slightly oversized seattubes (29.2 vs 28.6)

[mecse]

Hi folks,

a few weeks ago I bought a fabulous frame here:

And I finally started having time to build it up last week. I measured out the seattube with calipers… and it's 29.2 . Not 28.6.

This has meant that I'm having a hard time putting any kind of clamp adapter on there. Does anyone know of a particularly forgiving brand of clamp adapter? Or an alternative solution? I'd share photos but I didn't take any.

That 28.6 is the actual tube before powder. Odds are good most of the Shimano clamps, or after market (like Problem Solvers or Wheels) will work just fine.

You're gonna want to use a 32mm clamp with an appropriate rubber/plastic spacer.

this has been my experience. depending on the thickness of the finish, you may have to grease the inside of the clamp a bit or pry open just a tad by twisting a flathead in the slot. no biggie.

- sweet frame btw. that was a smokin deal. but by the looks of it, it's got a braze on, no need for a clamp

I know - I'm very excited to ride it. It's going to be gorgeous.

Pretty confident it's a clamp on :) I'll send a photo of it tomorrow when i'm at the workshop.

Thanks Eric - I figured it was something like that, where the paint and whatnot would add 0.6 mm. 0.3mm thick paint...

I figured the tolerance would be ok, and tried an Origin 8 (http://www.origin8.bike/product-description/?prod_model_uid=8223) brand one. It looks really ugly on one end when clamped (Will send photo)

I also tried the Parlee carbon adapter (http://www.amazon.com/Parlee-Carbon-Front-adaptor-28-6mm/dp/B001PT6PEK) - and this one looked like the two hole-sides were never going to align, without some serious push from my end, if ever.

Left scratching my head and figured i'd ask here before trying something else.

Yes, sorry, I meant the FD clamp. the seatpost clamp is definitely that and is as beautiful in person as you see there.

considering i'm helping him build it, i can 100% safely say it doesn't come with a FD hanger brazed on.

i think it's a combination of a few things, the 28.6 FD clamp we got is crappy, and we're trying not to muck up the paint, so... it's been a bit touch and go.

I should have mentioned this. TheGunner's been a huge total help (and lets be honest, we've had fun admiring and enjoying the frame) .

Campagnolo FD adapters are pretty forgiving..

Never mind..Valentino thinks there aren't any more 28.6 frames out there...Miche makes one also. Or like mentioned, 32mm one with a PVC shim.
