Are these the lightest disc brake hubs? Tactic TR01 (aka Princeton Carbon)

Seriously, I'm not sure how anyone would be comfortable with a hub that's lighter than a rotor but somehow these guys claim their new hubs at a combined weight of 215g for a set are as durable as more established players.

Any thoughts? Seem like pros and schmoes alike love their wheels so at least the track record is strong.

Using aluminum alloy for their ratchet ring seems kind of risky?

Surely, one would hope when it's been made for and tested by Ineos, it would be strong enough to hold up? At that price too, I'd be pretty surprised if it was low grade material.Matt28NJ wrote: ↑Fri Dec 17, 2021 1:40 amDepending on the grade of aluminum, it may be very soft.MarginalChains wrote: ↑Fri Dec 17, 2021 12:53 amRookie question perhaps, but why is that?TobinHatesYou wrote: ↑Thu Dec 16, 2021 10:12 pmUsing aluminum alloy for their ratchet ring seems kind of risky?

They have a crew of mechanics, spare wheels and likely spare ratchet rings in case of failure.
Aluminum alloy HG freehub bodies get chewed up. Titanium and steel ones don't. Now there's more points of engagement in the star ratchet, so maybe it's fine??

Replaceable? Yes. This is the case with most high-end hub ratchet rings.
...and your entire pedalling force gets transmitted through the few grams of metal constituting the ratchet ring.Matt28NJ wrote: ↑Fri Dec 17, 2021 1:40 amDepending on the grade of aluminum, it may be very soft.MarginalChains wrote: ↑Fri Dec 17, 2021 12:53 amRookie question perhaps, but why is that?TobinHatesYou wrote: ↑Thu Dec 16, 2021 10:12 pmUsing aluminum alloy for their ratchet ring seems kind of risky?

Yes, i know they are replaceable, one made out of aluminium is likely to be a consumable. Hopefully they include a couple of spares and the tool in the boxTobinHatesYou wrote: ↑Fri Dec 17, 2021 12:04 pmReplaceable? Yes. This is the case with most high-end hub ratchet rings.

Likely a calculated decision then; I suspect most of the target market won't mind replacing the free hub body from time to time in return for the weight saving. Either that or their team mechanic looks after it all for them...
I had a freewheel slip once, crashed, the guy behind me was left laying the road with a broken hip.
So, when do you replace this 'wear' item? When it's worn out? Might be too late and someone will be left in the road. Regular maintenance? Sounds costly to me. I like technology and I do understand that engineers understand that soft aluminum is not a place for this ratchet. I would not be the first to buy and be waiting to see if the storm is brewing or not. Heck, I would have to buy a disc brake frame first.
Plus the fact, when one of the first complaints that it's loud, I'm out. Loud is not a selling point for me. Yes, I know there are plenty that like it and I can respect your opinion with that.

i always like the idea of having more choices, even one that i cant afford, because this paves the way for next gen lower price options.
the design so far seems to suggests that they accepted the freehub body is part of the consumables since half of the ratchet system is also freehub body. this integration no doubt help reducing weight but as others have said, reliability remain to be seen.
i read the cyclingtips article, although it mentioned a few times about bigger bearings, the article never specified which ones. would be interesting to find out.

Some say pour 10ml water out of your bottle to save that last bit of the weight. Sorry, i go one step further, i tend to the rider off my bikes.
