The pro gold arrived today, cleaned the chain and applied it, lots of black crud came out, did it again and it cleaned up so I wiped the chain cleaned and applied a little more gold and it now looks clean and silky smooth.
While doing that I fitted a small cheap Shimano computer, anyone tells you it`s easy trying to find a spot where you can maintain the 5mm between sensor and magnet on a front suspension fork where you have purpose made brackets for the mudguards stays hasn`t done it
Anyway, all installed and running fine, now all I need is some decent weather to start breaking my Brooks saddle in
Thanks for all your helpful advice.
