The ongoing hookless rims saga
Hookless rims - the solution to a problem we never had

Hansen said that there were even bigger issues in the past when teams used hooked rims with hookless tires, something he described as “an even worse disaster.” I never heard of a hookless tire? |

Not a great endorsement for those foam liners either. My understanding is the hookless is basically held on by the air pressure so when the pressure drops.......bye bye tire?

There are hookless tires?

In the February 9th edition of the Escape Collective's Performance Process podcast, guest J.P. Ballard of Swiss Side (maker of aerodynamic bicycle wheels and other components) said that he has seen tires blow off hookless rims, even below the maximum allowed pressures, and that is why Swiss Side will never make hookless rim wheels. He also poo-poo-ed the idea that hookless rims provide any performance advantage to cyclists, the only advantage is that they cost about $20 less to make per wheel.

There are tubeless tires rated for use with hookless rims, but not all tubeless tires are hookless rated. I had early model Michelin tubeless that were not hookless approved. I used them hookless, but the bead stretch after a year caused them to unseat when the air was let out to check the sealant level. With the valve core in, I couldn't get air in fast enough to seat. No such problem with Pirelli P-Zero TLR. I put an old one on with a tube for a few rides and had a hard time getting it off the rim. Some soapy water and a lot of pushing finally unseated the bead.

The people that are interested in pushing this are trying to spin all sorts of nonsense about how hooks are redundant and benefit the consumer - I am not buying it, at least not yet, and not from the same industry that thought press fit 30 and shoving cables through headsets is a good idea - its all cost savings on the manufacturing end, nothing else.
Its really not ready when the margin of error is less than the accuracy of most floor pumps, or you have to get out a spreadsheet to determine tire and wheel compatibility. Lawyer tabs, limit screws and brake pad retaining screws/pins are also redundant, but there's a reason they all exist. |

Every time I read one of these threads (hookless rims/tubeless tires for paved road riding), I smile and think how glad I am to be riding conventional clinchers on hooked rims. No fuss, no drama, and very few flats. Am I giving away a few watts to more “modern” tubeless setups? Sure. But apparently not enough watts to keep me off masters podiums. My mantra: to finish first, you first must finish.

True or false: There are no hookless rim brake rims ?

Well, Cadex has two hookless rim brake wheel sets:
Cadex 42 Tubeless wheels Cadex 65 tubeless wheels |

Some Internet forums I frequent have a culture of keeping threads on recurring topics alive - so instead of creating a new thread on the hookless topic (of which there are…. a lot… all of which have the same argument in them) you just bump the old one to the topic.
Makes the forum more manageable. Oddly this does happen here, but only for the Campagnolo Ekar thread, for some reason. Just a thought. Hookless mountain bike rims are completely fine. Can’t say I’ve used them at high pressures but my desire to ride tires less than 40mm wide is nil at this point. |

tubulars - the original hookless rim!

Hookless rims are cheaper to manufacture so you can expect the industry to start pushing them more. I can't even begin to understand hookless tubeless rims.
