Much of the advance in LED brightness has been from getting the heat out of the chip better which means attaching it to a good thermal mass and radiator. Thermal mass isn't going to affect the steady-state temperature, is it. Mounting the chip facing backwards makes that difficult because a good th...

I would be glad of some guidance, if not legislation, on bicycle lights. It is true they are not as powerful as car headlights, but the radiance of the emitting surface is a lot higher with modern LEDs, to the point where it is almost painful to pass another cyclist with a Magic Shine-style light. F...

I think you'll find our experience of the IRA in the 70s through 90s, and their use of bins as handy places to leave bombs, has something to do with why there aren't any bins on most public transport stations. I hear tourists asking it all the time at Victoria, which, along with Paddington on the s...

I don't suppose any stations have these any more. Like they don't have bins. The upshot is that I'll have to carry a pile of cycling clothes and shoes around with me, whilst dressed up trying to look smart. As it is going to be pouring with rain tomorrow, it will be a steaming and dripping pile of g...

I can't peel myself away.

I thought this was another Jimmy Savile thread.

This 1985 book probably came out too late to help anyone.

You can use "more than half" of 2 shims to avoid a gap....I wouldn't be happy with a big gap in a thick shim..... I was contemplating this this very morning. The problem became more complicated as I thought about it because two halves could easily fall down the seat tube, or become lost w...

I attempt to appear normal when cycling with a purpose, so try to choose clothes that are socially acceptable whilst having the usual quick drying/wind resistant etc properties. Time and time again, I end up buying golfing clothes. Apart from the risk of looking like Ronnie Corbett, the materials an...

There's a long and interesting thread about Karrimor and the event jacket here http://www.outdoorsmagic.com/forum/gear/karrimor--branded-event-waterproof-for-less-than-100/51829.html Apparently the jacket is a climber's fit - a short cut in length, whereas we cyclists benefit from the back being a ...

Sports Direct has Karrimor Event waterproof jackets for £99. They look good, but I noticed that the lips of the waterproof zips didn't meet in places. I held off buying one because I suspected that it was mutton dressed as lamb, like the rest of the stuff they make. But most Goretex jacket makers ar...

If you are measuring +/- 0.2mm the old seat pin must be very oval That was my error guestimate. The pin is even more oval than that, at one point, we measured 35.8mm and 35.0mm at right angles to each other, but this is consistent with the pin being 35.4mm OD. Colin's idea of cutting up the old pin...

Are you sure your friend measured the correct thing? cheers It's definitely over 35mm. I measured it myself using a strip of paper wrapped around the pin, so that the two edges just butted up, then divided the length by pi, and came to 35.4 +/- 0.2mm, then my friend used Mitutoyo digital calipers, ...

I've had a friend apply his digital calipers to my seatpin and, on average it seems to be 35.4mm OD, although it is a bit ovalized in places, eek! I've got two solutions: Buy a 34.9mm seatpin, but I would then need a 0.2-0.3mm shim. Is there anything lying around a typical house that would do that? ...

Given the ability of a beautiful woman to grab my attention to the point of feeling giddy, even when initially glimpsed out of the corner of my eye, and without her wearing hi-viz or a flashing lamp, perhaps cycle tops should have a pretty face on the back of them? Is this why cyclists with mirrors ...
