• I doubt that they would be vastly better in the wet. After all, even on flattish TTs on the TdF in the rain the riders all go for fully geared rigs and we know that at least some of them are excellent fixed riders.

    Is suspect that the majority of the reason for them being winter trainers is, as stated, the shorter training times and the lower susceptibility to mechanical failure. The only moving parts in the drive train are reduced to some sealable hubs and bottom bracket at the chain. However, I'm inexperienced enough to not really have been tested on fixed in comparison to geared (where I've taken most punishments available).

    Only posted the above article because it talks about the extreme end of winter conditions.
