Re: Forum logo (subsilver2)

How do you turn the logo off? Or is it a feature of the style you're using?

Re: Small wheel blowouts - options?

Same reason as why car-bike/pedestrian survival rates in collisions get dramatically worse with car speeds. The kinetic (moving) energy that you're absorbing/dissipating goes with the square of speed. That's roughly why emergency-braking distances also go up dramatically with speed (although there's...

Re: Small wheel blowouts - options?

Thanks, I am supposed to know this stuff, but it's a long time since I studied physics :oops: I did realise that convection was more important anyway. I can't my head round the fact that the tops of the wheels are going through the blocks at the same speed if the rotation rate is higher ...............

Re: SMIDSY vs SMIFY

It's consistent with previous discussions, and with experiences of cyclists who have reported being certain that drivers had seen them, when those drivers then pulled out nonetheless. It seems to me to be quite fundamental in our understanding of the road, and visibility. We forget, I think, when ar...

Re: Small wheel blowouts - options?

I was derided on here for suggesting that black rims retain heat more than silver rims. Black bodies radiate heat faster than white/silver, all other things being equal. They also absorb heat faster, but the heat here is coming from friction, where colour is probably not a significant factor. The h...

Re: Review of Highways Act 1835

In essence there are three types of "footpath", each with its own set of rules. The distinctions can be lost on people: ⋅ Footways that are the part of a highway designated for pedestrians (see above); riding on these is a breach of highway law. Necessarily therefore this applies...

Re: Walking past No Entry Signs

I can think of at least 2 local examples where green lanes, in these cases unclassified roads, pop out into the middle of a village that has 30 mph signs at the point of entry on the only through road that is tarmacked. Motorised vehicles can thus legal reach the middle of the village with no indic...

Re: Go left Young man/woman ......go left.

Ditto Drossal's comment about some of the underpasses but I do think that the original network is fantastic. The problem I described is on the original network. Generally though it is better than the later additions. Even the original, however, tends to stop unpredictably in obscure parks and so on...

Re: wheels, a pair and a single front. FREE

Interested by the Campag, any idea what model it is? (Interested anyway but more likely to use depending on model, so asking in case a better claimant comes along.)

I'm between you and Norwich, may be able to work something out.

Re: Request for help with PhD Research

I would have contributed, BUT "Unfortunately, anyone with a chronic physical health condition, such as heart disease, is not eligible to participate." This seems a little odd to me. I do not suffer from depression, but I do get depressed by failing health (COPD most relevant in context of...

Not directly what you're asking, but try the three categories here for an idea of the range of available replacements.

Re: One solution to tailgating?

Yes, I discussed that once with a former police driving instructor when renewing my minibus permit. Not too long before, I'd had the frightening experience of driving a bus full of Scouts, with a lorry tail-gating me. I was in the inside lane, with nowhere to go. We agreed that the only available re...

Re: Shimano hub cones - common/interchangable?

Baker's Bikes in Bishop's Stortford used to be good for obscure cones, such as 1970s Campag and Shimano ones. Not sure what they can offer now.
