Pro 4 hubs
As a direct development of the successful Pro 2 EVO hub, the Hope Pro 4 hubs bare a lot of attention to detail. The freewheel now has a 44 tooth ratchet mechanism which provides a 10% quicker hub engagement over the Pro 2 EVO. The flange diameter has been increased, adding more stiffness to larger wheel builds – even with non Boost with hubs. The new Shimano compatible freehub will be prepared to accept 11 speed cassettes. A lot of effort has been spent to guarantee compatibility, both on axle, but also on freehub possibilities. You can switch between the different conversions without needing complicated tools.
Specific hub shells are available for this wider standards, but there’s also the possibility to convert an existing hub with disc spacers and endcaps. Since the drivetrain is moved 3 mm to the right, boost specific spiderless chainrings and spiders are needed. The chainrings are Hope crank specific and available in 28, 30, 32, 34 and 36T.
High range cassette
Finally available as from January 2016, the new Hope cassette offers 10 or 11 speed gear ranges. The smaller 7 speeds are made out of a one piece hardened stainless steel cluster (which is the same as the short DH cassette). Depending on being 10 or 11 speed, the larger 3 or 4 sprockets are made out of a one piece aluminum billet. The steel cassette should last longer, as you can replace the aluminum sprockets. Sizes: 10-40 10 speed (250g), 10-40 11 speed (273g) and an impressive 10-44 11 speed (284g). All versions are claimed to have 20% ratio changes.
