Get the 109.5.
Zipp does track wheels with 808 rims but did not recommend using a powertap hub (large flange) with a 1080 rim due to the angles. So in their case ~88mm rim is ok. It will depend on the rim and the drilling.
I ran a road HED S9 front with a screw type skewer when we set the Nats 45+ TP record at Carson and a bunch of other races. Thought it was stiffer than the high flange box wheel I use in training.
Why anyone wouldn't run a disc rear in all events, I dunno.
I've also noticed some straight pull hubs coming out of Taiwan this year, thoughts?
Is Keirin considered a sprint or endurance race? Seems just as long if not longer than a Kilo but it seems people categorize it more as a sprint.
The time behind the motor you spend so little energy it doesn't really count as race time.
what is a good tubular tyre to use on concrete velodromes mainly for training but good enough for racing?
oh man, he had no chance!
Any WC videos popping up yet that we can watch in the states?

So, my small random question :-)
Going by Carleton's recommendation of money-spend order (below for memory refreshement), the basic aerodynamic goodies sit slightly above half way in importance, what are folks' views on the relative advantages between:
a - mass start aero-helmet, (i've got my beady eye on the Giro Air Attack Shield. Currently ride with a standard road helmet)
b - super narrow bars (the 33cm Alpina..) - my current bars are 37cm sprint bar, but my shoulders (distance between acromonions) is ~33cm.
I'm an enduro, focusing on points, scratch and team pursuit.
(in my humble opinion) spend money in this general order:
- Track season pass (ride/race as much as possible)
- Road Bike
- *basic* equipment (chainrings, cogs, tools). Notice that I didn't say fancy carbon or aero gear.
- Race entry fees (but this should be covered in the season pass)
- Skinsuit, aero helmet, booties
- Diet for Athletes book. This will change your energy and fat levels.
- Gym membership (if you plan to be a sprinter)
- Coaching (optional really)
- Travel to other tracks for regional type events to broaden your horizions
- Aero front wheel
- Fancy carbon/custom frame
- Aero disc
I'd get the bars first, for no other reason is that bars tend to be more or less forever. Start getting used to the narrower bars ASAP. IMHO, position on the bike (including bar width) is what you sort out first prior to messing with aero wheels and helmets.
Besides, the benefit of an aero helmet for mass start is tenuous at best. Not nearly as clear cut as for individual events or sprint.
i have the scatto 35s going to try those for mass start. i also ordered some deda 36s for both the road and track. i'll probably end up using the dedas since i tend to ride on the tops during a mass start.
