Road performance
The rule for making a tri bike fast applies to road bikes as well: Lowering aerodynamic drag is the best way to boost speed. The S5’s wind-cheating features outdo all but the very best tri bikes. Coupled with Enve’s SES 6.7 carbon clincher wheelset, this bike is sure to save energy during a breakaway from a group ride. And stiffness isn’t sacrificed for speed. This bike kicks hard over hills and for signpost sprints. Moderate vertical stiffness is the only tradeoff. The frame rides rougher than some, but the wide Enve rims broaden any tire and help dampen vibration. A lighter bike can certainly be had for this price, but maybe not a better one.

Tri convertibility
Wind drag isn’t a problem—this bike has performed exceptionally well against other aero road bikes. Frame geometry is also suited to triathlon fits, but the seat post creates an issue for some. Even the forward slot on the two-position post doesn’t situate the saddle far enough toward the bars for many riders, and the post’s unique shape means aftermarket seat posts that position the saddle forward aren’t compatible. A saddle such as the ISM Adamo, which can slide far forward, is a good antidote to this tri-fit quirk.
