I’ve lost track of who said it with all these vague assertions, but I’d like to address the idea that curved seat-tubes are not as strong as straight tubes. Like most things frame related, this really depends on the builder. When you bend a tube in this way, the material on one side of the tube is stretched and the material on the other side is compressed. On the stretched side, the wall thins out slightly. Consequently, curved seat tubes need thicker walls (and preferably less pronounced butting) than straight tubes. If your curved tube came from Reynolds/Columbus, it would have been shaped before it was shipped out to the frame builder with this in mind and there’s absolutely no reason for it to be weaker. If the framebuilder shaped it themselves then I agree this would be a concern.

what about crumple zones?

What about them?

When are they?

stop teasing gabes, when we gonna see this beaut built?

It's on it's way to me from Russia as we speak. Should be built next week. Can't f**king wait.

what do you do when you see a spaceman?

...park man.

Gabes are you going to run a disk brake on the front? Do you not think the disc would get smashed up?

Yes, disc brake on front, but with an old rotor bolted to the fork (hence the three eyelets around the dropout), it will work like this:

Lots of people have said this to me. I have as yet not had to straighten a disc, despite running a front and rear! Discs are easy to true up and are great in the wet. More likely to bend a wheel than a disc and at least your braking isn't then affected by the bent rim!

I'm gonna copy this! Brilliant.

does anybody have any old mountain bike spd shoes? been borrowing a guys in cambridge then used my road shoes earlier and it sucked!

i bent my first disc within a month. so i cut out a section of said bent disc and it now acts as a washer under the wheel bolt. works great.

Cambridge now has the latest dead Pompino, crack around the chainstay where the tyre recess is.

does anyone have any recommendations for forks to go with a surly karate monkey

exactly what i was looking for , 22 t freewheels and "booster plate".
but for the last one , can somebody hook me up ? link or for sale ?
thx !

I have one of those, similar to this, just without the cut outs

can deliver at the London Open, with back plate (for track frames), bolts, clips, the whole lot

£15

one question actually : is the booster plate is able to adapt v brakes on race frame ? no cantilever studs just the hole for race brakes.
@rik i m very interested but i need it before the end of the month, i have no problem with shipping.

i m also having problem finding 22teeth freewheel singlespeed around here in toulouse, if by any chance you have one laying around ...

Ouch. Has anyone had a response from them on this issue?

To to establish that that ^^ is a brake mount, a booster is on of these http://www.bikepro.com/products/brakes/brakeboost/boost-jpg/h3h_joes_booster.jpg
