Re: This will revolutionise shifting... or not...

The No U-Turn from M5 (recumbents) tackles the same qyestion; possibly better...?

Re: 8 speed chainring: 9speed chain

Thank you both. Plan A:- I've got eight speed chains (and cassettes) for other bikes in the family. Having offered up one of them to my cassette and derailleur, I think that it's a definite maybe. Plan B:- If not, i'll try the empirical approach; it may turn out to be error and trial. Plan B.1:- Oth...

Re: 8 speed chainring: 9speed chain

Thanks! I am aware that I'm dealing wih an ancient design,but; I first used a bushless chain with six speed friction shifting in the eighties. Therefore, I'm used to not having inedxed gears. Recently the indexing became unreliable (sometimes not changing gear at all) so I reverted to friction gear ...

Re: Downtube bosses - a unique arrangement?

Suntour used to make a pair of downtube levers that were on the same bracket that bolted onto a boss brazed on the top of the downtube, similarly to the photo. But that was a long time ago....!

Re: mudguards are back in fashion

It would contravene the techical regulation for fairings. Even if legal it would need to be inspected and approved.

Re: Mount that allows front lamp to tilt on the go (dipped versus full beam)

The Busch & Mueller IQ Fly dynamo lamp is adjustable for angle. The lamp itself pivots up and down in its housing. However, it's a bit bulky (taller than many dynamo lights) and at 40 lux, not the brightest. I found it to be an adequate light most of the time, but a bit short in reach for fast r...

Re: QR Saddle bag

You certainly can use a traditional saddlebag oo an SQR frame.
I have a Super C bag mounted on one, and an SQR Slim bag for smaller loads.
It's best to make sure that there's enough room to fit/remove the bag before you commit yourself! If it fits, it works well.

Re: DIY recumbent bike....?

Fair enough.
I recognise the feeling. I have a recumbent frame, but I also have a very nice diamond frame, made of metal, bike with lots of spokes and not too many gears. I ride the second bike...

Re: The whole CO2 inflator thing

Bamboo yarn is man- made fron a viscose fibre that uses bamboo as the feedstock instead of wood.

It is very comfortable to wear, I think more so than polyester or polypropylene.
