Apart from the obvious, eh!??!?!

Need a break from trying to get tubeless to work on a new build. I have Panaracer Rampage mounted on Arch rims with Conti MTB26 tube within. Everything is brand new.

I'm noticing a rather large mismatch between the tire and rim, creating what could be described as a "hop" in the rim. I'm wondering if the shallow depth of the rim's bead lock is causing this, especially since the mismatch occurs close to the stem of the tube (that general area).

Anyone have any input on this? I'm greatly loosing patience with the set up and was hoping that I could just run tubes and be done with it all, but what I have now in unrideable.

PATIA!

Have had similar problems seating a tubed Rampage. Not knowing the deets, going back to square 1 - please take no offense. Talc is a tubes best friend.. Inflate to 10-15 psi, close valve, remove presta lock-ring, push valve in, hold, and at the valve area push tire from side - side. Doing this may help to better seat the bead, and eliminmate the
hump-lump-bump.. Hope this helps!

No offense taken. I've been using tubes all my life, but i've never needed to do that before. Never even heard of that before. I'll give it a try.

Thanks.

Well I was really hoping that would work, but it didn't. I started to suspect my tape job, but that was ruled out when I tried with a couple of other tires and tubes and even narrower tape.

Looks like it's time for new rims again. ... and tire levers.

Thanks again for the tip though. :thumbsup:

Sorry it didn't help. Doing this assures the tube not interfering with the tire/rim bead. By chance, does the tape extend up onto the bead area?
