58 or 60T Campy compatible chain-ring?

[ProfTournesol]

I wonder if anyone knows of a 58 or 60 tooth campagnolo 10 speed
compatible chain-ring? It needs to have chain-lifters on it to
accurately lift the chain without over lifting it or failing to lift
it.
I'm no Robbie McEwan beating sprinter, I just want it to gear up my
Bike Friday (with 451 wheels) and currently I'm restricted to the
largest ring that Campagnolo make - a 53 tooth.

I'm glad you explained that. Having recently gone the compact route
with a 50/34 I was starting to wonder.

I understand that Greenspeed can make up chainwheels to any size you
like, they're fairly pricy though. Preumably a 135 BDC to fit Campag
shouldn't be an issue but the ramps and pins may be beyond them.

There were also some early SR chainrings in 135BDC, I've got a 54 on my
stationary system. Again no ramps or pins

Again , I know it is not exactly what you want but we have a couple of 55 &
56t to suit 135 Campy pattern , without the ramps & pins but for $25ea they
are a cheap alternative.

Or you could go Capreo and get a 9 tooth cog (9speed though)

Ya need an Egg-ring.

Custom chainrings up to 110 teeth. They even do oval ones, if that's
your perversion. Not cheap though.

Cheers,

SJS Cycles show TA 135BCD chainrings up to 57t -

With that large a chainring, you will need to remove the RH crank when
packing the Bike Friday in the hard shell case. For that reason I stick with
the 53t big ring on mine - it just fits in the case with the crank in place,
and 53-11 seems a big enough gear on the 451 wheels.

On 2006-03-30, Resound (aka Bruce)
was almost, but not quite, entirely unlike tea:

I saw a beautiful fixie last night at the alleycats.

A front 54 tooth ring, and a back 34 tooth ring. He had trouble with
the threads, ended up brazing the ring onto the hub. "fixed" indeed :)

P.S. It had a lovely basket on the front. :)

P.P.S It was funny watching him spin and still lose big time to
Hannah.

P.P.P.S I found the owner of the Hoffy fixie we saw at the games road
race on Sunday.
