Wheelset 29 "Extralite Straightpull hub | NoTubes ZTR rims MK3 | Sapim CX-Ray | XC MA
intended use of the wheelset: Cross Country / Marathon
That the Italians created to Extralite small CNC art, is beautiful longer known. With the development of Hyperhubs they have outdone themselves. The hub body is extremely complex CNC-machined from high strength aluminum 7075TX. In the rear hub, a pulley freewheeling sitting with 36 teeth. All the intended use Italian brain lard resulted in extralight hub that can fold the technophile mountain bikers & jaw downwards.
Extralite Hyper Front
The Extralite Hyper front hub is a lightweight product that has been improved and developed using modern computer simulation and numerous prototypes. The result is a front hub, which sets standards in terms of lightweight construction and durability. The modern concept of the hub adjacent the organic oversized molding includes the spoke flanges, which are intended for straight spokes. By straight spokes there is a geradliniegeren power flow and from the elimination of the curved spokes head a potential weak point less in the impeller.
Extralite Hyper Boost F 15x110 mm
The Extralite Hyper Boost F hub has been developed especially for the BOOST standard. In detail this means that the hub has an installation width of 110 mm and is clamped via a half shaft with 15 mm diameter in a fork with BOOST standard. Due to the greater width of a higher load is generated at the wheel, which further ameliorate the steering precision with itself.
Extralite HyperWiz 15x110 mm Predictive Steering
Predictive Steering is a new hub Standard of the Rock Shox fork RS1 has been specifically designed. Here, the axle has been extended by 10 mm and dimensioned larger at the end faces. The result is a much verwindungssteifere unit from the hub and fork.
Extralite HyperLefty 2 for Lefty 2.0 / SuperMax
Weighing 85g, it is the lightest on the market hub for Lefty 2.0 and Lefty forks Supermax. It can only spoke with a straight head (Straightpull) are installed.
The filigree Lockring is easy / mounted with a Cassette de-.
Compatible only with Lefty 2.0 and Lefty forks SuperMax.
Extralite HyperRear 2
The HyperRear rear hub of Extralite is easy, nice, reliable, convertible to different Achsstandards. The design of the hub is optimized using advanced simulation techniques and with the organic oversized design provides optimum flow of force in the material. The spoke flanges are designed for straight spokes (Straightpull) to enable also a possible direct and linear power flow. A best optimization was of course operated in the freewheeling mechanism. The freewheel is realized via a toothed wheel which engages directly into a introduced in the freewheel gear. To transfer also high forces safely always intertwine all 36 teeth.
Extralite Hyper Boost R 12x148 mm
The Hyper Boost R rear hub of Extralite sets standards in every respect. Light, beautiful, reliable! The spoke flanges are designed for straight spokes (Straightpull) to enable also a possible direct and linear power flow. A best optimization was of course operated in the freewheeling mechanism. The freewheel is realized via a toothed wheel which engages directly into a introduced in the freewheel gear. To transfer also high forces safely always intertwine all 36 teeth.
INFO: the hub is only compatible with Boost dropouts on the frame. In detail this means that the hub has an installation width of 148 mm and is clamped via a half shaft with 12 mm diameter under. With the MK3 Notubes brings a further development of their legendary Crest rim on the market. Despite a by 2 millimeters enlarged inner width Americans were able to save 20 grams of weight to the rim and at the same time increase the stiffness. Made possible by the inspired by the Valor carbon rims new rim design. With the increased size of 23 mm inner width of the tire increases in volume and is located at low air pressure stable on the rim. After Notubes Wide Right system the width of Crest MK3 has been optimized for 2.0 inch to 25.2 inch tires. For previous version remained the same over the years is the refined Bead Socket Technology and the superior characteristics Tubeless. An extra light rim, the tire can develop fully and the tire volume increases compared to a conventional rim. This leads to a lower rolling resistance and better damping characteristics.
Extralite HyperCamber 2
When HyperCamber rear hub of the drive-side flange on an aluminum spider is extremely vergößert. This feature ensures a flatter angle spokes on the drive side, and thus a more even spoke tension between left and right side of the spoke skeleton. In addition, the stress of the spokes is reduced by acting drive influences. Therefore, the Hyper Camber is especially recommended for larger wheels as 27.5 "or 29". These sizes hyper Camber makes the advantage of better flange geometry of the clearest.
The rims of Notubes are probably the most commonly installed when a spitzenklassiger wheelset is requested with lightweight aluminum rim. The rim profile is optimized such that this wheel takes out a proper stiffness from very little material. In addition, the rim Tubeless ready! This means that normal tires can be driven without tube. For this, the rim must only me provided Tubelesstape and the tires are mounted with some sealing milk. By omitting the tube the friction between tire and inner tube and the flexing of the tube is completely eliminated. As a result, the rolling resistance is reduced while simultaneously increasing comfort and grip!
NoTubes ZTR Crest MK3
intended use: Cross Country, Marathon
recommended weight limit including clothing. 85 Kg (32/32 Hole)
NoTubes Arch MK3 The ZTR Arch MK3 was developed with the input of the Enduro World Series teams. Despite an increase by 5 millimeters tremendous inner width compared to Arch EX, the Americans were even able to reduce the weight of the MK3 minimal and at the same time increase the stiffness. By enlarged to 26 millimeters inside width of the tire increases in volume and is located at low air pressure stable on the rim. After Notubes Wide Right system the width of the Arch has been optimized for MK3 2:25 inch to 2.5 inch tires. Compared to the ZTR Crest Arch EX heavier drivers provides more stiffness and reserves in borderline situations.
intended use: Cross Country Marathon
recommended weight limit including clothing. 95 Kg (32/32 Hole)
Sapim CX-Ray spokes are called spokes. The middle part is butted during production to 1.5 mm in diameter and forged flat in the last step. These processes ensure a strengthening of the structure and bring forth extremely durable spokes.
Wheel building at R2-Bike
Our wheels are assembled by our farmers impeller entirely by hand. While the entire structure is considered important that not only the concentricity true, but also that the spoke tension is as uniform as possible. The special care allows us to give a lifetime guarantee against spoke breakage as long as this was not caused by force!
Furthermore, you get to our impellers following services:
- A universal wheel bag for all standard sizes.
- An extra spoke nipples + to be able to repair the wheel shortly in all required spoke lengths even after accidents.
- A free initial inspection of the impeller, with the resulting work is completely free! There are only shipping.
- A Crash Replacement promise. If you have a wheel damage due to force majeure, we build your wheel on once again. We provide 100% discount on all labor costs and only charge the material!
