I am adjusting my tire pressure and only recently moved to Tubeless. I ride Pirelli P Zero Race on Syncros Capital 1.0 50 (on Scott Foil 2020, if that matters) and trying to figure out if (1) my wheels are hookless or not to figure out (2) max pressure. (Silca’s calculator puts me over the 75 PSI m…

There’s no way I would go back to riding the pressures Silca recommends for me. The ride quality suffers too much. I find Zipp pressures much more to my liking.

I’ve been using hookless 23 IW with 30mm tires or wider, I wasn’t concerned initially. However, the recent incidents and the response from manufacturers leave a lot to be desired. Low tire pressure shouldn’t be an issue. As mentioned above, for most people 73 PSI is above the recommendation for opt…

Giant does a lot of testing, just make sure you use tires on there approved list

[image] Ahmad: Have there been many blowouts before? It’s not many. It’s small percentages but too high of a percentage when a blowoff while riding might mean crash and/or injury. Plus we’ve yet to see any tangible benefits to the consumer. They claim cheaper but if it’s $20 per rim, the sav…

Yes it has happened to me (except my case is too much PSI in a gravel configuration, same concept different situation). [image] Blew My Tire Right Off My rim! Equipment I like to think I am pretty mechanical and technically savvy… That doesn’t mean I cant or wont royally…

[image] ABG: Giant does a lot of testing, just make sure you use tires on there approved list Fair, and I will definitely follow their approved list. Their support page also includes a helpful “Tires I should not use” list ( Giant Hookless Technology | Giant Bicycles US ). What is NOT helpful …

Interesting fair enough. I guess the next obvious question…is the blowoff rate significantly worse than with hooks, or even with tubes on standard rims? I don’t know the answers…I wouldnt even speculate. Just saying that nothing is ever perfect…

I am not saying it isnt possible, but I have not had a tire blow off a hooked rim. I run my current tubless road tires that are hooked with a 21mm ID and 25mm continental tires at 85psi R and 83psi F respectively and do not have issues with them.

Hookless or not?
