Here you can find all the technical data and the test results for the SRAM Roam 40 27.5" wheel.


Price / Info 618 Euro www.sram.com


Description of the Aluminium rim, 24 double-crossed blade spokes (2.5-1.0 mm), pawl freewheel, incl. quick release, valves


Available diameters 26", 27,5", 29"


Available brake mount 6-hole


Available front axle standards QR¹, 15 mm, Boost


Available rear axle standards QR¹, 12 x 142 mm, Boost


Max. tyre width Tyre width No restriction


Max. Rider weight/disc size no limitation/200 mm


MEASURED VALUES


Rim width (inside) 21 mm


Weight² VR 765 g/HR 889 g/total 1653 g


Stiffness VR 62 N/mm / HR 61 N/mm


Inertia VR 433 kg x cm²/HR 432 kg x cm²

Spoke tension deviation fron. left: 28 %, fron. right: 41 %, hi. left: 23 %, hi. right: 11 %


Concentricity/centredness new condition (points/max. points) 6/10


Resistance to overload (points/max. points) 10/10


Conclusion At just 21 millimetres, the Roam wheels are the narrowest and therefore weigh very little. The largest deviations within this test group can be found in the spoke tension.


BIKE judgement³ VERY GOOD (359)


¹QR stands for Quickrelease = normal quick release.
²Weight without quick release and including rim tape.
The BIKE judgement is independent of price. BIKE judgements: super (510-380 pts.), very good (379-330 pts.), good (329-280 pts.), satisfactory (279-230 pts.), with weaknesses (229-180 pts.), unsatisfactory.
