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.

 

JOURNAL BEARING SYSTEM

The use of journal bearings, or 'bushings' as some in the bike industry call them, is a perfect solution for the high shock load and abusive limited range of motion that bicycle suspensions put on the pivot system.

Our Journal Bearing system utilizes hard anodized aluminum pivot shafts and Kevlar composite bearings. Since it is not made of steel this system is not capable of rusting and has substantial weight savings over its cartridge style counterparts. Then with the zerk lubrication fittings found at every pivot location, our Journal bearing system has an unrivaled service life, even in the harshest of environments.

The design of our Journal Bearing System is built into the frame to work seamlessly with the suspension. By not using an off-the shelf bearing we are able make use of the entire width of the pivot area. This eliminates any torsional flex in the back end and is why our bikes have legendary handling & stability.

 

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.

 

IMPROVED CABLE ROUTING

In order to make sure that no one had unwanted contact with the bike we created a special machined part to pass the rear derailleur cable directly through the tube on the right side of the rear end.

 

 

MADE IN THE USA

For twenty years now Turner Bikes has been producing American-made aluminum mountain bikes, which is a fact we are very proud of.

We may flaunt it about here and there but this is only the case because we still believe that if we are going to do something, we are going to do it right! Every Turner frame is designed and honed to perfection for one very important purpose; the ride.

44 HEADTUBE

This head tube is perfectly sized to work with a tapered steerer fork and the new 44XX lower head set bearing from Cane Creek. Stiffness gains of up to 20% can be had with a tapered steerer fork. With the upper bearing bore now at 44mm, the rider has the ability to run a ZeroStack headset on top. This setup will lower the hand position up to 10mm for more control on steep climbs and fast descents, where front end traction is enhanced through transferring the riders weight over the handle bar. Our 'just right' head tube design allows for the biggest bearing size on the bottom for a long head set life.

 

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.

 

TRILOBULAR SHAPED TUBES

The new Flux 27.5 is taking everything we have learned from working with aluminum so far to produce a lighter and stiffer ride specifically honed for xc trail riding. This is the first 6061 aluminum model we've made that does not have a tower gusset on the top tube to seat tube junction.

Instead we sat down with our engineers to figure out how we could manipulate the tubing in such a way to have the benefits of that extra gusset but without the added weight penalty. Our new tubeset for the Flux 27.5 uses a two stage forming and heat treating process to manipulate the butted tubing into this 'TriLobular' shaped tubing that accomplishes this goal.
