Re: Cycle Travel question!

In the Cue sheets in would be useful to know the A/B Number of the Major road one is crossing: this info is already in the on screen panel directions. If it is a question of space, then replace Major with the Axxx/Bxxxx Number and underline or similar to indicate its a major road crossing? Thanks fo...

Chains that adapt tp pin wear?

I wondered if it was possible to make a chain that automatically compensated for pin wear, e.g.: 1) Use elliptical rollers so that they 'find' the right diameter to seat on sprockets as pin wear makes pitch lengthen? 2) Make the rollers wear at same rate as pins: seems unlikely given multiple variab...

Switchless Schmidt E6 Lamp base unit (needs new reflector).

I broke the lens of my E6 while turning my folder in a train vestibule. I have enough other lamps so have no need to replace its lens (spare ones available from sjs for £10 sterling). Own the best halogen filament lamp ever* (is reasonable with some LED bulbs like reflectalite and has a built in hea...

Re: Best Folding Tourer?

why would you choose to use a tool which (if used to make moulton tyres only) might last almost indefinitely, but which would wear out and need replacing ( at a not inconsiderable capital cost) if use to make many more tyres for lots of other bikes? In the process all you might achieve is to create...

Re: Best Folding Tourer?

...Wouldn't the extra profit from selling to others help pay off that investment? ... it also depends who owns the tooling and how much the replacement cost of the tooling is. Tyre moulds are expensive to make and just wear out.... I was presuming they would charge enough to cover their costs and m...

Re: Best Folding Tourer?

...If 16" wheels were a brilliant idea, there'd be more bikes (folding and non-folding) using them. As it is, Brompton 'inherited' its rim and tyre size from the original moulton design (you could buy those parts when the prototypes/early versions were being built), whereas Moulton have -for v...

Re: Derailleur Hanger alignment tool ?

a nutted wheel can exert a much higher clamping force and the end of the axle is much less likely to bend too. You would feel a proper Charlie if you snapped the end of someone's QR skewer.... But I thought it was the derailleur hanger (ie an integral part of the frame) that was being bent: I don;t...

Why plastic rim tape edges not feathered?

Why are plastic rim tape edges not feathered? Surely this is an obvious improvement given that plastic is hard and may cut into the softer tube?

Re: TERN/DAHON Style folders:why fold with chain outside?

Their seems quite a bit of empty space in the middle of such bikes when folded hence I did.t consider that. The kingpin was so bulky avoiding the chain would seem worth it,,, The Dahon curve always seemed to ignore its one inherent advantage over a Brompton (other than price and fat tyres): it has n...

TERN/DAHON Style folders:why fold with chain outside?

TERN/DAHON Style folders: why do they fold with chain outside: surely folding with chain inside would be a large improvement (keeps oily chain of folded bike away from legs/furniture etc).

ie like the Brompton, which if had covered that bit with a patent, said patent will have expired anyway.
