Wheelset 27.5 "| 650B Hope hubs | BOR AMD 444 Rims | Sapim CX-Ray | TR AM
intended use of the wheelset: Trail / All Mountain
With the Pro 4 Hope heralds the latest evolution of its hub. The already well-known for their quality workmanship and indestructibility hub was further to stiffness and durability, improved ways.
HOPE hub front Pro 4
It has a larger flange diameter than its predecessor and still allows thus stiffer wheels. Known features like the multiple colors available, the sealed stainless steel bearings and interchangeable end caps have been retained. Also the weight has remained.
Using optional end caps the hub at any time on quick release, quick-release axle 9mm, 12mm thru-axle, quick release axle 15, 20mm thru-axle can be retrofitted.
HOPE hub front Pro 4 | Boost 15x110 mm
The Boost version has a wider body than the hub QR15 variant. For her, the flanges are moved to each 5mm outward, optimizing the angle of the spoke to the rim, thus enabling significantly stiffer wheels, resulting in a significant performance gain especially in 29 "wheels. In addition, the clamping surface on the fork is larger and allows enormously stiff connection between the fork and wheel.
HOPE hub rear Pro 4
It has a larger flange diameter than its predecessor and still allows thus stiffer wheels. The freewheel gear now has 44 teeth, or 10% more locking points than the previous model. This results in a free travel of just 8.2 ° when accelerating.
Even the freewheel body has been completely redesigned and now comes with two, rather than three, bearings made. In order to ensure the durability of these larger dimensions.
Known features like the multiple colors available, the sealed stainless steel bearings and interchangeable freewheels / end caps have been retained.
Using optional end caps the hub at any time on quick release, 10mm thru bolt, 10mm are screwed, 135 x 12mm, 142 x 12mm convertible.
HOPE hub rear Pro 4 | Boost 12x148 mm thru axle
The Boost version has a wider hub body than 135/142 mm variant. For her, the flanges are moved by 3 mm to the outside, which optimizes the angle of the spoke to the rim, thus enabling significantly stiffer wheels, resulting in a significant performance gain especially in 29 "wheels.
BOR AMD 444
The AMD 444 rim completes the range with BOR a lightweight All Mountain / Trail rim. It relies on old virtues, as the asymmetry and simply exported stainless steel loops, which provide better force against the nipple seat.
Is extended this concept to a grown to 24.7 mm inner width that can better stand on the rim of the tire. The carcass sits characterized wider and thus substantially straight on the rim, which also increases the volume of air. A premature buckling of the tire is prevented. You can go so with less air pressure, what the grip level increased significantly without having the feeling that the tire on the rim drumming.
By Asymmetric profile an almost identical spoke tension on the left and the right permits and prevents bending of the spoke nipples, providing ultimately a stable and durable wheel.
Of course, the rim can be driven with a matching tubeless kit and corresponding tire without a tube.
intended use: Trail, All Mountain
recommended weight limit including clothing. 90 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!
