MAvic reflex - is it for strong 75kg rider?

Easton EA70 comes in a tubular variety.....also, you can get some older Ksyriums in tubular. Kinlin comes in tubular also....

Interesting question.

I got myself a set of Mavic Reflex with DT Aerolites (32) on DT 240 hubs a few years ago. The initial idea was to get them as racing wheels as they are supposedly quite rigid, fairly light, not too expensive to replace in case of a crash and the tubs should give some extra safety in case of a puncture.

While I like the ride quality, the wheel is not really stiff and descending in a race situation north of 75km/h does feel quite sketchy. In fact I gave up using them and continued using my training wheels (Fulcrum 3) instead. For my weight ( 77 - 80kg) they feel much better particularly when descending.

So I still like the idea of an aluminum tubular rim but I would not get the above combination again.

How much of that might be attributable to the DT Aerolites? Do you notice a difference in high speed sketchiness depending on the wind conditions (e.g., gusty cross-winds)?

@ Hammer

Good question. It's difficult to say as I have no real comparison with similar setups but different spokes. I just find the steering quite a bit wobbly although cross winds seem to have little effect. In general I think the set-up is just a bit too light and flexy for my weight and height (1,88m). However what I really like is the perceived (major discussions on that have been led elsewhere) smoothness of the tubulars.

Hmmm... can't say for sure, but I think it's the Aerolite spokes. They are very thin in the middle, but if the wheels are sketchy with 32 spokes, you have to wonder. I don't think it's the rim choice, Reflex's are a good tubular rim. I have several wheels built up with Aerolites and am not sure I'd use them again. I'm pushing 90kg. I have some Ambrosio Nemesis 32 hole rims I'm about to build up onto Campagnolo Record hubs. I'll be using good old DT Swiss Comps. Not the ligthest of wheels by any means, but classic and hopefully, bombproof.

Thanks for info. I am intrested for mavic reflex becouse they are very light and looks cool. For up/down intense race low cost wheelset.
Spokes are very long becouse rim is low profile. Are dt competition more "stable" than aerolite?

I just picked up a pair of kinlin tb25 rims as another lightweight alternative. They're definitely a little heavier, but seem like they'll build into a stiff and relatively light wheel set.

I'm not sure if they're more "stable" but my intuition would say yes simply because there is more material. Aerolites are essentially flattened DT Revolutions, which are a lighter version of the DT comps. The thinner spokes tension up higher but not sure that translates into much. Maybe @Ergott can help more. He seems to be one of the more experienced wheelbuilders on this site.

What about Ambrosio Crono F20's? They have gotten heavier over time, but are still one of the lighter aluminium tubular rims...

HED makes a wide/light aluminum tubular rim. It's welded and has a good reputation for durability. They are more $$$, but liekly worth it over the kinlins. Likely the same price as the F20s.

Velocity also make a few light tubular rims.

I would get the HEDs.

Too bad American Classic didn't continue their magnesium tubular rim. That would have been a sweet rim if they ever sold it aftermarket.

+2 on the ambrosio chrono F20, I just built up a set in 28/32 and they're awesome. CX-Rays, bikehubstore hubs, and brass nipples. Just hit 1,400g.
