Any question answered...

One could, although it's not clear why one would want to. If anything, it's easier than a normal coaster brake, since all you have to do is use the reverse torque to actuate the brake. Any mechanical or hydraulic method would involve a fair amount of backlash, but you could eliminate that for all practical purposes (i.e. the actuation backlash would be less than the inherent backlash in a roller chain drive) by using a load cell to detect reverse torque and electrically actuated brakes.

Seems like the best option...

Thanks Mr Chalfie Sir - seems like the best value for money too.

Cheers - this did it in the end - having the chain fairly tight already was limiting my ability to do this.

I had already decided any future 1.8" chains I get will be wipperman, this has now cemented it.

Any tips on best places to buy Wipperman chains?

DELETED (getting my chain link types mixed up)

The 1 1/8" steel steerer on a bike I'm building is slightly oversize: the bearing top cap is a very tight fit and the stem would need to be prised open.

So even if I got everything on, I wouldn't have any pre-load adjustment.

Any options apart from wanking the steerer with a piece of Emery cloth?

Ream the bearing cover and use the old "screw in from the wrong side against a penny" trick we know and hate from closed stem handlebar clamps to keep the stem free sliding while you dial in the prelaod.

I find bicycle shops to be the best source for the ½"×⅛" ones, anything bigger and you'll want an industrial drives shop.

You've quoted me out of context, goddammit!

But thank you, that sounds like a lot less work.

The penny that is, not the wanking.

Integrated headsets. 1 1/8.

Are they all much of a muchness?

I need one to go in here and don't want to spend more than 15 quid.

Are they all much of a muchness?

Yes, in the sense that >90% of them use TH bearing cartridges, and the rest is hard to get wrong. There are 2 different common bearing diameters, so you need the right one, and it would be nice to have the bearing thickness the same as what the frame builder anticipated for aesthetic rather than functional reasons.

first, is there a headset thread in the mechanics and fixing forum, if so can;t find it.

Second, is there a solution to threaded steerer being 3-4 mm too short for a headset. Have fitted a shimano 600 headset to new frame but there's not much thread for the top nut. Are there headsets which take up less steerer, therefore leaving more thread at the top?

From what I can find on old adverts, this lovely frame should have shipped with an orbit CE.

That seems pretty standard.

Edit: why do I need to know the bearing diameter?

Tange Passage is meant to have a pretty low stack height.

Because a 41.8mm peg won't go in a 41.0mm hole

Cheers @mdcc_tester, no such problems on the clutched X9. Straight swap-out.

Travellers. How do you get rid of these fuckers? A group have moved onto a plot of land awaiting development at the back of our garden and have already started chucking shit into our garden. I now how 7 bikes, 3 scooters and everything else from the shed inside our house.

They have several generators running, their kids running around screaming until God knows when it's a total fucking nightmare. Police says nothing can be done even though it is private land and they had to take down fences to access it. How is that even legal?

Landowner needs to report and evict them I guess.

Anyone know of a trustworthy bike shop that has the tools to extend the thread on a fork steerer? Winston is reticent to do it, as his tool isn't sharp enough.

Edit- in or near SE London preferably but can travel!

It seems like they are breaking a few of those laws already. The school inform me the police and local councillors are onto it. In the meantime I am retaliating by chucking back the stuff they throw over. They better be careful as they have some very expensive cars there. How they afford 100K AMG Mercedes is something I'd like to know

I have a tentative OK to do that for a fork from Rat Race cycles in Nunhead. Worth giving Pete a bell.

Not paying council tax, income tax, tax, tax, tax

Thanks, will do
