What tyres for…. tubeless CX

I’ve been running a set of Kenda Small Block 8s on my cx, tubeless using sealant and stand rim strips. After some initial faffage where they leaked air slowly through rides, they settled down enough to work brilliantly – no punctures, and.most.importantly no pinch flats which I’d found a real problem. Unfortunately recently they seem to have started leaking again. the leaks are from very small pinprick holes that I thought had all sealed but they keep opening then sealing again but obviously means losing pressure over time.

So, what tyres have you used with a similar setup that work well? having had zero problems with similar tubeless setups on my mtbs there’s no way I’d go back to tubes but I think that sb8s clearly aren’t suited to the task.

Using SB8s & Larsen MiMos at the moment. Have had success with Mich Mud2s as well.

Bump!

I’ve had great success with all-flavours of Maxxis run tubeless. They take a while to seal completely on Ksyriums, but once on there they’re perfect.

Has all your sealant dried up? Might be worth putting some more in there.

Normal mtb SB8’s are fine tubeless. I’ve tried Kenda’s, Maxxis, Schwalbe, Panaracer, and all have been fine tubeless with sealant.

No, sealant’s still sloshing around in there – you can see it seal the holes as they appear too.

If it’s been in there a while might still be worth replacing the sealant. Does seem to get less effective after a while. Guess the higher pressures with CX tyres would make it lose a bit more air before it seals too.

I had a similar issue with a normal SM8, sealed fine initially (could see the sealant had done it’s job on plenty of pin-prick sized holes in the sidewalls) but every time the tyre got wet it would leak and take a while to reseal, odd as I’ve not had any other tubeless tyre suffer from getting wet.

Hi,
Sorry to but in on thread but having trouble sealing my cyclocross rims up tubeless.They are Mavic Open Pro with schwalbe CX Pro.Used the spoke tape with a Stans rim strip and air is escaping everywhere.Tyres seem a baggy fit though! Any tips?
Thanx Max

I noticed exactly the same actually. Again, never had it on any other tyres.

Turner fan – reckon you need to build up the rim bed with more layers of the tape so that the tyres are less baggy.

I love tubeless on my mountain bike but have had no luck on the cross bike. It seems to me that if you want better traction and speed, like you get with tubeless, you have to get into glue sniffing and saving for a year to get a new set of tyres. I would be very happy to learn if this isn’t the case…

Most tyre combos work a treat on a stans 340 rim…

Vittoria and Schwarble been the best…

Ride quality still nowhere near as good as a tubular.

Kenda innit? Thin sidewalls. They’re always going to be porous. Try something other than Kendas. All the early ‘which tyre can I ghetto?’ advice said avoid teh Kenda.

traildog – when the sb8s held air they were fantastic tubeless. if as people say, it’s just a Kenda problem then I’ll be very happy.

Aren’t Kendas meant to be rubbish for tubeless conversions.

BTW Clubber, I’ve emailed you about the Epicon you’ve got for sale

not tried tubeless on cx wheels yet but planning to try it soon.
i have mich mud 2 and they are supposed to work fine tubeless from my searches but rim compatability seems to be the biggest concern, e.g too baggy on open pro’s so much building up of the rim would be needed.

clubber what rims you using tubeless? and anyone else?

I’m using Campag Proton rims. Also had success with Bonty Racelites & Open Pros.

The lower pressures I seem to be getting away with are making a big difference – 40psi ish in the south downs.

Go stans 340 for cross tubeless. Works fine with most rubber. A very quick mate used them to top3 in last years London league.

Still say in ride quality nowt beats tubs! Sorry

Tried tubeless but at the pressures I’d want to run they burped badly.Saved the pennies and went with tubs this season (should have saved harder and bought dugast’s though 😕 )

Halo Aerorage rims with stans rim strips for me. they go up a treat. it’s the staying inflated more than a few hours that’s a problem with the kendas.

Mine never burp but I run 50-70psi

Steve, mailed you back.

thinking of getting some velocity a23 rims on miche primato hubs, reasonable price weight hopefully durability and wide rims, hope they work tubeless
