Re: Brompton-esque build; guess the weight

Vindicated! (As is Natural Ankling of course :mrgreen: ) Brompton Marathons are ~420g/tyre; the Marathon Racers are ~280g/tyre, and the bling tanwall Schwalbe Ones are ~173g/tyre. I don't know if anyone makes ultralight inner tubes (latex or otherwise) in Brompton sizes, but you could easily shave n...

Re: Brompton-esque build; guess the weight

A standard S2L-X is 10.2 kg. Depending on what the wheels are they may not save much over the stock - indeed lots of custom wheels (silly deep carbon etc.) are a fair bit heavier - and the Brompton chainset isn't too bad (apparently a Ti BB is a better way to save weight). With the heavier saddle an...

Re: Folding bikes - good Brompton alternatives?

Like Horizon I can take or leave the electric assist, but I think the GSD is great, and just the kind of thing that could replace a second (or even a first?) car for lots of city dwellers. OTOH even by cargo bike standards it's not cheap, and I'd only buy one from a specialist bike shop who knew wha...

Re: Whatever happened to bamboo clothing

Often sold as Tencel or Lyocell, which are cellulose polymer fibres - AIUI the raw feedstock can come from wood or bamboo pulp. Tends to be marketed as 'bamboo' by brands wanting to project an eco-friendly image.

Re: Folding bikes - good Brompton alternatives?

As mentioned above, folders add one more big factor to the normal compromises that accompany any bike design; working out what your use case is going to be is key. Most folders/travel bikes use a variety of non-standard parts and are built in small numbers, so are usually fairly expensive; Bromptons...

Re: Vintage Bicycle Advertisements; good, bad. ugly...

Looking at the text running up the left-hand bottom side of both posters it's the same printer (and therefore possibly the same artist - I presume these were litho printed) for both? Certainly the facial features are very similar.

Re: Carradice bagman dimensions

Assuming you mean the Bagman QR, on mine the adaptor zip tie channels are 117 mm apart c-to-c, and are sized to take a 6mm zip tie.

Re: Vintage Bicycle Advertisements; good, bad. ugly...

Clearly a case of to much advocaat in this Dutch advert Google Translate: "Whoever buys a Fongers saves on expensive repair bills and therefore drives (rides?) well". Not sure modern marketing would allow the linking of the name to a picture of a badly-broken bicycle, however, for fear of...

my knowledge of classical mythology is not vast by any means, but I think this may be Hermes, deciding that he no longer needs winged feet, now he has a nice Bianchi bicycle instead. https://pipegang.files.wordpress.com/2009/11/cicli_bianchi.jpg I like the use of the crossbar for caduceus storage; ...

IME they work well enough - my bakfiets has IM80s (I think?), and they're ok on hills. Anticipatory braking is advisable if heavily loaded, mind.

Re: Cycling London to Amsterdam

I did London-Harwich last summer using cycle.travel's route, which worked pretty well. I didn't have a GPS, but printed off the cycle.travel route maps (and cue sheets for the tricky bits) - I did use my phone to help escape the twisty maze of Chelmsford. The route's roughly NCR 13 to South Hornchur...

Re: Things we need not invented yet

the solution is simple; just use a carabiner to clip your keys onto; the bike lock key can easily be kept this way. FWIW some (a few) models of this sort of lock allow you to ride with the key out of the lock. I don't remember which though. cheers I keep my house keys in a leather key case, and hav...
