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.
