I'm about to 'pull the trigger' on one of these. I'm not asking which one is better, but is the cost of the SL justified? Hub weight means nothing in a wheel, and I think they have the same internals, right? My Fulcrums are in the beginning stages of crapping out, and they're too heavy, to the point where I think I'm being held back some by them. They're even beginning to flex during sprints and climbs and I can feel it rubbing the rear brake under torque.

Here is the comparison chart. https://www.saris.com/comparison/powertapcomparison.htm

The weight is the primary difference.

I recently got the SL, and picking up the bike with the PT wheelset (Bonty Race X Lite Aeros) versus my old wheelset (Mike Garcia POS Niobium 30's), it is noticeable. Hasn't really slowed me down at all, but an extra half pound with the Pro over whatever I added with the SL would kinda suck more.

Plus the carbon looks cooler. That's a huge bonus.

The new pros look exactly the same as the SLs.

If you're considering an older Pro (yellow plastic cap) vs. the SL, I think the plus would be in the SL's water resistance. It's supposed to be more weatherproof. I don't have an SL, but I have two older Pros, and they will quit working in any sort of rain or heavy spray from the road. They dry out and start working again, but it's still a pain in the ass.

The only difference between the new generation Pro and the SL is the axle and and the bearings. The seals are the same, and they look practically identical. It really just depends on how much the weight difference vs. cost matters to you.

Or... you could be like Floyd and get a custom built PT SL with a hand built carbon axle (dropped 100 grams). Lace it to a Zipp 202 and you're good to go.

Ah well....just get an SRM.

the ligther SL has an aluminum freehub body which will wear out in a matter of months, requiring replacement and extra $$.

I ended up buying the steel freehub body instead of the AL one, essentially paying to downgrade. I wish I would have bought the PT PRO instead of the SL in the first place.

If my SRM deal doesn't come to fruition, I'm getting a Pro. What do I care if my bike goes from 19 lbs to 19.5 lbs? I'll still carry all six cans of whoopass.

The cassette free body is also steel on the Pro vs aluminum on the SL. If you're using the wheel for training, the Pro is a much better choice.

Okay, THERE WE GO! I hate aluminum freehubs, so this is a great plus for the Pro. You're all saying that the new Pro is more weather resistant, too, and with carbon or no?

Not sure whether it's more weather resistant, since I've never disassembled my Pro and mine only came with SL manual. It does look like the SL though; as well as coded hrm belt and the newer computer with more memory (same as the SL; not the old Pro).
