My Trek is the 3400 - nice sensible road bike. Looks very similar to
that, but without the chain guard. Doesn't have all that dodgy brake
stuff, either. A reasonably heavy stop (say from 20mph in 5 seconds)
only needs to dissipate 3kJ at 600W, which is no problem at all to
dissipate in a pair of wheel rims.

Those brakes aren't dodgy, Don, they're hyper-competent; what I forgot
to add is that they have a built-in modulator. They stop the one-
eighth of a ton of me and the bike and light touring gear from thirty
kph in 11 feet. I know, because I chewed up a pair of tyres while I
practiced that one to perfection. But I agree with you, for casual use
those roller brakes are overkill.


I'm a great fan of "keep it simple" for things like bikes.


Me too - thumb the starter, hook a gear, give it a *big handful* and
realise, moments later, the flickering in the corner of your left eye is
the *traffic* on the inside lane...

I can take my bike places you can't take yours ;-)

Here's No. 2 son on my bike - all ginger and cautious; it was his first
time back on one in a couple of years and was doubtless fearful of a
'low speed drop' !!

That sort of riding looked like a guaranteed way to have a low speed
drop. I imagine he's a bit more fluent now?
