Re: Why isn't there a cycles on trains campaigns from Cycling UK?

I suspect it might help towards such a policy if we cyclists were clearer about quite what we wanted. Yes, this is a good point. I can't speak for everyone, but I'll set out below what I would like to see. I've divided this up according to the type of rail route: commuter routes, fast inter-city se...

Re: Gerard Vroomen on the future of bicycle tech

I've been thinking a bit about some of the developments that have been discussed here, and whether they represent an improvement or not. 1x drivetrains From a logical point of view, there is usually little reason not to want a front derailer - they cause no inefficiency, don't weigh too much etc. Bu...

Re: Continental-style traffic light junctions

One limitation is that that long wait will require a substantial reservoir for cyclists to wait to be allowed to cross. Only very large junctions are likely to have the space. Ideally these should have over/underpasses of good standard. For more "common or garden" junctions the continenta...

Re: Monoforks

In some case "rigid" forks have a certain amount of flex designed into them to give a more comfy ride, don't they? Perhaps it is harder to have this desirable flex without having undesirable flex when you have a monofork?

Re: Disallow bans of only cyclists from (previously) all-purpose roads:only allow ban of same list of vehicles as for M-

It's junctions that are the problem though. That's where most bike accidents happen anyway, and it's easy to design paths such that junctions are harder to handle for cyclists and motorists alike, and therefore the road is more dangerous than it was without the path. In urban areas this is certainl...

Re: Why isn't there a cycles on trains campaigns from Cycling UK?

Loco-haulage offers: ... - marketing appeal: some potential passengers regard loco-hauled sets as higher status or as 'proper trains' and are more likely to use them when an MU would have them sticking to their cars. Similarly enthusiasts tend to like them and may deliberately pick routes or times ...

Re: Continental-style traffic light junctions

The history of traffic engineering in the UK has been based on paint in the form of GIVE WAY lines wherever possible. Are you saying that fewer junctions in the UK are signalised than elsewhere? Compared to the USA that may well be so, but I'm not sure if there is any big difference compared to con...

Re: Continental-style traffic light junctions

Hello everyone Some interesting points so far. If possible, I'd like to concentrate on discussing signal-controlled junctions, rather than drifting too far into the merits of strict liability. I'd like to expand on my original post: 1. Signal-controlled and give-way junctions are two different thing...

Continental-style traffic light junctions

Roger Geffen has written the following blog post: https://www.cyclinguk.org/blog/consistent-cycle-friendly-design-standards-consistently-applied-why-wouldnt-you There is lots of good stuff in here which I strongly agree with. However, one thing which I am not sure about, is the suggestion that we sh...

Re: How did we delude ourselves about 23mm?

MickF, I do I recall you saying somewhere else that you prefer quite a slow cadence? Perhaps this is why you have no problem with narrow tyres. Slow cadence = more force on pedals = less weight on saddle and hands perhaps? I guess the legs are quite good at responding efficiently to vibration, rathe...

Re: Why don't more people use recumbents?

I've just ploughed my way through this rather lengthy discussion! There is one new point I'd like to add. What about "would-be" keen cyclists? My suspicion is that there could be quite a number of people out there who would be keen long-distance cyclists, but they just find it too uncomfor...

Re: Supercommuter?

I like how every aspect of this bicycle has been carefully thought through for its intended use. Chain tubes are sometimes used on recumbents to separate rider and chain. Do you think that using some chain tube to protect the chain as it goes past the rear tyre could be a good idea on a bike like th...

Lower gears on tandem - asymmetric q-factor?

I would like to find a way to get some lower gears on a Pashley tandem. Currently it has 38-52 chainrings, and a 14-28 5-speed freewheel, which can be a bit of a struggle in hilly Herefordshire! It has friction shifters and crossover drive. We use plain pedals. If possible I'd like to do this withou...

I agree with everything Bmblbzz said. Tractors and bicycles are two very different vehicles, with different requirements. Does it make sense for them to be required to be always bundled together? Perhaps in some cases it is appropriate to combine them, but in other cases not. On a slight tangent, I ...
