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...

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

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 ...

Re: Dynamo Lighting - fit and forget?

Unless it's changed in the last few years - In Germany dynamos are required on all cycles other than racing ones weighing less than 11kg and these can use battery lights which have to be carried if not fitted The law has changed! I remember hearing it on the local radio station when I was visiting ...

Re: Bent Seat Options?

Here is the price list:

http://www.novosport.de/files/9/sitze-polster.pdf

I got the "Liegeradsitz, glasfaser". (Recumbent seat, fibreglass). The first one on the list. I think it was reduced to €100 because of the cosmetic defects (which can hardly be seen).

Re: Bent Seat Options?

I bought one directly from Novosport. They had one with slight cosmetic defects, so it was a reduced price. On a related note, I have been wondering how many different hard shell seats are out there. I think it may be less than might be supposed, because Novosport supply seats to lots of bike manufa...

Re: front panniers suspension forks

Here is a frame-mounted rack: https://www.dutchbikebits.com/steco-headtube-mounting-rack I guess on most MTBs the handlebars are fairly low so you won't have space to put loads of stuff on it. It is quite heavy, but nice and strong (weight limit is 15 kg, not 10 kg). Probably not what you are lookin...

Re: 25mm tyres

Brucey's post sparked off a few thoughts in my head: 1. Jan Heine and Bicycle Quarterly think that roll-down tests are much more realistic than tests on drums, and base a lot of their ideas on these tests. But... they're not pedaling, so if Brucey is right, these are still not very realistic tests. ...

Re: Is time trialling to be banned on dual carriageways (A63)

Just to clarify any confusion, I am quite opposed to any ban on cycling where there is not a good alternative route. By "good", I mean a route which is direct, pleasant to use, and conducive to fast and efficient cycling. Where such routes exist, the fact that one may be banned from cyclin...

Re: Is time trialling to be banned on dual carriageways (A63)

I see that there is quite a strong "thin end of the wedge" argument in this discussion and also in the C-UK response. I would be interested to know: 1. How big a wedge people have in mind. (I.e. cycling being banned from entire strategic road network, or on all A roads etc.) 2. What it is ...

Re: Is time trialling to be banned on dual carriageways (A63)

Personally, I would not at all be negatively affected if cycling were banned on all 70 mph dual carriageways, since I would never cycle on this kind of road. Such a ban could possibly even be a good thing. Some years ago, cycling was banned on the A90 just outside Edinburgh. The alternative path was...

Re: Dynamo system choices

What about a 1.5W bottle dynamo? If 3W gives an adequate amount of light for town riding using incandescent bulbs, surely 1.5W ought to be more than enough for town riding with LEDs. I know that 1.5W hub dynamos exist, but I haven't heard of a 1.5W bottle dynamo. I agree that the noise of a bottle d...
