EXTRA LITE wheelset 27.5 "| 650B HyperCamber | NoTubes ZTR Crest
These hubs, which highly optimized designs using modern computer technology are possible. Extralite developed the hub by means of simulation programs and all kinds of knowledge and reaches constantly new weight records. Here no loss in stability and durability to be accepted! The bearings used have sealing washers, which are supported by an external dust cap and rubber gasket. This double seal system exceeds its effectiveness many, much heavier hubs on the market!
The HyperRear 2 has an improved seal between the hub and freewheel which brings about a better sealing effect and at the same bleibener, low friction. The freewheel is realized at Extralite via a toothed wheel made of aluminum, which engages directly into the teeth of the freewheel body. The integrated construction of the mechanics also saves considerably weight.
If these teeth become worn, it is possible a new pulley employ slightly offset and thus to double the service life.
The Crest rim of Notubes is probably the most built-up rim when a spitzenklassiger wheelset with a lightweight aluminum rim is requested. 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 nut provided me 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!
