Going faster

Epetruk

Dear Urcers,

A few days ago, I took my bike into the shop because I had had an accident
which bent the forks. I was able to get the forks replaced, but the guy who
replaced it told me he had made an adjustment to the bike in addition.

I didn't quite catch what he said, but when I took the bike for a spin the
next day, I found that whatever he had done, the bike was now *flying*! It
seems it I could turn the cranks with a lot more ease. I could do 20mph
without too much difficulty - and I don't even use SPDs!

I went back to the shop the day after that to find out what magic had been
wrought on my bike. Unfortunately, the person who did the actual repair
wasn't there, but a colleague of his said that he probably must have
tightened the gear cables.

This sounds a bit odd to me - I can't see how tightening the gear cables
would make turning the cranks more difficult. Anyone else have any idea what
else might have been done?

Yours sincerely,

Added wings?

He arranged a tailwind? Put a second computer magnet on the wheel? ;-)

Never believe anything until it has been officially denied.

Fitted a second magnet?

You are right to question what good "tightening gear cables" would
have done, it's bloody nonsense. That answer is also a reason not to
entirely trust the shop for future mechanical work. You know for sure
they have at least one clueless muppet working there. Hopefully they
don't let him near the spanners.

There really aren't many small tweaks that will give a bike a
genuinely significant boost in performance. The most obvious would be
re-adjusting the brakes, if the pads were rubbing on the rims.

Servicing poorly hub bearings is noticeable, but he's unlikely to have
done that for you as a quick freebie. Same with a bottom
bracket/drivetrain overhaul.

You say you had the forks changed, did you swap suspension forks for
rigid? That would give a speed boost on tarmac.

Other than that, I'd suggest it was just perhaps a combination of the
bike feeling a bit "fresher", because you'd had it fettled, and maybe
an unnoticed tail wind or even just good strong legs today.

I dunno, but I wish my bike could be made to go faster with just some minor
mechanical adjustment

Locknuts on a hubs were not locking and had auto tightened to bind the
bearings?

Reconfiguration of the Engine Management System, have you any recollection
of being hit on the head with a mallet? :-)

The mythical bike mechanic.

Just a guess obviously, but aligning a wheel that was rubbing on the
frame, or stopping the brakes binding on the rims, would be possibilities.

Could have readjusted a conventional BB that was too tight, or just put
more air in the tyres.

Good call, more air sounds very likely.
Before the last ride on my winter bike that's exactly what I did, the tyres
were seriously underinflated, and although I wasn't aware of riding faster
(no computer on that bike) I was fairly convinced I was using higher gears
for the same route, subjective I know.
The ride was a little harsher but hardly detectable on the smoothest
surfaces.
(On my shiney summer bike I check pressures before each ride, on the winter
bike I just get on and pedal).

Zog, you're right. I finally sussed it today when I noticed that my rides
were now 'bumpier' than usual... checked to see if there was a potential
flat and the tyre was hard as stone.

So I should be looking to get my self a decent track pump with which I can
easily achieve the same tyre pressure in the future. Any recommendations?

That's easily done. Just neglect your bike for a year or two, then you'll be
impressed how much better it is after minor fettling.
