BRR members: Which tire is getting your vote next month?

[Yoln]

Thought it would be a good idea to have a thread here to flag interested tires to be considered for voting.

For me:
- October vote went to Road Panaracer Agilest Fast 28mm
- November: Probably Gravel ENVE Hex 40mm

[BigBoyND]

October: agilest fast

November: P Zero RS Retro

Because conti has huge (20%) penalty for tan walls and I'd like to known if it's the case also for the RS.

But I'd also like to see the fast tires from less mainstrean brands tested, like ERE, Vredstein, and Maxxis

Agilest Fast in October, leaning towards TUFO Comtura Aero 28 for November, but secretly hope Hutchinson would release a RR-optimised version of the Blackbird with outlandish performance claims and scoop up enough votes to make the winners list.

Hope they test the Bontrager Aeolus RSL TLR tyre with cotton construction.

I'm most interested in the 60mm Schwalbe G One Speed Pro which according to Schwalbe is the fastest tire they have ever made, but that is just marketing until proven. Schwalbe doesnt have the fastest rolling road tires but that is still quite the claim. Would be interesting to see how it compares to their old big one which tops the MTB tires currently and Schwalbe also has a road tire tested to around 8 watts currently.

It would be insane to see a 60mm tire test to 8 watts.

This one totally went under my radar, good catch, always interested in a new cotton race tyre!

That wouldn't be a surprise, 60mm is huge and not apples to apples to any other road tyre. We know that the 32mm GP5k is the fastest GP5k by a decent margin at 80psi. If they made a 60mm GP5k it would have ridiculous rolling resistance, but you'd be trading off other dimensions of course...

To compare two tires with vastly different widths, the air pressures need to be normalized such that the casing tensions are identical. BRR has done a test where it demonstrated that once adjusted for casing tension, a wide tire has exactly the same RR as a narrower tire. https://www.bicyclerollingresistance.co ... comparison

[Yoln]

Yeah, that's where my info came from, and what I meant: easy for Schwalbe to claim that a 60mm tire is their fastest tire yet if they don't provide any pressure data, but once adjusted for pressure/casing tension it is likely not better RR than smaller tires

[MartinHnik]

I really hope for Tufo Comtura Aero. Tufo is manufacturer of Enve Race Day, so I just hope it will be very close/the same but for better price.

Comtura aero is an old tire back from the days tufo where still crap. So don't expect nothing impressive, it's just another cheap tire.

I don't see anything really interesting this month for voting. Will just vote for Michelin power cup clinchers 28c so they can measure the thread and show people that there are still fast and LIGHT clincher tires out there. Tired of this heavy tubeless nonsense

[BigBoyND]

The Tufo website says it is part of the modern Comtura range, so maybe it's fast. But since it's a tubed tire, I don't care for it. Surprised to see so many votes.

I'm most interested in the Retro RS to see of there's a 20% penalty for tan color like with GP5k.

Otherwise:
- Power Cup TLR 30mm for size and black-wall RR. If the tan one they tested actually has a 20% penalty, then the black one would be TT-level fast.
- Enve SES Road 35mm. Enve lists the three biggest sizes as almost the same weight. Could it be that the 35mm is much thinner and faster, like a Prima?

- Power Cup TLR 30mm for size and black-wall RR. If the tan one they tested actually has a 20% penalty, then the black one would be TT-level fast.

BRR have tested both the 25mm and the 28mm Power Cup TLRs. What makes you think the 30mm would be suddenly that much faster? Even though I see (from the pics) that both the Power Cups tested indeed were tanwall , the Power Cup clincher they tested was black, and had comparable RR to the TLR versions (if accounting for the butyl effect)

P.S. FWIW, I ride the 30mm myself, and for some currently unexplained reasons have been really fast on them this autumn on my usual routes - good road quality even for 25mm TT stuff, so we could probably disregard the "wider tyres = faster" argument here.

[CampagYOLO]

Schwalbe Rick XC for me. Could be the goldilocks big gravel tyre for me if it's nearly as fast as a Thunder Burt but has more versatile tread.

Not sure we can draw any conclusions from a tubed Power Cup which could use a completely different construction.

Black may or may not be faster, but there are several reasons there's a decent chance:
-S TR in tan walls is 15-20% slower than black
- JV mentioned in a Goodyear thread that you can expect 15% slower rolling with most tan wall constructions
- Schwalbe MTB tires are also slower in tan wall by roughly that amount.
