Turner Bikes DHR
This revision of the DHR bloodline has been broken down into its essential elements and painstakingly rebuilt with every minor detail polished to stunning perfection. Now with a thirteen year long lineage, the new DHR gains the use of the dw-link and such features as centralized & lower center of gravity, postmount disc brake mounts, 1.5 inch headtube and an anodized & laser etched finish. This purpose built, world cup downhill race bike will outperform anything else in its class.

Geometry Key

* Inseam measurements are fine for pant shopping, but have no place in mountain bike shopping. Leg length is what is important as rarely does anyone buy pants that have the same inseam as their actual leg length. Since no one rides barefoot the leg length should be measured with your mountain bike shoes on standing against a wall and with a carpenters square or large sized book firmly raised into the crotch and square to the wall is how to figure leg length.

Turner Bikes measures ‘Standover’ height 6” / 150mm in front of the BB center, that is roughly the MIDDLE of the Top Tube, not at the actual lowest point way back at the junction with the Seat Tube as some companies do. The allows for plenty of standover clearance without the nose of the seat crushing into your spine!

Geometry Key

A: Seat Tube Length - Is measured from the center of the bottom bracket to the top of the seat tube collar.

B: Head Tube Length - Is measured from the bottom edge to the top edge of the head tube.

C: Stack Height - Is measured along a vertical line from the center of the bottom bracket until it intercepts the imaginary Reach Length line.

D: Reach Length - Is measured along a horizontal line from the center of the head tube until it intercepts the imaginary Stack Height line.

E: Stand Over Height- Is measured from the ground along a vertical line to the top of the top tube 6” / 150mm in front of the BB center, that is roughly the MIDDLE of the Top Tube.

F: Head Tube Angle - Is measured from a line along the head tube and a horizontal line parallel to the ground.

G: Chain Stay Length - Is measured from the center of the bottom bracket along a horizontal line to the center of the rear wheel axle.

H: Bottom Bracket Height - Is measured from the center of the bottom bracket to the ground.

Features ::.
dw-link //
Simultaneously engineered anti-squat and wheel rate curves are the mathematical formulas that make dw-link the world's most efficient and traction-aiding suspension system.

The dw-link is the only design on the market that is able to control unwanted bob and still remain active in more gear combinations than any other design. Dave Weagle has been refining the mathematics of optimum pivot locations of the dw-link on everything from World Cup winning downhill bikes to short travel XC flyers.
finite element analysis (fea) //
A mathematical technique for analyzing stress points, which breaks down a physical structure into substructures called 'finite elements'. These finite elements and their interrelationships are then converted into equation form and solved mathematically.

We use an FEA computer program to aide in the design of every Turner frame. This helps us maximize the strength and minimize the weight to insure a perfect balance is acheived as form follows function is the convention we adhere by.
anodized frame finish //
Due to the tough nature of anodizing and the permanence of lazer etching it fits well with the extremely long life riders get out of their Turner Bikes.
enduro max-type bearings //
With the tight space constraints to allow the dw-link to behave optimal, remain fully active and have incredible lateral rigidity under load, the DHR uses enduro max-type bearings since they have been proven to work in a smaller compact design. Then with the aide of triple seals and Zerk lubrication fittings, this system raises the bar for world cup dh racing potential. The design of the new DHR has been refined and tuned to deliver the best handling feel and shock performance imaginable.
mass centralization //
Our DHR has been designed to carry the majority of its weight as low and close to the bottom bracket as possible. This incudes lighter butted & tapered stays, compact dropouts, post-mount brakes, and so on to reduce the weight at the extremities of the frame.

This is done to accomplish two main goals. One is to build a super rigid chassis to provide lightning quick trail response. The other is to keep the bulk of the frame weight centered and as low as possible to improve stability and handling. The result is a down hill frame design that is even faster and more agile than any of its predecessors. Railing corners and floating over rock gardens has never been this effortless.
butted & tapered stays //
The chain and seat stays on the new DHR are Butted and Tapered. This feature reduces the swing weight of the rear end for improved handling and enhanced shock performance.
post-mount disc brakes //
The biggest reason why Turner Bikes chose to pioneer the use of post-mount rear brake mounting was to eliminate the adapter. All disc brake manufacturers and all new fork designs had already gone to the post-mount calipers due to the ease of set up and the increased rigidity provided. Plus, with the decision to create the post-mount rear dropout we removed two bolts that were doing nothing but adding weight and potential flex. An exceptional design begins with simplicity and commonsense.
threaded zerk grease fittings //
Zerks are stainless steel, ultra compact, custom made proprietory fittings to aide in the lubrication and maintenance of all the pivots on a Turner frame. It only makes sense that a machine that is used in the rough and many times sees wet conditions, that it would have a way to push the grit and water out easily and on regular basis. This is one of the key features that makes the ownership of a Turner cost effective over the long haul.
