Gravel tyres

[warthog1]

Well I have found my gravel king sk front and ss rear a good combo for the riding I do. Apart from that butt ugly brown tyre I got they have been very reliable.
Interested to see how this tests and it reads like they have made them a bit easier to seat.

Looks good. Have used my vote to get it tested at BRR

[Bethanyc]

I have been running a set of standard X1's in 40mm for a few weeks now, very impressed with them.
Can confirm that were easy to mount. I was able to mount the bead with hand pump, and got them on my Fulcrum carbon rims with just my thumbs.
They are very fast on tar to me feel about as fast as my gp5000 AS 32's , having said that I have beaten heaps of my segments with them, so times would say faster..even at 30 psi.
Have put now 75ks of gravel as well also great grip and seem very puncture resistant.
Wear also has been great. So not like terraspeed in that respect.

wonder if anyone has had to top up their tubeless sealant mid-ride (because of a puncture that wouldn't seal) and if they did, what did they use?

(looking for a solution that allows me to carry <100ml sealant. still need a nozzle or tip to pour sealant without wastage)

[antigee]

Pretty sure must be adaptable small no cost bottles out there...think I've seen the take away soy sauce pouches suggested but if they work must be bigger than the ones I've seen

.. Stan's do a 2oz 59ml bottle intended for emergency repair

on Pushy's but I noticed LaTour who are local to me and I use more and more have cheaper if buy 4, other retailers are available

one more thing to have gone off in the tool bag when needed!

[warthog1]

I carry plugs. I also put plenty of sealant in my 40c gravel tyres (~90ml).
If that doesn't work I'm bunging a tube in.

You can find small, clear, flat, flip-top plastic bottles out there. Various sizes.

Can either carefully hold the square tip up against a valve [core removed], or round the square until it just fits inside the valve inner-diameter; squeeze in sealant.

I generally carry one or two small 50ml? bottles, jammed [sitting upright] at the rear of a small top tube bag.

Pretty much every sealant brand makes a small bottle for exactly this purpose.

Orange Seal 118mL

Stans 59mL:

As a bonus you only ever need to buy one so you can refill it from the big bottle.

thanks. lots of useful info there.
I'm currently using Orange sealant so I'm stuck with the Orange options (the smallest Orange bottle is 2x the size of the Stans but 4x the price .. lol).
An alternative option, like someone suggested, is to look at generic travel bottles.
The challenge is to fit an injector or nozzle. The sealant is quite fluid - if/when trying to pour into the valve (with core removed), I can easily imagine it spilling out all over the tyre in the heat of the moment. I think this is my best bet.

[Mr Purple]

I've used that exact one - it worked quite well.

[warthog1]

I am confused why you would consider the need for carrying extra sealant. If a tyre holes, roll the hole to the bottom and let the sealant do its work. If that fails roll the hole to the top and plug it. Roll it back to the bottom to let the sealant work. If you run out of sealant the hole is too big or you haven't checked the quantity for too long. Pop the bead run your hand around the hole to make sure what caused the hole isn't there, bung a tube in and carry on.

[Mr Purple]

Good point. I've never taken a small bottle on a ride, but do take one when I take the bike on holidays.

If the puncture isn't sealing, extra sealant isn't really ever going to fix it anyway.

sorry, just saw that you had asked me this question.
i just want to be prepared for all eventualities as I some times ride gravel by myself.

- i've had sealant unable to seal, in the middle of the bush. rotated tyre with puncture at bottom, didn't work.
- multiple replacement tubes pinched flat on the same ride (was shocked at how little sealant was left in the tyre)

just relooking at all options.

for instance - my current plug solution requires the use of rubber cement. potentially not ideal in cold/damp weather. so that's another item to research.
also testing different sealants.

so essentially for my OWN peace of mind, i'll bring ..
- tubeless setup
- plug
- sealant
- tubes x2
- adhesive patch kit x1
- vulcanized rubber patch kit x1

fingers crossed

[warthog1]

Fair enough. I gravel by myself too. 50+ km away from home at times. More than 15k km of it on tubeless tyres. Multiple punctures, mostly sealed by themselves. Plugs required a handful of times and tube twice. Heavy thornproof tube has done the job on those occasions. I've got 2 tubes in the saddlebag. One is a long stemmed road tube for when I use my 50mm road wheels. It would work at low pressure in the gravel tyres at a pinch I guess. Haven't had to use it yet.

Carrying the patches too is a good idea. It sounds like you may be a long way from home at times.

[warthog1]

Somebody I rode with today put me on to this with respect to gravel tyres;



Interesting
It just so happens those wheels, or a slightly cheaper version with round, rather than eliptical spokes, came with the Reacto. Same rim profile at 60mm deep.
A 53mm race king will fit on the front of the Revolt. Not the rear though, I don't think. A 45 will, or maybe even a 50.
May try it out at some point.

[warthog1]

Well I got onto some 29×2.0 Conti race kings. Got the text they are onboard for delivery.
The front will be no problem but the rear is going to be tight. I avoid wet coditions like the plague fhough. We shall see.
I have embraced big tyres on the road and am not going back now that I have the frame that can handle them.
May as well see how they go on the dirt too.

[warthog1]

Got em on there;



The front no probs but the rear touches on the drive side. At least the moulding nipples do. It' ll rapidly have no paint if I ride it like that. Down to the Giant store for a 45mm Schwalbe. That'll do.

I'd have just got out the angle grinder and knocked the edge off the tyre on the offending side

I did think about it The side wall is also very close to the chain stay on the drive side. Giant says max tyre size on the '21 revolt is 45c. Fitted these measure 50.5mm. Would go on the '22 and later Revolt.
Had a ride today. Better over the loose, rough stuff and over sand. No better on hard pack but not notably slower either. Happy with the upgrade.

[warthog1]

Those wider tyres are not coming off anytime soon. Not faster on the smooth stuff but they are on the rougher stuff, particularly rocky descents. Better shock absorbtion, better control, better comfort. Will try a 50mm Schwalbe on the back next time. ~6mm clearance on the drive side, so if it is only 5mm wider than the 45 (2.5mm each side) it should go. That Conti 2.0×29 on the front is great. Running 25psi f & 31 r.

[Mr Purple]

Interestingly I have a few events coming up and I'm undecided on whether to mix up the tyres or not.

Currently running 42mm Pathfinder SWorks which I'm very happy with. RR about 24W, run them at 35 PSI front and rear.

Have three events:
- BVRT 150km; definitely Pathfinder territory. Wide, open, reasonably flat and reasonably high risk of punctures. I know they're fast and bulletproof out there.
- Brisbane Roubaix: interesting one, 100km event with 1300m elevation but only 10km of gravel. However some of that involves creeks. In theory could go with a wide slick but given the GP5000 TR 32mm still has 16W of RR it hardly seems worth it for a total of 16W.
- Sunday Creek Classic: 120km/3000m and apparently the second half is absolute hell for converted roadies like myself. Sketchy descents, rocky, loose, the works. Half thinking Pirelli Cinturato H in 45mm if I go ahead with this madness.

Any thoughts?

[warthog1]

Cinturato H aren't anything special for grip. I found them a bit fragile too.
I can't compare them to your pathfinders though as I haven't used them.

[Mr Purple]

Any tips on a nice wide tyre for loose, dry, rocky gravel?

I suspect the answer is ‘take a mountain bike’ but I don’t have one!

Pirelli Gravel M. Still roll well, but good tread pattern.

Just sold the pair off mine for $50 !!!

Therecis a national level female gravel racer here. She has used Schwalbe g one r on the front https://ccache.cc/products/schwalbe-g-o ... super-race
and g one rs on the rear

This video is worth a look



Depends on your tyre clearance. I have a 2.0 conti race king on the front but it wouldn't fit on the rear.
