@horizon, about 5 11, and it's the 58S frame. increasing the seat height feels like it's ironed the problem out.
@triasthete, the brake cables themselves are fine, it's the little QR stopper thing that rattles, and only when I apply the brakes (both sides). When at rest the QR stopper is in contact with the hood, so silent. It is wierd, as the other set of the same levers I have on the LHT are fine. I was thinking of some clear glue or trying to wedge a tiny piece of plastic into there.
I'll try with the tyre pressure, good suggestion; they came at 75PSI. Yes, I've read that friction shifting on 10-speed is finnicky. At the moment indexed shifting works, and doesn't stop me riding, so I'm just going to live with it. I really was surprised how 'positive' the shifting feels though.
Why not a frame only? Well, in retrospect I should have. If the opinion (eg John's) is 'stop talking about it and get out and ride it', well I disagree. Logically that implies that people shouldn't expect a Thorn bike to fit, out of the box. And that then implies that Thorn's whole measuring requirement is just a rouse to make people feel like they're getting something more than just an off-the-peg bike. I don't believe this is what Thorn is about, I still believe they are about getting you a great fit, on top of a great bike.
The Thorn 'product' (so far as complete bikes is concerned) is bike + measurement = fitted bike. I've been riding a too-large bike for years, finally investing in a bike that really fits is a large part of why I went for the complete bike. It cost me £150 in travel and two days, to visit Bridgwater to be measured. And for what? It was obvious the frame size would be a 58S, but bar height, saddle position, etc, etc. Visiting them was part curiousity, but part getting exactly the right measurements instead of messing it up myself.
If I'd been able to order a 58S off-the-peg I would have expected to have to shuffle things around until I felt 'right'. But Thorn sell fitted bikes, and they sell that expectation too; and you can't order without supplying the measurements. Something went wrong with the setup on my bike, which meant that physically things were in the wrong place, and it felt awful. Saying, 'just ride it anyway,' doesn't help because anyone else thinking of buying a fitted bike could take the impression that the resulting bike might or might not fit you. Something went wrong with my particular bike build, and I think it's right to be annoyed about it as that is part of what I've paid for. Though I don't think it's typical of the Thorn service, if it was I wouldn't be annoyed about it.
I wrapped the replacement bars in fresh bar tape last night, so me and the bike bonded a little
cheers,
