Weight Weenies

I guess disc wheels aren't really WW material but I really can't find any find any reviews on the 3T Mercurio disc wheel. Has anyone here any experience with this wheel or any wheel from 3T?

I have their new Mercurio 80 tubular wheels. Just glued tyres on them and will ride this weekend.

The disc apparently is designed for 'flat, straight courses'. Meaning it's heavy and not particularly aerodynamic. I expect the next version will be better!

what disc isn't designed for flat courses?

A lightweight disc!


3T says this about their disc:
"This is the specialist's wheel for short-distance time trials in still air conditions, on known-good courses."

So, to me is sounds heavy and a little un-aero. Whereas a Hed or Zipp Sub-9 will help you in variable wind conditions, etc. And a Lightweight disc helps on hilly courses. (The last bit is a guess).

Sounds like some of you guys are slaves to marketing...

Use your head

totally agree. marketeers.

as an engineer, a disc is a disc. lenticular, flat, whatever you call it. discs all have the same general advantages- they are great for flat courses where you need to TT and the aero advanatege helps, and the same general disadvantages- act as sails in crosswinds, dogs to accelerate so arent so good in the climbs. . any advantage a disc claims to have over another is going to be minuscule.

the only sub category I'd split discs into are solid discs- like the reynolds element, zipp 900s and sub 9, campy ghibli, etc. and wheel cover discs- like the FLO disc and the HED disc. there are pros/cons to each one, but relatively minor.

if you're going for an uphill time trial, I wouldnt even be choosing a disc, even a lightweight disc. I'd go for 50mms or 80mms.
( note. when i say uphill I MEAN uphill- not courses with one speedbump and the rest falts- I'd still choose a disc if the proportion of flat to hilly was reasonably favourable.)
