On Sun, 13 Feb 2005 10:44:16 -0500, "Chris Hughes" I am in the process of building a wooden framed bike. No, not bamboo. but I had considered building one of laminated split bamboo as in a bamboo fly rod. The bike will be along the same principle of a strip built kayak. I will also build laminated ash wheel rims. Should not be a big deal but what do I use for brake pads. Unless you plan to put a metal facing strip along both sides of the rim, I would remonned that you not try to use rim brakes. Employ a hub brake, either disc, roller or drum. I know that wood rims are or were until recently still avalible so I assume that they and wood rims of old used rim type brake. This depends on your definiton of "recently", and no, the literature that I have, and that I have seen, shows that all such units used hub brakes. There may have been units that used a caliper brake on a wood rim, but I have not seen any described in the material that I've come across. While the bike will be a just a show/club ride bike, it will still need to stop and I don't want to damage the finish on the rims any more then I have to. I was thinking cork as it was used with early carbon fiber rims. Wood rims will work best with hub brakes. I assume that you'll be using this with tubular tires; that's the easiest way to accomplish what you propose, as it does not require clincher flanges. -- My email address is antispammed; pull WEEDS if replying via e-mail.

Wood rims will work best with hub brakes. I assume that you'll be
using this with tubular tires; that's the easiest way to accomplish
what you propose, as it does not require clincher flanges.

Make that "I would recommend" (It's early, and the teapot is still
brewing.)

Peter at Vecchio's was advertising some a week or so ago, and I bought a
pair from him a few years ago. They're made by the same people in Italy
that produce tortellini by hand 🙂.

Could you elaborate on the problems with hub brakes on wooden rims?

That's just W's point - Hub brakes obviate the problems of
stopping with wooden rims!

I apologize.
Sure, but not as well as:

There's no particular reason bicycle brakes should work with
a wood surface. Braking is
turning motion into heat. Wood doesn't do that well. Not
with rubber pads, not with 'ceramic' green pads, not with
felt pads, not with cork pads.
When we still sold them ('82? '83?)for track bikes, we'd see
the occasional attempt to ride in traffic. Wild theories
about various pad materials all ended up dismally inadequate.
They were never 'better' in any way, just an aesthetic
statement. Which is OK until one reaches for other 'benefits'.
But if you simply desire a striking, distinctive track
wheel, by all means go for it. Cheaper than 'spinner'
covers, anyway.

I found Jobst Brandt's 1959 Alps trip report interesting. Wood replace
aluminium to stop the tubular glue melting on descents.
google or untangle this.
