I've got a 120mm 26er HT singlespeed @ 36:19. I ride around Marsden into Wessenden and the North Peak. I plan on riding in the Dales soon though.
I am 19 and 6ft1 @ 11.5 stone so not a fat biffer.
I am no longer enjoying the hills, as I just get tired and the ride becomes a slog. Also on muddy terrain or technical climbs the rear wheel slips as I stamp on the pedals.
Do I just need a lower gear, or should I go 1x9 (I've got a 9 speed shifter and mech)
