Any question answered...

You might have a fixed/fixed hub since you can always pop a freewheel on a fixed thread.
But unlikely.

Why not buy a nice new hub and learn a little wheel-building!

It probably isn't best practice but I bought a (fixed-fixed) hub from On-one for £15 and just reused my spokes.
So a fresh-ish wheel cost me £15 plus a spoke key and some rim tape.

damo, how wide is the bar and is it o/s or non? I've got one lying around, sans lever, and if they match up would be happy to swap.

How come a lot of road brake blocks have a little flicky-outy bit underneath?

I believe they're to guide the wheel into place in the case of a hasty/inattentive change.

Ah, I always thought they were for aiding in set up... learn something new every day.

I don't really have a clue, there is just as much chance of you being right as there is me.

So you have something to push against to get the worn pad out?

where's mdcc when you need him!

On my way home from work.

The triangular projection under the brake shoe is a wheel guide, as previously stated. They used to be separate and sandwiched between brake shoe and arm, e.g. part 9 here

And on shoeless blocks they are often mouled into the rubber of the pad

I have a fixed/free hub. I never use a freewheel and have just threaded the fixed side (twat). Can it be rescued or do I have to buy a new hub/wheel?

Ahem Help please oh wise one...

If you mean you've cross threaded or stripped either the sprocket or lockring thread on the fixed side, the only use you have for it is as a suicide hub. If you have two brakes, there is no serious problem with using a suicide hub for normal riding.

yay winner!

Shit.

Thanks anyway mdcc, I was secretly hoping for some miraculous solution that didn't involve purchasing a new hub/wheel.

Anyone know where I can get a cheap BMC frame in size Large?

Mystery solved!

It was Charly Wegelius and Tom Southam at the 2005 Worlds in Madrid. They rode for the Italians, who allegedly paid them rather well for their services.

There was no penalty imposed during the race, but afterwards there were repercussions within British Cycling which saw them banned from riding for their country again and then team manager John Herety lost his job.

Answers questions that hadn't even properly formed in my head.

That's freaky - just spent 5 mins doing some of my finest work in MS Paint just to ask the same question...

Guess I can cut them off then.

why would you cut them off!?

To save weight.

:-)

why would you cut them off‽

Interrobang

Even I wouldn't cut those off.

My question:

My crank magnet (for the cadence sensor) will no longer fit between the crank and the chainstay.

Is there a magnet designed for this eventuality, or should I just cut down the plastic housing on the magnet that I have, and trust to the power of strong adhesive to hold it in place?

I've got a magnet glued (araldite I think it was) to the inside of my crank. Has stuck around for the last 18 months without any problems.

I use a ½" diameter x ⅛" Neodymium magnet attached to the end of the pedal spindle, it is then effectively semi-recessed in to the back of the crank and has enough magnetic flux to trigger the cadence pick up from a fair distance away.

Did you glue it in there, or does it stay in, attached to the pedal spindle via a mysterious force?

As long as you have steel pedal spindles, the mysterious force holds it in there pretty firmly.

Bonza, I do indeed have steel rather than titanium, just in case I gain 20kg overnight.
