on the middle/center pins to make the pedals concave.

Just to add, OneUP support has been responsive in giving me a replacement set. I just wanted to post here, as a sanity check, before I send back both sets back to OneUP.

Those big inboard bearings sure seem to be an issue with that crankset. I bet that shimming them out to spin well means not enough thread engagement.

As a test, I tried 2 pedal washers and they still bind. I wouldn't want to use 2 washers or more.

They aren’t supposed to spin easily/loosely when tightened.

I saw this and asked OneUP about it. They advised that the pedals are ready right out of the box. I didn't want to remove the retaining o-ring for warranty purposes. The pedals have no issue free spinning, as shown on the video where I spin them off the crank.

My wife has those pedals on Raceface cranks. They fit fine, with no problem spinning, but you can get a crank boot that fits under them, so I had to 3d print some with huge cutouts.
