There is a lot of information out there on improving cycling performance using wider tyres, waxed chains - but for me a lot of it centers around professional riders riding at 30mph, and not the recreational cyclist wanting to improve 15mph to 20mph
I think there is a lot of data out there that can highlight affordable ways to do this - so you dont need top of the range tyres for the 15-20mph shift. Also recreational cyclists arent tied to UCI rules as they arent competitive - so can make changes in this area
Id like to collate this information to help riders at a practical level
