Q: What size seatpost is required?

A: 2011 dw-link DHR's use a 30.9mm seatpost with enough length to guarantee 4" or 100mm of insertion.

2008 DHR's and prior use a 27.2mm seatpost.

Q: What chain guide do I need for my DHR?

Q: What size is the bottom bracket does the DHR use?

A: The DHR has a 83mm bottom bracket shell with english threads.

Q: How big a tire can I run on the DHR?

A: The DHR has the ability to run tires up to 2.5" with ample room for bent rims and mud clearance. This suggestion is due to variations in tread design, tire sizing and rim widths. Although larger tire sizes may fit properly but due these case by case situations it is up to the rider, or dealer, to install an acceptable tire size.

Q: What fork travel length do I need for my DHR?

A: For the DHR, the suggested fork travel length is 180-203mm.

Q: What is the rear wheel spacing?

A: The rear hub needed for the DHR has a 12mm x 150mm dimensions. The rear is Saint compatible.

Q: What size headset do I need?

A: 2011 dw-link DHR's use a 1.5" headset with 15mm of insertion into the headtube. The headtube is deep reamed and will fit a 1" deep skirted headset. Zerostack lower cups are NOT recommended, a standard lower heaset cup is prefered.

2007-2008 'Round-Tube' DHR's use a 1.125" headset.

2004-2006 'Square-Tube' DHR's use a 1.5" headset.

Q: Torque Wrench Specifications for my DHR is?

A: These Torque Wrench Specifications apply to the dw-link DHR:

• Upper Link- 17 ft-lbs / 23 nm / 204 in-lbs.

• DW Link- 17 ft-lbs / 23 nm / 204 in-lbs.

• Shock Bolts- 11 ft-lbs / 13.7 nm / 130 in-lbs.

If this is at all confusing please consult your local Turner Dealer for the proper mechanical procedure and tools. Please refer to our Turner Tech page for more information on proper bike maintenance.

Q: What is the dw-link?

A: 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.

Q: Why use Enduro Max-Type Bearings on the DHR?

A: 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

Q: What is a Zerk?

A: Zerks are fittings that 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.

Q: Why use the 'post-mount' standard to attach disc brakes?

A: 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. With the decision to create the post mount rear dropout we eliminated the adapter and two bolts that were doing nothing but adding weight and potential flex. Thus it is stronger, lighter and simpler, seems like a no brainer in hindsight.

Q: How do I setup my FOX RC4 shock for the dw-link DHR?

A: These settings can be used as a starting point across the boards, regardless of rider weight.

KEEP IN MIND THAT THIS IS FOR THE 2011 RC4

* BV pressure: 140 psi
* HSC: -10
* LSC: -12

SPRING RATES:

~170lb rider: 350 spring
* REB: -7

~200lb rider: 400 spring
* REB: -5

The faster you ride, the more energy you are putting into the bike. Faster riders will need to add spring rate. Slower riders can decrease spring rate. Depending on your riding style you may find that you want to change the spring rate. Being honest with your assessment of yourself as a rider is the first step to getting your bike set up for you.

To increase support early travel, decrease spring rate and add preload.

To increase support end travel you can either add BV pressure or increase spring rate and decrease preload.

BOOST VOLUME (via bottom-out control):
I do not recommend changing the boost volume to anything lower than full open, as the dwDHR has ramp built into it's leverage ratio.

LSC:
Unless you pedal like a gorilla, really getting your hips into the action, you shouldn't need any additional LSC.

HSC:
These settings were based on a rocky East Coast test track. If you are on a smoother track with bermed corners and less square edges, you can increase HSC. If you are riding at World Cup speeds, you can increase HSC. If you feel the bike slowing down through rocky sections, you may be running too much HSC.
