climbed off once on Cheddar dammit
Person in front of me suddenly ground to a halt on a particularly steep switchback bit and I had to stop .
Because I struggle so much on hilly bits I have developed a few techniques to help me get up without climbing off.
I use a 38t small ring which few people realise can be fitted to a standard crankset instead of a 39t .Gives me a tiny edge and vanity won't let me fit anything bigger than a 27t cassette sprocket.
Also when I'm out of the saddle and at my limit I change my pedal stroke. I pull only for 10 revolutions then I push only for the next 10x .
Believe it or not it is just enough to allow one set of muscles a short recovery period.
When really desperate I have been known to weave from one side of the road to the other and back which lessens the gradient. Bit hairy on open roads though
