Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Rotational weight in rear wheels

What I've noticed is:

A B43 on the same bike of mine, running the same EAI cog count and lockring, weighing (guess) about 1500 grams, is noticeably harder to skid than a 1050ish gram mavic ellipse, same tires, under the same conditions.

Less rotational weight = easier skid/ skip stop?

I just put a ellipse rear on my rig as well. And it does feel like its easier to skid. Also it seems quite a bit easier to accelerate as well. I had a high flange Phil wood with a deep v on there previously.

aside from durability, I don't see much advantage to an over-built deep vee or b43 for street riding. I put a set of open pros through a couple thousand miles of fixed street riding this summer and I found the improved acceleration to be more than worth the SLIGHTLY decreased durability.

Placebo. A Mavic ellipse rear is 1039 gms (claimed) and isn't going to be much lighter than a deep v with phil hub.

Pro wheel builder rates a philwood to deep V as 1200 grams, give or take 100 or so depending on whether you pick high flange/low flange hubs/flipflop cogs/spokes/lacing pattern.
