Often frowned upon I know but I am seriusly considering changing from a double to a triple 105 chainset and mech.I am new to cycling(6 months) and am really struggling with hills generally.I am 6'2" and weigh 13 1/2 stone and am riding a Trek Madone 4.5.I am cycling 100 miles per week but still find hills a real struggle to the point where I often have stop and either push or take a good long breather.On advise from my LBS I am thinking of making life a bit easier for myself and going triple.I have tried a different rear cassette(ultegra 28) but that hasn't helped much.I recently did the Circuit of the Cotswolds and spent most of my time walking the big hills(not on my own I hasten to add!).
Anyway just looking for thoughts and pros/cons before I make the move.
