Hi all,

I am able to get me hands on a pair of new tubular Cadex 65 wheels (rim brakes) at a very affordable price but I am concerned about the safety of the hookless & tubular combination considering my weight (188 cm - 79 kgs) and the pressure limit set by ETRTO for hookless rims. I don't mind the hassle with the tubular tape etc etc.

Any help here is appreciated.

Thanks!

Tubulars are hookless by design, there is no hook holding the tire. Glue is used to keep the tire in place.

Tubulars are safer than clincher or tubeless, they don't pinch or unseat and can be run flat(if you don't mind damaging the rim)

I think the op is confused. Cadex make a tubular rim brake wheel and a tubeless, hookless rim brake wheel. He has combined the two.

You can run whatever pressure you like on a tubular wheel.

I have looked at the Cadex 65mm hookless rim brake wheels for my Propel, but decided they are a slightly ill formed idea.

I would need to use them with 25c tyres, which makes the max 73psi pressure insufficient and the risk of a blowout when the wheels heat up from braking on descents would be unacceptably high.

Needless to say I'm am sticking with tubulars for now.

If you want to use the Cadex 65 wheels, you need to make sure that your tubular tyres are compatible with hookless rims and that you do not exceed the recommended pressure.

you CANNOT use tubulars on hookless, only tubeless that are made for hookless

LOL if you glue your tubular tyres to hookless rims you'll most likely end up needing to buy new rims after 500 meters of riding. :lol: :lol: :lol:

Spend 5 minutes with Google and don't get the two types of tyre mixed up please, they are really really different.

The problem is tubular and tubeless sound similar and to non native English speakers it's where the confusion lies.

Man hookless + rim-brake is an odd combo.

Thanks for all your replies.
From what I've seen, a tubular rim is by definition hookless which makes sense since tubulars do not have any bead as the inner tube is stitched to the tire itself.

Will I now be the only one running tubulars and rim brakes? Even if it's a little outdated, I believe it should still work well.

Tubular is 'hookless' because glue or double sided tape is used to secure the tyre to the wheel. Please tell me you understand this.

Yep I already mentioned that in the initial post 👍

1000s of people run tubulars. Many of us buy and ride older bikes and wheels

I had to go to their website to see if that was an actual offering...

Maybe I'm getting old; I ran carbon tubeless rim brake wheels(hooked to be clear) for about a year before going disc, and now the thought of that kind of sketches me out. Add in another variable of hookless, and it just seems like a recipe for disaster... When a tire is hard to mount, what do you do? You set it in the sun to warm up and thus making it easier to stretch the bead onto the wheel. What happens when you're braking heavily on a rim brake hoop? It heats up, and more than likely some portion of that heat is dissippated into the tire...
