I too have read this claim, but I also have "seat of pants" data to support this claim. My FWD bike is much better climbing hills than my lwb TE clone. Granted, there is a weigh difference between the two, but I believe the more closed position that the FWD bike gives allows me to power up hills better than the lwb bike. It's like taking the tucked position of a DF rider and rotating it back.

Arbut that could equally be done with an RWD bike. The Lightning P38, for example, has a closed riding position and a rep for being a good climber. With most FWD bikes the comparatively low loading on the front wheel can lead to loss of traction on wet or skog(tm)-strewn surfaces.
Yes, I was going to bring up the P38, as it's riding position is similar, and it does have the rep of being a good hill climber.
And while you are probably correct about the hillclimbing capabilities of some FWD bikes in wet conditions, I have never experienced a wheelspin problem on my FWD bike. I suppose part of this may be contributed to unloading some of the weight off the drive wheel due to a shift in the center of gravity of the bike. Perhaps I have not experience this as the CG of my bike is low.
