After five years, Intend have updated their radical Hover shock. The new version is called the Hover Opt, which stands for optimised.
Updates include a one-piece black anodised external shaft, new dynamic seals from Trelleborg, new seal groves, and bushing shafts that are sized for each individual DU bushing.
The Hover's unusual design places the damper in series with the air spring, rather than in parallel to it. This arrangement requires only three dynamic seals instead of the usual four. Nevertheless, Intend decided to switch seal manufacturers to further reduce friction. Intend say the new Trelleborg seals "use a softer PU elastomer material, which, with the same compression, exerts less contact pressure, thereby noticeably reducing basic friction." The new seal groves (which hold the seals in place on the piston) are tighter to reduce something called
seal slap - a jolt or lag which can happen when the shock starts moving into its travel.
The bushing shafts (the cylinders that slide through the shock eyelets and connect the shock to the frame) are now made in six different diameters, varying by 0.01mm increments from 12.70mm to 12.75mm. Intend say that the Igus Z bushings they use have a wall thickness tolerance of around 0.02mm - this is the part that is pressed firmly into the shock eyelet and should rotate freely around the bushing shaft. Intend install the Igus bushing into the shock, then find the bushing cylinder diameter that best fits inside that particular bushing, for minimal friction and no play. If your shock develops play, you can ask Intend for the next size up of the bushing shaft.
It's also available with Intend's Refrigerator cooling fins that are claimed to minimise temperature changes during rough sections, thereby keeping the performance more consistent.
Unlike many high-end shocks, the Hover lacks independent high-speed compression and high-speed rebound adjustability, but each shock is tuned for the intended frame, rider weight and riding style. The price includes one free re-tune if you're not satisfied. Each shock is made by hand in Freiburg, Germany.

Your issue sounds more like the fault of the espresso machine company that came up with a poor seal design and then didn't back it up with good customer service by stocking replacements for the custom seal they specified after making a design change. Not Trelleborgs fault the espresso company didn't order enough seals for replacements, and a small batch run of custom seals will have a high production cost so 5K isn't surprising to me personally.
The fact they would even offer to do a new production run of OEM custom seals for an end-user is honestly not something most of their competitors would do in my experience.
I wouldn't call myself a fan of Trelleborg, but I have worked with them in a previous role on some dynamic custom seal designs for rotary hydraulic equipment, and their solution worked better than any other seal manufacturer we had tried.
*Or "Linear-Pull" brakes, as "V-Brake" was Shimano's trade name.
(Rightfully so, mostly)
Could be argued that most inline shocks put them in series as well, as do pretty much all the Lefty setups. And the few shocks that use bladders instead of IFPs can have 3 or less dynamic seals, but no one really cares.
I never use the lok out and having control of the hydraulic bottom out would been more useful. On a Kavenz btw
Which mounting hardwhere was ordered and what was delivered?
Hey intend start something, at least a service shop state side.
wow! is there anything bad about this shock or brand? what is there to say?
