The Re4mer is Tune's new full carbon saddle. It is characterized by rounded edges and a flat, slightly butted and closed nose. It is also covered with Alcantara leather. The R4mer weighs just 79 grams and should offer sufficient seating comfort even on long rides. Thanks to the rounded edges, the saddle is also ideal for mountain bikes.

The predictive steering hub for Rock-Shox RS1 forks "Princess Skyline PS" is not only unbeatably light at 136 grams. With an oversize axle of 27.5 millimetres and special ball bearings, it is also very stiff. There is also the new "King PS" for the predictive steering axle system from Rock Shox. At 153 grams, this weighs only slightly more.

Tune already relies on straightpull hubs, which are used exclusively with non-cranked spokes. The "Prince Straight", "Princess Skyline Straight" and the "Cannonball 2.0 Straight" expand the portfolio of this type of hub. The advantages of straight spokes are a material-appropriate load on the hub flanges and direct force transmission of the drive and braking forces via the spokes into the hub body. This ensures even more direct torque transmission and eliminates the delays that can occur due to minimal deformation. This should raise the stiffness and responsiveness as well as the durability of the Tune wheels to a new level.

However, the new "Boost" axle standard is also taken into account. The "King" front hub and the "Kong" rear hub come in Boost installation widths of 110 and 148 millimetres. They differ fundamentally in some points from the 100, 135 and 142 millimeter installation widths. The Boost standard enables complete adaptation of the hubs with wider hub bodies and axles. Unfortunately, it is therefore not possible to convert existing hubs to the Boost standard. Nevertheless, the new standard offers some advantages:
The flange distance increases for both hubs. This allows stiffer wheels to be built, which is particularly noticeable on twentyniners. One criticism of large wheels has always been their lack of stiffness. Thanks to the larger installation width of Boost hubs, 29-inch wheels can now be produced that are on a par with the smaller ones.
Despite the wide bearing support, Tune is able to keep the weight of the "King Boost" at just 121 grams and that of the "Kong Boost" rear hub at a fairly low 214 grams.

The tried-and-tested Würger Skyline saddle clamp has been revised and a completely new clamping principle has been developed. The result is better and gentler power transmission. A new design makes the new "Würger Skyline" a discreet eye-catcher. The filigree saddle clamp grips where power is needed and is also designed for the toughest load tests.

One of the hottest shifting systems are Shimano's XTR and Dura-Ace Di2. The battery for these electronic drivetrains is also available in a round version for mounting in the seatpost. So far, however, you either need a seat post with a special mount or you have to tinker with construction foam. For round seat posts without a special mount, Tune now offers the first clean and simple attachment for the Di2 battery.

"Energy carrier" is the name of this little helper. It is used to attach the Di2 battery easily, quickly and securely to round seat posts. It consists of two aluminum plates, two screws and a silicone ring. At around eight grams, the "energy carrier" weighs slightly more than a piece of chewing gum and is almost as easy to use: Put it on the battery, slide the battery into the seat post, tighten the screws slightly - done. The energy carrier only touches the seat post with the silicone ring, so leaves no scratches. The technology is based on Tune's GumGum headset clamp. "Energieträger" is available for diameters of 27.2, 30.9 and 31.6 millimeters. In typical Tune fashion, it weighs a mere eight or ten grams.

And this is how the energy carrier works
