33mm Seat Tube Q

[Jason Musgrave]

By what method are folks attaching a front changer to these units?

33? 3.3cm? you mean "1.25" / 32mm" I could see 33 with paint.
Shimano uni-band here if that's the case. Rock On, JM.

The Columbus catalog lists a 33mm XCr seat tube, kind of a headscratcher to me. Singlespeed/track/cyclocross, maybe? Pegoretti-derived weirdness, perhaps?

[Jason Musgrave]

Steve that's the one. It yields a more usable post size than a 31.8 tube. It's Dario's tube, wondering how cats are working with this.

One of E-R's 32mm F-Der braze-on mounts should jive fine, if it's not built yet. - Garro.

Yeah from a framebuilders perspective that works. I'm wondering what cats with Pegs are doing with these units?

[johncaletti]

how about a shim under a 35.0mm FD clamp?

Pavarotti is supplying a custom clamp for frames using this weird seat tube.

La suocera, la nonna, lo Zio bonzo
(che non ci degnerà di sua presenza)
e cugini! e cugine...
Mettiam tra gli ascendenti
ed i collaterali, un due dozzine,
quando alla discendenza...
provvederanno assai
vostra grazia e la bella Butterfly.

Ciao,
the seat tube is 33.5 .9 thickness at the join with the top , the frames will be supplied with the seat collar and FD clamp on for this diameter , it is true that Columbus has on catalog a 33 seat ube , they can provide a nice Fd alu clamp on.

The 30.9mm ID (33.3mm OD) seattube is available for everybody at Reynolds and the clamp can as well be purchased separately from 2soulscycles (Germany).
