Hi all,
Lost an axle cap - the dust cap looking thing that preloads the bearings in the ATAC pedals - and Time is telling me they no longer offer the part. Canadian and US distributors have it marked as discontinued. Time says I have to buy new pedals, regardless of the fact that they still offer pedals that use this part. I am pretty pissed off.
Anyway, I need the part. If you have any old beater XC/XS or Alium series Time MTB pedals let me know. I'll buy the dust caps from you. They look like this:
They don't have to be the silver painted ones.
Thanks in advance!

Got the 31.8mm Thomson today. I had to pry it open a touch, but it seemed to fit fine.
I trimmed back all the paint so that it wouldn't rest under the clamp, sanded the raw seat tube, light coating of grease, and installed the 31.8mm Thomson. Went on and torqued up to 3nM no problem. That said, the "defective" clamp seemed to be fine at 4nM for the past little while.
Haven't ridden with the Thomson yet, but I am pleased that the paint damage is concealed and the install went totally fine. We'll see how it goes after I get it on the road for a few miles.

Could be your cleats and/or shoes. Try pedaling without clipping in.
Handlebars/stem could be the culprit as well. Try putting a bunch of force on those from a stand still (holding your front brake and pushing/pulling).
If it is the BB/cranks you could try squeezing them towards the frame with your hands (Sheldon's advice) to try and make them creak.
These things can be a real PITA sometimes.

Thanks again @jammy for the thoughts on this.
I have measured the tube, yeah. I was just mentioning the size of the existing clamp to bring more info to the table (and to point out the mistake I made assuming it was a 34mm).
The seat tube OD measures about 32.1-32.2mm at the very top (no paint), and more like 33mm where it is painted. It does have the sleeve added for a 27.2mm post, yes. I have had no issues with the seat post (Deda Superzero) slipping, even with the clamp torqued to 4nM, and the fit of the post is excellent.
The existing clamp seems to fit fine (as in I can fit it on the tube without any fighting) although it is a flexy clamp to begin with. I have the 31.8mm Thomson coming to try - I can always return it to Amazon if it doesn't fit. Otherwise I will have to look for a 32-33mm option. I really want the Thomson to work since it conceals all the paint damage (vain I know...)

Welp. The 34.9mm Thomson is far too large unfortunately. An extra bummer since it's tall enough to conceal all the paint damage, which brings me joy.
Even more frustrating is that the clamp that is on there is labeled "34", which I took to mean the diameter. Just now I threw it on the caliper and it comes up as 31.8mm. Welp x2. And I suppose this could be the problem.
Wondering now if I could get away with the 31.8mm Thomson?

Thanks for the comments fellas.
For the record, the "bad" clamp is marked as 34mm, I have a Thomson to try in 34.9mm. Seat tube OD is 32.5mm.
@PhilDAS, Frame is a custom jobby from a local (well respected) builder. Tubeset is Spirit HSS, so the OD of the seat tube is non-standard (at 32.5mm). Seatpost measures correctly with my calipers: 27.18mm, spec'd ID of the seat tube is 27.2, seems correct with the calipers as well.
@jammy, I was worried the clamp is a bad one actually as it seems to sit askew on the seat tube before I apply torque, which I guess could create an uneven force allowing it to slip upwards. I just received a Thomson clamp (inspired by Reilly's HSS frames) and I'm going to give it a try after work.
Hopefully the builder will fix up the paint under warranty. Right now I am definitely not comfortable with the ragged paint edge below the collar, and the exposed steel. Absolute bummer since the build is brand spanking new.
I appreciate the input!

Hi all,
Just finished building up a new frame last weekend. I went all out (for me) on this build so naturally I am getting a bit emotional about this.
Arrived home yesterday after 20km of commuting and noticed raw metal right below my seat collar. Upon closer inspection, it was clear that the collar had migrated up the seat tube (towards my saddle) and took all the paint with it in the process. Absolutely gutted. Two things strike me as odd about this:
Why did the collar migrate upward? I torque'd it to 5nM as per spec. After taking it off and trying to tidy up the failed paint, I can't even get it back on there anymore. As soon as I reach around 4nM torque it's already slid up a few mm on the seat tube. I don't think this is safe to ride without risking damage to the frame. Is it conceivable the issue is with the seat tube itself? I can imagine any taper in the tube underneath where the seat collar sits could "entice" it to move upward in use.
It seems to me that the paint failed particularly catastrophically. It looks as if it just cracked along the circumference of the seat tube and slid right off the tubing without putting up much of a fight. Sound weird?
My next steps are to get another seat collar (on order) and see if that one will stay put. I also now have to deal with trying to get the paint fixed up.
Any theories/input/comments/words of encouragement are welcome.

After telling Time I will never buy their products again, they decided to send me the part I needed. Closing the thread
