I live in the Cotswolds which as everyone knows are a bit up and down. I have a 700c Hybrid which i dig out of the shed on occasion and cycle the ten miles to work. I would love to get there in a reasonable time not knackered and not sweaty. So to that end I am looking for a low cost reasonable retro fit kit which I can try out without breaking the bank. if it pans out I will invest in something better. looking forward to picking some brains and indulging in jovial banter.
