Green QB and Rock and Roads

[Dave Grossman]

Can any green QB owners (I have a 62) confirm that they can fit a Rock n Road in their frame?  I'm running a 42 Supple Vitesse right now and want to max out some knobbies.

I assume you've seen this, it's very specific Dave !

Dave,

I have that bike, and those are my all time favorite tires.  I never mated the two, but I have had wider tires than that on my Quickbeam.

Hi Dave, yes, I’ve run Rock’n’Roads on my 60cm green Quickbeam. I don’t think there was 6mm on each side at the chainstays, though:

It was pretty fun riding in Annadel with a kickback wheel and those tires!

I have a green 58cm Quickbeam, and my original build used Rene Herse Hurricane Ridge knobbies (700x42).  That tire fits in front and is still on the bike.  In the back, it only fit when the wheel was towards the back of the dropout.  If the wheel is towards the front of the dropout, then it rubs.  I use most of the full length of the dropout for gear changes, so I need my rear tire to fit EVERYWHERE.  I switched out to a 700x40 with less tread.  Moving forward, I may switch to Steilacoom (700x38) or I may try to do some chainstay manipulation, but for me the Hurricane Ridge only sorta fits.  If I was going to use my Quickbeam as a single gear bike, I'd use a chain length that allows it.  As a multi-gear single speed, it's a no-go for me.

Ah, yes, Bill is correct. I had the gear changing in the hub when I ran the Rock’n’Roads, and the axle was back in the slot. Current setup is two rings and a double cog with fenders and 37mm tires for two fixed gears with minimal axle movement. 

I think I posted the last response from my phone, which is like writing with an Etch-a-sketch in the Google Groups current “quiet firing” of this service.

Thanks for the feedback.  I've been running Soma Supple Vitesse in a 42 and they clear fine without fenders on Belgiums.  I tried to mount some Big Bens for fun and the front was fine but the rear didn't work.  I think a 38-40 is the sweet spot for the QB.  I'm debating throwing my SKS fenders back on and with those I used to run 35 Marathon Supremes or some 32 Gravel King slicks.
