Thanks all for your suggestions!
@Cyclebum, I tilted my shifters and brakes around the bar to change wrist angle early on, and that did make a difference.
@BigAura, thanks for the link, seeing the nerves makes a difference, I will know better how to deal with it.
@seeker333, Havent seen a bike shop out here, and all the bikes I see are old Chinese bikes, and their headstems will not attach to a LHT without welding. Further, most bike shops in China sell bikes. Maybe helmets, maybe maybe gloves. Tools? nope. Parts? nope.
@Chris Pringle, Brooks is now 15,000 km old, little polish left on it. I think it is set up as well as I can get it. I travelled with the allen keys for adjusting it in my handlebar bag for the first week and kept tweaking it. It is as far back as it can go. Yep, nobody here would be able to fit it for me.
@Carbonfibreboy, I have two pair of gloves, and I scoured Chengdu (a city of 11 million) for good bike gloves and couldnt find much. The pair I have are not bad but dont have much padding.
Will have a day off today, then put my foot down for 700 km to get to Kashgar where I am told there is a decent bike shop. Nobody there will be that good at fitting bikes to people, and they probably wont have better gloves than I have. However, there should be a large number of experienced bike tourists there, going both ways along the Silk Road, and I might be able to get some help. I will have at least a week off there as my Kyrgyzstan visa doesnt start until Aug 27.
Thanks for all your help
