Rash; Well I went on a bike maint course a few ago. Cleaning the bike last week, I believed that the teeth on the chainset were / are? worn. So 2 days ago decided to buy a new chain ring to find that the complete chainset was not much more. So, with
ribble doing a deal, I ordered a new chainset; a lovely Ultegra SL. Anyway, the rash bit. It arrived tonight and I compared it with the current one and noticed that the wave effect was not wear but part of the teeth design. Problem - even my wife noticed that the 2 looked the same - poo.
