ENVE’s new Innerdrive hubs are their first-ever 100% in-house designed hubs, and so they introduce fascinating tech that makes them extra sturdy than prior variations.
The apparent change is a transfer to straight pull spokes, which allowed them to utterly redesign the hub shell and drop 60g from the prior J-bend mannequin. Claimed weight is simply 326g for the pair, however the brand new design permits for stiffer wheel builds with spacing between every spoke in order that they don’t creak or rub on one another.
It additionally makes servicing simpler. Constant spoke lengths on each side of the hub imply you solely want one dimension spoke per wheel.
An anti-twist design make wheel constructing and truing simpler, too, and so they say this improves trip high quality as nicely.
They use stainless-steel bearings and races with non-contact seals on the interior bearings to cut back friction, however full contact seals on the outer bearings for improved longevity.
What’s ENVE Innerdrive?
The actual magic occurs inside, although. They keep on with a ratchet ring design, which they like higher than pawls, however transfer it a number of millimeters additional inboard, deeper contained in the hub shell.
Then they outsized the ratchets to 42mm in diameter and positioned them straight over the interior bearings. They are saying this reduces stress on the axle and bearings by centralizing the torque and eliminating twisting hundreds (and thus put on & tear) on these bearings.
The ratchet rings are comprised of a proprietary hardened metal. Select from 4 tooth counts relying in your most well-liked noise degree and desires:
- 40-tooth (9º engagement)
- 60-tooth (6º engagement)
- 80-tooth (4.5º engagement)
- 100-tooth (3.6º engagement)
All street, gravel, SES, and G Sequence wheels will come inventory with 60-tooth ratchets.
Which begs the query, why supply a 40-tooth downgrade? Most likely as a result of they may license the system to others, so it’s good to have a fundamental, extra inexpensive possibility to extend potential adoption of this know-how.
Good Preload retains it easy
The hubs additionally use their Good Preload system, which eliminates bearing preload adjusters by utilizing a tuned wave washer to supply simply sufficient facet load on the bearings with out stressing them…or leaving it open to consumer error when adjusting (or ignoring) the hubs.
The brand new Innerdrive hubs have been examined below UAE Workforce Emirates all through the 2023 season. They’re obtainable now on SES and G Sequence wheels, and as a standalone hubset for $750. They maintain 24 spokes per wheel and have HG, XDR, MS, and N3W freehub physique choices with 12×100/12×142 thru-axles solely.
