Last year I got a Trek Fuel Ex 2017 that came with a set of SUNringlé Düroc 40 wheels, I have since done approximately 1300 Kilometers or 800 Miles on my Fuel Ex and thought it is high time to write a little review for all those interested in this fine set of Wheels.

Düroc 40 Specs
The Düroc 40 is a Plus size wheel that can take plus tyres up to 3.0 Inches. Although the recommended max size is 2.8 I have been running Bontragers Chupacabras and WTB’s at 3.0 Inches for almost a year with no issues whatsoever. Here are some of the main spec’s of the Düroc 40
- Outer Rim Width: 40mm
- Inner Bead Width: 36mm

- Hub Spacing Rear: 148×12 (also: 135xQR, 142×12)

Build Quality & Durability
SUNringlé is well known for their amazing build quality compared to product cost. During the last 1300 Kilometers my Duroc 40’s have taken a lot of abuse in many different kind of terrains with nothing more than a few little scratches. My previous wheelset had suffered a dent within the 1st month of riding it while the Duroc’s are 100% in tact after 1300 Km. Quality Score 10/10
Wheel Weight
The Düroc 40 set weighs apx 1.93 Kilos or 4.25 Pounds. Given the strength and cost of this Wheel set the weight is quite amazing. Compared to similar wheels such as the Nukeproof Horizon and Stans No Tube, both price and weight are better on the Düroc 40. Unless you are willing to spend a lot more cash and sacrifice wheel strength this is as good as it gets. Weight Score 8/10
Price
At the time of purchase (Aug 2017) the complete wheelset cost apx 510.00 Euros (570USD / 435 GBP) which was in line with other plus tire wheels such as Hope Tech and Stan’s No Tube. The price vs durability and weight of the Düroc 40 make that price well wroth the investment. Price Score 7/10.
The Verdict
The Düroc wheel family is durable and wont cost you an arm and a leg making it a perfect candidate for even the most demanding trails and terrain. The total weight of just under 2 Kilos is well acceptable and will allow you to pedal up technical ascends. After riding the Düroc 40 for close to 1300 Kilometres (and hopefully many more to come).
