Jackson McNealwrote a review of Reynolds TR 309 Boost Wheelset - 29in on September 25, 2019
Familiarity: I've put it through the wringer
Alright, just to get this out of the way - I haven't always known much about Reynolds, let alone gave them much of a chance, compared to most of the traditional higher end wheelsets out there. On my radar was always ENVE, Industry Nine, Crank Brothers, etc. You know, the works. I didn't pay too much attention to Reynolds. Not sure why that is, probably for no specific reason, but there just isn't as much hype around them as there is around other brands. I think that should totally change. Reynolds hands down blows their price point competitors out of the water, while holding their own against the "best" wheels out on the market today.
After riding these wheels for over 100 miles on rough singletrack, I have found that these wheels are stiff and plenty wide. The build on them is fantastic. I found myself trusting these much more than my previous carbon wheel set (which blew up on me). They were stiffer for sure, but it didn't seem like they were overly stiff to the point that they were rough and uncomfortable to ride on. From riding other carbon wheelsets, I have found that that is a hard balance to find. Stiff enough to track well and be responsive, but also compliant enough to not feel extremely rough and overly responsive. These wheels do just that and I was thoroughly impressed.
When seeing a wheelset in this price range, I usually expect heavier carbon layups. For what they are (a trail wheelset at about 30mm inner rim width), along with the price range, weighing in at around 1700 grams isn't too shabby. Even better, the wheels have a lifetime warranty on them, meaning if you do manage to break a rim, then Reynolds will replace it for no extra cost. However, you would be hard pressed to actually break it. Coming off of that previous pair of carbon rims, I felt more confident and capable with these wheels compared to the others.
Overall, if you are in the market for a wheelset, you should seriously consider anything made by Reynolds. Their price point can't be beat, while matching the quality, weight, and performance of higher end wheelsets. Plus a Lifetime Warranty!? I'm totally sold on them.
