UK-based Hunt Bike Wheels – famed for making high-end and affordable wheels for road, cyclocross, gravel and mountain bikes – also owns Privateer Bikes, and has today announced pricing for its first complete bike and frameset.
Privateer is founded on the principle of making bikes that have got race-ready geometry and features that are developed around the specific needs of racers that are able to stand up to a season's worth of racing abuse.
To top off that rather demanding brief, it also wanted to produce bikes that privateer racers could afford, and it has delivered with the 161, coming in at £2,989 for a very tasty looking build.
Privateer Bikes 161 frame details
First seen between the tapes of the Enduro World Series in 2019, ridden by British pinner Matt Stuttard, the bike had been in the prototype stage for around 18 months prior to its first top-level competition appearance.
Alastair Beckett – most famous as one of the guys behind Nukeproof's hugely successful Mega enduro bike – helped develop the 161's visual design, geometry and suspension.
Privateer says that rider feedback was crucial during the bike's development, with the brand focusing on creating an enduro rig that can descend as fast as possible while maintaining low-effort climbing prowess.
It claims that by reducing stress and fatigue on the body from climbing, more energy can be spent on the downhills. With that in mind, the 161 is truly aimed at gravity-orientated riders.
The frame is built from 6066 T-6 aluminium tubes in Taiwan by "industry-renowned" welders, and has a simple yet fairly sleek aesthetic, complemented by a raw brushed aluminium or matt black finish.
It has externally-routed brake and gear cables to help simplify cables changes and brake bleeds or swaps. The dropper post cable is internally routed, entering the down tube just behind the head tube.
The main pivot features three bearings: two on the driveside and one single bearing on the non-driveside.
The rocker link that compresses the metric-sized Trunnion shock from above is made from one piece of material that, Privateer Bikes claims, should improve frame alignment and bearing life while increasing stiffness and strength.
The bike features a standard 73mm threaded bottom bracket and ISCG05 chain guide mounts. It has a 52mm chainline with a 3mm offset and can run up to a 34-tooth chainring. The Q-factor is 168mm.
The 12mm rear axle has Boost 148mm spacing, there's a tapered head tube and a 31.6mm seat tube diameter.
Privateer Bikes claims the P3-sized frame weighs 3kg without shock.
Back to the drawing board
During the development process, the industry's increasing appetite for longer travel dropper posts became a concern for Privateer Bikes.
With its linkage pivot placement, it wasn't possible to insert a long-travel dropper post far enough into the seat tube to make it practical to use.
Instead of carrying on with the production of the bike and asking customers to compromise with shorter travel droppers, Privateer Bikes decided to revisit the 161's seat tube, bottom bracket and down tube design to see how it could allow for deeper dropper insertion, while retaining its desired suspension kinematic.
After a redesign of the BB and lower shock mount area, and thanks to some clever CNC machining, it managed to increase dropper post insertion by 50mm on its smallest 'P1' size bike and 80mm on its larger P2, P3 and P4 bikes.
This change nods to an overall rider-first design philosophy that we can really get behind.
Privateer Bikes 161 suspension details and performance
Built with 161mm of rear-wheel travel, the Privateer Bikes 161 uses a 205mm eye to eye Trunnion rear shock with a 65mm stroke.
The suspension's kinematic is designed with both coil- and air-sprung shocks, although the frameset is specced with RockShox' SuperDeluxe Ultimate DebonAir air-sprung shock.
The 161 uses a Horst-link style suspension system seen on other bikes such as Specialized's Enduro, Nukeproof's Mega and Whyte's G-170, plus plenty of others.
Like other Horst-link bikes, the 161 has a low anti-rise figure peaking at just below 50 per cent around 70mm into the bike's travel, where the suspension's ability to resist compression is greater than the compression forces created during braking.
It's got high anti-squat figures sitting between 142 per cent and 132 per cent at sag point, dropping to 82 per cent at bottom out. This, in theory, means the bike should pedal well.
Finally, its leverage ratio is progressive overall with a small hump at the start of the travel.
This means the very initial part of the travel will be slightly harder compared to when it's between five and 20mm into its suspension. From then on it gets linearly harder to bottom out, giving an overall progression to the curve.
The rear wheel's axle path features a short rearward 3mm arc from full extension up to 50mm into its travel, then curving forwards from -3mm to +13mm until bottom out.
It's generally considered that the more reward a bike's axle path is, the better it is at absorbing bumps.
Privateer Bikes 161 geometry and sizing
The 161 comes in four sizes and is claimed to fit people from just below 160cm tall up to people well over 190cm.
The smallest size bike is designed around 27.5in wheels, while the next three bigger sizes are built around 29in wheels.
Like an increasing number of brands, the four sizes are focused around increases in reach measurements rather than seat tube lengths. The reach figure grows from 445mm for the smallest bike up to 515mm for the largest.
The seat tube length only changes by 80mm across sizes, starting at 400mm and finishing at 480mm.
Each size has its own chainstay length, once again growing as the bike's overall size increases. This is a popular move that many other brands tend to ignore, keeping their chainstay figure static across size ranges.
The head tube angle sits at 64 degrees across the sizes, as does the effective seat tube angle that's a mind-bendingly steep 80 degrees. Actual seat tube angles hover around the 75-degree mark across sizes.
Privateer Bikes recommends the 27.5in wheeled bike runs a 37mm fork offset, while the 29in wheeled bike should run either a 42mm or 44mm offset.
