At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.
Good scores are more common than bad, because fortunately good products are more common than bad.
Bontrager's road 'R' tyres come in a range of four options - top of the tree being the R4 with these R3s a notch below.
Out on the road the low weight of 185g per tyre makes them easy to whip up to speed while the 120tpi casing has enough suppleness to iron out small road imperfections, even pumped up to their 125psi maximum.
Grip is very good thanks to a soft rubber compound and on a dry day you can really bank the bike over and be confident it's not going to slide out from underneath you. The R3s give a lot of feedback to your hands so when they do start to break traction you can easily feel it coming and adjust your speed and position to counter it.
On the flat, rolling resistance is low and speed easily maintained, how much of this is down to the 'Slick Aero Wing Technology' is anyone's guess though. This is the name given to Bontrager's design of sidewall profile which fills the gap between tyre and braking surface once the bead is hooked into the clincher rim. It doesn't work with every rim though; ironically my deep section aero wheels still had a gap but the Campag Zondas I also tried them on fitted absolutely flush.
Like the Ultremo ZXs these replaced, the R3s are performance tyres and won't last long if you use them every day or in bad weather. I did get some wet miles in though and while the puncture protection belt kept things inflated, small stones and flints did leave marks in the rubber.
If you do happen to flat the R3s are very easy to remove and refit just using your hands so you shouldn't be left at the side of the road cursing your bloodied knuckles and snapped tyre lever.
Seven colour options in the 700Cx23mm size should enable you to colour match your bike, but the 700Cx25mm and 650Cx23mm sizes come in black only.
All in all the Bontrager R3s are impressive race tyres virtually matching the Ultremo ZX's for performance and grip. Taking into account that at £29.99, the RRP of the R3s is 12 quid cheaper per tyre than the Ultremos, they are a performance bargain.
Fast, grippy and relatively cheap - but keep them for the Sunday best bike.

Tell us some more about the technical aspects of the product?
Puncture protection belt
120 threads per inch carcass
Aero side walls
Fast rolling and grippy.
Don't expect to get mega mileage out of them but keep them dry and they should see you through a race season.
A quoted 185g is pretty good in terms of the competition.
Even at max pressure they aren't bone shakers.
£30 places them in Conti GP4000 territory, and I rate the performance of the Bontragers much higher.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for road.cc back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
