Continental GP5000 TT TR

[OtterSpace]

Currently trying trying to figure out which GP 5000 TTs I should get for my Roval CLX 50s (ID 20.9mm outer 29.4ish).
With the outer diameter in mind, would you get the 25s or 28s?
I've been previously running 25mm GP5ks with latex inner tubes.

I'd avoid all 25mm and smaller tires for a 29.4mm wide rim which rules out the 25 tt.

28f/28r tt or 26f Aero 111/28r tt

I'd likely go 28f&r tt and see how you get on with them and see true WAM first as the Aero 111 rolls slower, is new so user data is limited, only helps in higher yaw angles, and is much more expensive.

In this case, I don't see any reasons why 25mm tyres should be avoided.
Rim internal width is almost 21mm which is normal. Pro teams running 26mm TC tyres on roval rapide wheels, which are 21mm internal and 35mm (front) external width.

TC 26 in Rapides measure between 28mm and 28.5mm, which is not that different to what GP5000 28 measure in same wheels (less than 1mm difference). I would not use the TCs in 26 as comparison to GP5000 25.

TC 26mm on 21mm IW are mesures 28mm.
Not sure about this year TdF, but last year Ineos was using gp5000 25mm on front wheels C50 which are 21mm.
I haven't seen anyone complaining about issues with gp5000 25mm on wheels with 21mm internal width. Especialy when most of these wheels are with hooked rims.

I wanted to chime in as well.
End of last year and early in the season I've ridden Conti GP 5000 S TR tubeless in 28mm for about 5 months (clinchers before that)
then switched to the 28mm TT recently.

I'm at 1867 miles with the TTs and I'm extremely happy with the performance and puncture rate. My rate of flats is same or even better (roads are a bit more free of debris in summer after all) than my S TR's have been. So far I have only gotten 1 rear puncture and it sealed with no problem. I'm using 40mL of silca sealant in each tire.

I'm beating my descend PR's on roads I've been riding for the last 10 years as well which is a good sign (though some of that could be attributed to the bike).

I don't know if I'll be able to push them much past 2000 miles however. Rear is very close to the limit. Interestingly they wore rounder than the GP5000 S TR. Might be other reasons for it or due to thinner side walls? Not sure. I usually see a flat spot on the rear when my tires are old. This one's still very round but the thickness/wear indicating dots or whatever are almost gone.

2k miles is not a lot obviously. It means I need almost 4 sets (or at least rear) per season. But it might be well worth it for how good these tires are.

I will definitely try AERO 111 in the front next to see if it's worth the marketing hype lol. But TT's might be my staple at the rear. If it gets annoyingly flat prone in the winter I might do GP5K 30mm then AERO 111 / TT for PR attempts and races.

Passed 2,344miles (3,772 km) today - still very happy with the tires. No flats - one rear puncture that sealed without me noticing until I was done with the ride and noticed sealant on the bike. Front has a ton of life left, but the rear is near end of life. Earlier I thought I might get 2,500 miles (4,000km) out of them, but I might get a few more before the rear wear marks disapear. I'll report back when I swap them out.

When I look at the stats from BRR, the big difference that jumps out to me is the tread thickness between the TT and TR. That would also help explain why the TT isn't as squared off when it's worn down, as there isn't as much material to square with.

That's also the reason I've opted to run the TT as a front-only tire. I like having the added tread and wear available on the rear tire - I can effectively get a full season out of it, where I'd need at least two TT tires to get through the same distance. Really it's just a cost savings exercise. And since I don't have any important races in the first half of the outdoor season, it's like getting that tire wear for free vs running a TT.

After three seasons on the TRs and now one with the TT on front, I can't think it's possible to have had better performance. Grip, speed and puncture protection have all been excellent, with a consistent wear rate that makes these tires a (relatively) great value.

You might be the first person ever to say the TT has good grip! It's the main weakness. If they add the compound from the AS TR or 111, then it would be a solid 10/10.

Honestly, no need. Aero 111 front and TT rear would just make the best performance IMO. TT grip is plenty for rear. Front, I'll never say no to more grip so 111 data suggests it's the best ever.

I think my setup will be

Summer Front: 29mm Aero 111
Summer Rear: 28mm TT

Winter Front: 29mm Aero 111
Winter Rear: 30mm GP5000 S TR

My position is so far forward that I have more weight over my front axle vs rear axle. With GP5K S TR or TT TR I routinely skip my rear tire while accelerating out of corners on bad pavement in dry conditions. I have to consciously scoot back in the saddle. This is not the case with the ENVE SES Race Days or Pirelli P Zero Race RS.

I see no reason not to run Aero 111 front and rear even if I’m not getting any of the high yaw stability benefits in the rear.

if the Enve RD's continue to hold up I will be year round

Why not just go 111 front and rear?

I have doubts the A111 will be in the same caliber as the RD's in feel. Conti's have always been meh in that dept for me.

I doubt Aero 111's extra grip can overcome weight distribution issues while pedaling hard but
For me, I need grip in front and best RR possible in rear. If it was a motorcycle I'd say it's a different story

If by RD you mean Racedays, that one's a non-starter for me as I can't get them on the rim and I've literally tried everything.
Also 111 tested higher grip than RD's. I'll ofcourse leave it to individuals for deciding if BRR's grip tests are accurate / reflective of real world or not.
