Alongside its new Emonda, Trek launched three new wheelset ranges, with a total of four new pairs of wheels; the Aeolus Elite TLR, which came in 35 and 50mm depths, the Aeolus Pro 37 TLR, and the flagship Aeolus RSL 37 which we have here. These wheels came slotted into the dropouts of the brand new Trek Emonda we received back in June, and given these were just as newsworthy as the bike itself, we couldn’t resist slotting them into a few different bikes to see how they stacked up. 

But if you do opt for the Bontragers, what you get is an energetic set of race wheels that pairs well with 25 and 28mm tyres that are well behaved in crosswinds.

While it's hard to assess durability in a relatively short test period, the Aeolus were still true as the day I received them when they were sent back. Better still, if you do write-off a wheel in the first two years, Bontrager will replace them and also backs them with a lifetime warranty.
