I was forced to try my winterbike for the first time this morning as I broke a spoke on my spare wheel last night, I now have two wheels with broken spoke on my regular bike ( I need to lose some weight). I took about the same time with my winter bike ( and old winterized mtb) than I usualy take with my road bike, I was a bit surprised as I tought that I would be much slower on fat tires but the legs are hurting a bit.
