I was never a standing climber, always seated in granny gear. This season I decided I would do a lot more standing for fitness and alleviate some knee issues. Coming off winter I had no traction issues. Now that the dirt is dry / loose I am breaking traction on standing climbs. Not sure if it is par for the course or my tire is lacking. I am running a Maxxis Ardent 2.25" rear tire. I have always thought ramped knobs were good for rolling resistance but maybe hurting the climbs? Thanks.
