still getting used to new bike only 3rd ride

Hit the Dam this morning for my 3rd outing on my new bike which is going sweet much better than the old Norco. Trying to get used to the gearing as it is a lot different and is bringing me unstuck on the climbs / uphills as i find im either hitting a gear to high or low should only take a couple more rides to figure it out. did to laps and hit a 39 and a 40 hopefully within the next couple of rides i'll be down around 35 - 37 mins
