Functional bikes. Not Porn not Anti

If i've got a standard road chainset (shimano 600 42/53) and a short cage rear derailleur (8s) what's the biggest tooth count I can get on the back?

What mech is it? I seem to think the older ones were a bit more forgiving with tooth count, but one would assume up to 28 would be fine.

Depends on more variables than that. Conservatively, without knowing more, 28t.

This cool, any more info?

Reminds me of something I build a few years ago:

how can brakes be functional if they no exist?

Coaster brake

That reminds me I have a brand new never fitted coaster hub in my desk drawer at work.

Anyone want it for cheaps?

Its an old tricolor shimano 600.

Ah, 28 then! I think they can be pushed to a bit more but shifting might be compromised.

My bad, I didn't really get your definition of "functional" !

Think a 26" Surly Disc Trucker fork is available after market, sounds perfect to me.

Thanks!

what are the wheels & tyres on that serotta? still my favourite ever forum bike

Whoaaaa...going on the Surly site brings a whole new perspective!

@edscoble 430mm if I've measured correctly. What do you have in mind?

I've got a Raleigh Dyna-Tech with this years Shimano 105 group set and some Mavics, I'll get a photo for you when I get my arse out of bed.

We get it. You love 650b.

Nice! Are those dynatech's flexy?

Spent the afternoon making my girlfriend's mixte even more functional. The surly racks are beasty!

I'd love to try out one of surly's big dummies. I have no idea what I would use one for though.

No, not for me at least, I only weigh 10 stone / 65 kg, the fork flexes a little through braking, and the stem flexes, which I'd expect.

If you want to talk about flex, the original wheels, now they were flex.
