I'm confused. You say CTC have asked you to detail damage to your bike and property
? Surely you mean their solicitor RJW, or not as the case may be. You need to be dealing with a solicitor, not an admin person at the CTC, who can give you their opinion on your case, what the main issues will be, how long it might take and most crucially how much you are likely to get.
WRT to the damage to your bike, get it down to your favoured bike shop and tell them you obviously would like the damage repaired, or if this is not economically viable, a replacement bike of the same spec. Also tell them what clothing was damaged and ask them to quote for replacement. If they charge for the quote so be it, pay it. Get a receipt and a grip and see the bigger picture. You are more than likely going to receive several thousand pounds of compensation. All these questions you are asking would have been covered in the information pack provided by the solicitors or in general discussion with them. Well these issues were when I signed up 10 years ago with CycleAid who advertise in the back of CW.
I would imagine, as liability is not in dispute, that you will get an interim payment from the insurers pretty quickly for the damage to your bike, other property and out of pocket expenses, and maybe any physio costs if you go private, if you have a good solicitor. The insurer shouldn't quibble about wear and tear if it's well maintained bike, you have a good solicitor and as I say there is no dispute in liability as it is simply not worth them doing so. They paid out in full no quibbling on the repairs to my road bike which came to over £2k, also paid for replacement clothing, out of pocket expenses and even a turbo trainer when the doc said I would benefit from one during my convalesence
.
Condor did the repairs as it was one of their Barrachi road bikes. It was still in good nick at 4 years old but they still gave it a full respray, not that it needed it, well it had a few tiny chips in the enamel. But it did look smart after.
I would advise taking your bike to a "proper" bike shop as well, an outfit that can build/repair frames, basically they know what they are doing and they can do it well. You need to take it somewhere that can make sure the bike frame is true, ie not bent and also not cracked.
. Damages should reflect this, that is why they can take a long time to finally arrive.
...sometimes I think a 'clean break' is better than the muscles/tendons taking the strain..... I see far more long term damage in a muscle/joint injury than a clean break.
