Range difference between AT and 107mm (38T gear) on a GT

Does any know the approx. difference in range and speed between All Terrain tires and Abec 107s with the 38T gear? I know there are a lot of variables on this. This can based on fairly flat travel with a 175 lb rider. I have a 2 in 1 set-up on my Bamboo GT, but have only used the AT wheels. I just like them. I'd like more range, but want a larger, more forgiving wheel. I'm wondering if the 107mm would be worth the investment. It get's expensive when you add up the wheels, gears, belts (assuming need a new size) and belt guards.

Thanks,
Marc

 

Well I'll reply to my own post now.....I purchased the 107s and just put them on. I have the R1 remote, so there's no setting for my 107s with 32T gear. I'll use the 97mm 32T setting and figure my speed and range to be about 10% more than the remote reads. I'll give this a test ride and post back the results......

 

How did it go?
