Any question answered...

There's your trouble. It's easy to apply too much torque by rotafixing,

so what is the point of the rotafix method? Obviously I should have done more research on it, but seems easy to be led astray by twats like this http://204.73.203.34/fisso/eng/schpignone.htm

So that's 2 wheels fucked and £130+ up the wall

it's really good at getting sprockets off.

thats the reverse rotafix

I use it because I'm fed up of breaking chain whips.

Get the DA chainwhip, 'tis v.good.

You don't need any tools to put the sprocket on; leg power does the job. Why would you ever want it on any tighter than you can do it by pedalling?

I find cycling up a biggish hill does a good job, but if you are in a workshop then a tool is more convenient.

No, the method you described sounds reasonable I wasn't aware of it, nor wanting massive tightness. I installed the 1st sprocket with a whip, but found it slipped after a few months. A few searches led me to believe rotafixing it would sort it. I'm annoyed it was shit advice, that's cost me 1 maybe 2 wheels now.

Anyone know of a decent place to eat out in crewe?

No, sorry

no decent places or you don't know?

If there were any decent places, maxcrewe would know them.

Oh of course, silly me, there's always Herpy Derp's Herpsquerp Palace, on Derpington St

Great place

I've done a couple up with a chain whip then I guess leg power would have tightened them further if possible. And then they came undone during polo. I also stripped the lock-ring thread at the same time.

How come the numbers on a phone start with 1,2,3 on the top row, and going downwards, and its the opposite way on a calculator?

what kind of bar ends to people normally use with cut down risers?

I use the plastic ones that come with the grips i use (the genetic ones, cheap and excellent) I dont really rest my bike on he bars so they do the job perfectly, if i had a trick bike i'd get metal ones.

Mine don't fit in the bars. I had a pair before I literally hammered some Fizik bar ends in, so I'll do that again if needbe. I was just wandering what other people did.

I usually use grips with closed ends on risers

If i use closed end ones i still put something in the bar ends because i've found if you don't ans you drop them the bars can cut though the rubber

That's the trouble with using something designed for track racing on trick cycling bikes. At some point the lock ring is going to come under pressure, and once the sprocket is on the move it has a huge mechanical advantage to drive the lock ring off by shearing the threads; one or other of the equally fine pitched threads is going to have to give if you don't get your legs out of the way. The repeated high back torque involved in trick cycling tends to open up a gap for everything to go wrong into; threaded couplings will always loosen off if there some radial shaking.

Fundamentally, threaded sprockets are not actually a good design, they work just well enough when well made and used within the performance envelope envisaged by the original designer, but they are marginal and low ratio gearing or poorly matched tolerances will fuck them up. Fortunately, bolt-on sprockets are now widely available.

I see. I didn't know about these bolt on sprockets before. I think I will have to invest before I wreck another perfectly good hub :) Cheers once again J.

The best option is to NOT cut off the ends of your grips, you muppet! :-)

shut it Mr. Sensible.

Henry, you had perfectly good grip and yet you decided to put them back to front.
Aren't Condor grips sealed at the end like Soyo?
