Does anybody have any experience with the new Bontrager R3 tires? https://www.trekbikes.com/us/en_US/equi ... Code=black

It's the new version, looks to be very light, claimed grippier, etc etc. However, I can't find any rolling resistance data or any review of the new ones.. Does anybody have any experience they wouldn't mind sharing?

I have a few hundred miles on a pair of 25c R3s. They weighted in at 211g and 219g. Mounted on my checkpoint on some farsports 35x28 wide wheels. So far so good. I don't ride clinchers often, but these tires with standard tubes actually ride pretty nice. Decent weight and great cornering grip. Wish I had a more scientific report for you. They seem to roll better then the gp4000s they replaced. The ride is also much smoother with the R3s, that was noticable. The casing on the r3 is a little more supple. Not supple like a veloflex clincher but also not as fragile.

Have not tried these yet, but if they're an improvement upon the 2017 R3's (which I have on my bikes -- 25mm @ 205g/each on one and 28mm at 244g/each on another), then they're nothing short of amazing. Lightweight, great grip on cornering, excellent puncture protection (I don't remember the last time I changed a flat), and a smooth yet efficient ride. The 28mm tires are cushy and are noticeably faster than the 25mm tires on mixed terrain. I will upgrade to the 2019 version once one of these sets are ready for replacement.

The Bontrager site says NEW Bontrager R3 Hard-Case Lite Road Tire Model 27590 and lists the 25C @ 200g.

The tan sidewwall Bontrager R4 320 Handmade Clincher (25C @ 230g) also caught my eye.

I wonder who makes these for Bontrager?

Vittoria makes the tubulars and R4 320. The R4 320 clinchers are puncture prone. Similar to a veloflex Corsa/master in ride quality. The tubulars are great, been running them exclusively for 4 years or so. Only flats I get are if they are major punctures that would even kill a clincher.

In that case I will stay away from the R4 320 clinchers but the new R3 Hard-Case Lite 25C @ 200g is presumably a different construction and likely from another factory.

I recently swapped from Corsa Gs to the R4 tubular (25) and have put about 1,000km on them so far. Very grippy, better in the wet than my Veloflex Arenbergs and haven't had any issues with punctures yet. They feel a more plush than the Corsa Gs, maybe a tad slower though, but definitely faster than the Arenbergs. Overall very happy with them so far and prefer them to both the Corsa Gs and the Arenbergs in terms of ride quality and comfort.

My next set of tires will probably be the Veloflex Service Corsa.
