Conti GP5000S TR

[warthog1]

My new tyres it looks like;



He calls them "relatively cheap"
With respect to other tyres I don't expect that to be the case.
Oh well, have a few others to get through first so they may come down in price by then.

Don't over inflate them or use to wide a rim, particularly in hookless guise though.
21mm is the max internal width for a 25c tyre

Pretty bold claims, hopefully they pan out.

73PSI hookless is the maximum pressure allowed under the ETRTO standard. The hooked pressures are higher than most people would want to run, so I enjoy really see an issue there.

[warthog1]

Yeah I dunno about 73psi and a 25c on the rear. I am 76kg. Would be happy with that on the front but would run 28 on the rear at that pressure. Am running 25f and 28r in the TL at the moment with hooked rims.

The TR seem to go on easy as, but needed an air blast to seat. Normal track pump wouldn't do it.

Look good and may convince me to make the shift to tubeless.

I'd be running on hooked rims though, just don't see any reasons to go hookless yet. It scares me!

How hard is it to set up tubeless for the first time? I can imagine it's one of those things you get a bit wrong at first but becomes easier with practice (and youtube).

[warthog1]

I bought wheels from c r c that were set with tubeless tape in place already.
Just had to install tubeless valves.

It came with Hutchinson fusion5 tyres that installed easily.
However they delaminated forming blisters on the tread.
Now have GP5000TL and I am very happy with them. Some have trouble getting them on rims but they go on my wheels without any great difficulty by hand only.

Have gotten some tyres seated with track pump only but have needed to use my 240v air compressor with tank a few times. Perhaps one of those track pumps with the storage tank to provide an air blast would be the go.

I am using Hutchinson sealant and it works but I have read orange seal endurance is very good

I run 65 psi for a 25c rear Schwalbe One TL tyre on my commuter, 55 psi 28c on the front. Personally I've never had an issue, I'm around 74kg.

I've been doing it for a while now and as you say, it gets easier over time. I think a lot depends on what tyres and rims you have. My Hunt wheels combined with Schwalbe One inflated just with a track pump, I was quite surprised the first time.

My other Hunt wheels combined with Panaracer GK SK needed the tubeless inflator. I did have to use the tube trick and remove one side only with a GK SK but that was swapping it onto another wheel so it had loosened up a bit. GK's with my Farsports wheels (no spoke holes) also needed the inflator to seal. I just use a bit of dish liquid on the beads as well to help them seat.

I would definitely get some sort of inflator if you don't have an air compressor, I needed to go into a shop when I first got the GK's so I purchased an inflator the next day. Stick with Orange Seal or Squirt sealant, easy to remove from the frame if you do have a puncture.

I've setup GP5000tl a few times - whilst not the easiest tyres to fit, they weren't too bad, with the correct techniques. Overall tubeless is a bit mute difficult than clinchers but not that much more.

A few tips
1. Make sure the bead is sitting in the centre channel all the way round when trying to seat the second bead
2..Try not to use your thumbs, instead use your palms and roll the bead over the edge. You can even wear washing up gloves to help you grip the tyre and save your hands
3. Use soapy water to lubricate help the bead when trying to fit onto the rim and for easier seatting
4. Remove the valve core to allow easier initial inflation
5. Get a sealant applicator syringe to inject sealant via the valve stem.
6. An air compressor or tubeless inflator can save you a heap of time if you have issues getting the bead seated.

[Mr Purple]

Thanks. I usually struggle to fit any tyres (even clinchers) but have a Koolstop bead jack and another couple of options so should get there.

Also need a new track pump, so I'll get one of the ones with the canister for tubular inflation.

Can you get it badly wrong and find out halfway down a descent? Doesn't really look like it - it'll either hold air or it won't.

I haven't ridden hookless, but about the only way I see that happening is hookless at too much pressure.
I see them as generally less likely to suddenly deflate than a tubed tyre as you are far less likely to pinch flat.

[Mr Purple]

I'd be converting my existing Light Bicycle tubeless ready hooked rims anyway, so that isn't an issue.

I had such an issue beading clincher tyres, I'm honestly not sure it would be any harder with the right pujmp (except for potentially spraying sealant all over myself/the garage/the cat or small child).

[blizzard]

I run the GP5000s on Lightbicycle AR46 rims, which is supposed to be a hard combination to get the tyres fitted - it's difficult but definitely doable with hands and a tyre leaver.

Definitely seat the bead without sealant, deflate and check the bead has seated all around and then add sealant and reinflate.

To these excellent tips I would add:

Warm the tyres beforehand - either by leaving them in the sun for a while, or the oven VERY low (50C). Makes the rubber more flexible.

[warthog1]

Well they don't test better than the TL.

I would argue worse, given puncture resistance is reduced.
I never had trouble mounting the TLs and have hooked rims.
These replace the TL, so not really impressed tbh

[foo on patrol]

Also not so puncture resistant.

[warthog1]

Also no so puncture resistant.

Still, compared to a tubed tyre they will be superior to anything rolling within cooee of them.
My experience thus far, using Hutchinson sealant, is that it is very effective at sealing small holes like glass and wire.
Tubes are done for me. I carry one in case the sealant doesn't cope.
Hasn't happened yet.
Many just carry a plug kit according to weight weenies.

Will probably buy these tyres as I am that happy with the TLs, but I'd have been pleased if TLs continued.
Got a few in the drawer at home, enough for another 12 months.
