Last nights 10 saw me net 27.09. I'm now thinking that it's time to jump up a chainring. I'm currently on 46x 16 giving me a GI of 75.6. I'm over spun on the short descents that I have and am spinning pretty hard on on the flats. A quick calculation says that I'm currently getting an average of 100rpm throughout. I don't think I'll improve much on what I'm doing so here's the question.
Do I go to a 48 front chainring for a 78.8 GI where I'll still have to still spin at 100 rpm to get a 25 or do I go higher and ease off on the spin. The 10 course in question has 1 soft descent of about 1/2 mile, two short sharp climbs to roundabouts with short sharp offs and two soft climbs to roundabouts with soft offs (I can currently keep pressure on the soft offs but find it hard on the second short sharp off).
Opinions please.
