Thanks for the deep responses! I really appreciate it.
Yes, by "brake bridge" I was referring to the brake arms, not the frame itself.
I forgot to mention that this rubbing happens only in one place only. Such like the "hop" is the issue here. But I don't think it's possible to avoid any hoping. The tubular was reattached to verify if this was the issue, but the rubbing hop still exists. Maybe the problem is with my lack of experience with attaching tubular without any hoping? Cause it seems like without any hop it should works on Conti Competition 25mm. It's hard to say now, cause I went for the 3-weeks climbing right after mounting the new bike. So I had to fix it somehow on the road. The only idea that came up to my mind was to rub off brand new brake pads to half, so I could tight up the brake caliper a bit to make more clearance.
So what do you mean by the:
You still need to get that initial stretch on both sides of the valve stem while mounting to help ensure that you eliminate the "hop" that can occur if you don't.
I'm not sure if I know this technique.
So, back to the main question about tubulars. The only alternatives with the butyl innertube I found is:
- Continental Force Comp. 24mm
- Tufo S33 Pro 24mm
- Tufo Elite Ride 25mm
I don't know nothing about Tufo, I heard bad stories about rolling resistance but I guess is the same with Conti Competition due to the butyl tube.
I can try go with the Vittoria Corsa G+ 25mm or S-Works Turbo 24mm but still looking for something more durable on trips.
