Flux 27.5 FAQs
Q: What front derailleur do I need for my Flux 27.5?
- A: All dw-link Turner's use a 34.9mm, Top-pull, Bottom-swing, Traditional Clamp.
Top-swing will NOT work. All Dual-Pull derailleurs must be modified, due to the bottom-pull arm as it will contact the chainstay yoke under full compression. Go to our tech page for information on how to modify Dual-Pull derailleurs.No modification is needed for the following derailleur(s): SRAM X9, Top-pull Only, # 00.7615.014.000
Q: What fork length do I need for my Flux 27.5?
- A: For the Flux 27.5, the suggested fork travel length is 120-140mm.
Q: What size seatpost is required?
- A: 30.9mm seatpost with enough length to guarantee 4" or 100mm of insertion.
Pre-2009 Turners, horst-link or TNT, use a 27.2mm seatpost.
Q: My seatpost goes in but stops before the seat is all the way down, is this normal?
- A: Yes, Since most seatposts are longer than 8 inches in length. The Flux 27.5 seat tube is reamed to accomodate a total of 8 inches of seatpost insertion. Only lower your seatpost to the point where it stops, forcing in past this point will only damage your components.
Q: What size headset do I need?
- A: The Flux 27.5 uses a 44mm headset size. This allows you to run a straight 1 1/8" steer tube or a tapered style steer tube. For more information on 44mm headset configurations please refer to either this Chris King 44mm Fit Guide or this Cane Creek 44mm Fit Guide.
Pre-2012, use a 1 1/8" headset with 8mm of insertion into the headtube.
Q: What size bottom bracket does the Flux 27.5 use?
- A: The Flux 27.5 has a 73mm bottom bracket shell with english threads.
Q: How big a tire can I run on the Flux 27.5?
- A: The Flux has the ability to run tires up to 2.3" 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 sag should I run in the rear shock?
- A: Proper sag on the Flux 27.5 is 11-13mm. Please refer to our Turner Tech page for more information on proper shock setup.
Q: What Size shock and hardware does my dw-link Flux 27.5 use?
- A: The dw-link Flux 27.5 comes with a 7.25in X 1.75in air shock. Its shock uses the 21.8mm wide reducers with 6mm x 40mm hardware. For more information regarding the Fox shock visit www.foxracingshox.com/fox_tech_center/ .
2013 models come equiped with Fox CTD shock.
tech note: Our shocks come custom tuned from Fox Shox for our bikes specifically, which has a very low- compression and low- rebound setting. This is crucial for the dw-link to perform to its fullest.
Q: Which Shock will fit on my Flux 27.5?
- A: The Flux 27.5 uses a 7.25" X 1.75" on all versions 2013 + [184mm X 45mm ].
• The Fox RP23 WILL fit. : as of January 1, 2010.
Note: If you find that any of the above information is not current or if another shock brand does or doesn't fit, please let us know so we can update our informtion. Go to our Contact Us page..
Q: Will the SRAM XX Gruppo fit on my Turner?
- A: Yes, but it is VERY Important to order the correct one.
• The 28/42 chainring combination,
• with a GXP bottom bracket,
• as well as a Wide Q-Factor (the Narrow Q-Factor will NOT fit)
• and a 34.9 High-Mount Top-Pull Derailleur are necessary for proper fitment.
Please be aware that if your use any other SRAM XX setup it may not fit correctly and damage the frame and/or components. If this is at all confusing please consult your local Turner Dealer and/or go to the SRAM XX website.
Q: Torque Wrench Specifications for my Turner are?
- A: These Torque Wrench Specifications apply to all dw-link Turners:
• Main Pivot- 10 ft-lbs / 13.7 nm / 121 in-lbs.
• DW Link- 6.6 ft lbs / 9 nm / 80 in-lbs.
• Shock Bolts- 6.6 ft lbs / 9 nm / 80 in-lbs.
• Clevis Bolts- 6.6 ft lbs / 9 nm / 80 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.
For more information on the dw-link go to: www.dw-link.com.
Q: Why use Journal Bearings?
- A: 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 ability.
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 adverse and often 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: Taco to a burrito to nothing: What happened to the Mexican food?
- A: 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 a unique shape that accomplishes this goal. So in an effort to lighten and stiffen the Turner Flux 27.5 we found a better solution then relying on mexican food.
