eddy Posted February 7, 2015 Posted February 7, 2015 I am lending a 29er to someone for the Argus and will be fitting slicks. Would I be able to run 28c GP 4000 on Crest rims tubeless with enough sealant or will the bead not seat properly?

TALUS Posted February 8, 2015 Posted February 8, 2015 At what pressure are you planning on running the Contis at?I think this is the crux. Road tubeless is designed around 6 to 8 bar. That needs special tyre lips and rim design to interlock. High pressure and high speed around corners could carry risk. I think seating/ sealing is only the first part. Knowing it is safe is the second.

Rather be safe and use the Schwalbe ONE Tubeless tyre - same price as a GP4000SII... http://www.evobikes.co.za/tyres/road-tyres/schwalbe-ultremo-zx-tubeless.html
MarcL Posted February 8, 2015 Posted February 8, 2015 As all the local Cape Towners tell me... It's the Cape Cycle Tour. The Argus is so last season Seriously I run tubeless road tyres on my road bike and the need special tubeless rims. I'm not sure the Creast will have the rim structure to run high pressure tubeless tyres.Mind you, if you can run MTB slicks with tubes at high pressure , maybe the rim structure is fine. If you go this route, I would serious consider using a proper tubless tyre like the Schwalbe One. If it were me I would get a proper MTB slick and run it with tubes. Much safier option. If you worried about a flat, put some sealant into the tube. Your tube will need the removable valve, but most do have that. As a second thought, will a road tyre even fit an MTB rim. I have my doubts? Hope the helps... Good luck
GoLefty!! Posted February 8, 2015 Posted February 8, 2015 Road tubeless needs a special tyre bead and rim bead hook.

Tankman Posted February 8, 2015 Posted February 8, 2015 Seriously I run tubeless road tyres on my road bike and they need special tubeless rims. I'm not sure the Creast will have the rim structure to run high pressure tubeless tyres. I have converted a normal set of Easton EA70's clinchers to tubeless using the same mtb method. Stans tape, tubeless valve and sealant ... BUT with proper Hutchinson tubeless tyres. Been going for more than two years without issues ... other than replacing the tires after a beer bottle destroyed both. Tubeless tires is key.
Jonkie Posted February 8, 2015 Posted February 8, 2015 I have been using Rubino Pro3 tyres with sealant on tubeless Wheelset for 2 years without any problems.
