The Turner 5.Spot. revolutionized the trail bike class in 2003 and now, ten years later, it continues to raise the bar for unparalleled ride quality. With the addition of the dw-link and then the updated trail geometry, the 5.Spot pedals like a xc rocket while still handling like a gravity built machine. Never has the pendulum been swung so far and still remain so perfectly balanced. Now new for version 4.2 is the 142x12 Thru Axle, ISCG 05 Mounts, new cable clamping system (no more zip ties) and increased Shock Clearance. And then along with the 44 Headtube, post-mount disc brake mounts, Journal Bearings, and Zerk Lubrication Fittings the Turner 5.Spot is the epitome of what a trail bike should be.

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: Effective Top Tube - Is measured from the center of the head tube to the center of the seat tube along a horizontal line parallel to the ground.

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

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

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

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

F: 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.

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

H: Seat Tube Angle - Is measured from a line along the seat tube and a horizontal line parallel to the ground.

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

J: 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.
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.
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.
burrito vs. taco //
Moving into 2011 we created a custom drawn, differentially dimensioned tube to replace the taco shell style seat tube/ top tube gusset of the past. This design will spread the load across the top tube and seat tube more efficiently with its convex top surface. This is due to the shape and varying wall thickness of the burrito to control how the stress is dispersed through the frame.
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.
