I'm not too keen on using p-clamps down on the chain stays. I did see something on touringstore.com, something from Tubus I think.


It is hard to go too low when it comes to gearing. Better to have a granny gear in reserve for that inevitable day when you will be riding into headwinds, or climbing steep hills.
