Q: Where are Turner's made?
- A: The frame ideas and designs come from a world none of us can really understand, no not another planet, but David Turners mind.
All of the design works is done in Murrieta, CA; in a tiny office with insufficient air conditioning in the summer and not enough heat in the winter.Out of the same office we handle all of the marketing, sales, quality control and final assembly.
Every frame is loved with pride and joy until it has been delivered to its proud new owner.
As for the actual fabrication, our frames are built by a facility in Portland Oregon; and yes in their spare time they tinker with spacecraft and jet airplanes.
Q: Which size is correct for me?
- A: We give the best possible size range chart for the general rider for each one of our frames. Check out the sizing chart of the frame you are interested in to get an idea of the proper sizing. Our feeling is that the most important dimension is the top tube length.
Our recommendation would be, if you currently have a frame you are comfortable with, measure the top tube length of that frame, horizontally from the center of the head tube to the center of the seat tube (see this photo). Then compare that measurement to the top tube length of the frame you are looking to purchase. The idea is to get both measurements as close as possible to each other. If they are real close, but not exact, you can always make up for the difference by trying different stem lengths.
In general, if you are still undecided at this point, we recommend leaning toward the larger size of frame and using a shorter stem size to help make up for the measurement difference. A larger frame will be more stable than a smaller frame due to the longer wheelbase.
Remember, these are strictly recommendations to help you decide which frame size to choose. Please see your local dealer for a proper fitting if necessary. .
Q: What maintenance is required on my pivot bearings?
- A: Our pivots are specially designed to give you many hours of trouble free usage with easy maintenance. Each pivot is fitted with a custom made seal to help prevent contamination inside the bushing and pivot shaft surface.
Second we have a grease port on all five of our pivots allowing you to grease each one without disassembling them. We recommend that pivots be lubed via the zerk fittings every 15-20 hours of saddle time, in wetter conditions lube more frequently.
The pivot system is a sealed system, if you cannot add anymore grease then the pivot is full and will no longer accept lubricant. Please see our dealers or online store for our custom grease gun and M-Prep lube.
Q: Do Turner frames have a replaceable derailleur hanger?
- A: Yes, every Turner frame has a replaceable derailleur hanger. They are available through your local dealer or through our Online Store. Please make sure you purchase the correct hanger for your application. We recommend having a spare as they can help avoid a long walk home!
Q: What Front Derailleur does my Turner require?
- 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 size seatpost does my dw-link Turner take?
- A: All dw-link Turner's take a 30.9mm seatpost.
Pre-2009 Turners, horst-link or TNT, use a 27.2mm seatpost.
Q: Can I use a quick release seat collar and what size do I get?
- A: Yes, you can use a quick release seat collar on all dw-link Turner's. The seat collar size from the factory is 35mm.
Pre-2009 Turners, horst-link or TNT, use a 31.8mm seat collar.
Q: How much seatpost insertion do I really need?
- A: Turner recommends a minimum of 4 inchs or 100mm of post insertion into the frame.
Q: Why does Turner use bushings (Journal Bearings) ?
- A: The journal bearing design offers incredible strength and long life with very little maintenance. Bearings are designed with high-speed rotation in mind (skateboard wheels, drill motors etc.) The journal bearing we use has a purpose of holding a very tight tolerance along with carrying a load much greater than that produced by a bicycle frame, these two attributes we feel are essential to a great riding bike. The rear of our frames often gets praise for how stiff it is laterally and how well it tracks through the roots, ruts, and rocks encountered on a mountain bike.
Because a bearing found in a bike pivot never makes a full rotation, you rely on two maybe three of the balls in the cartridge to carry the entire load and pressures generated by the rider. Over time this is what creates that "crunchy" feel or "squeaky" sounds people often comment about.
Bearings are also made of steel, steel rusts after being exposed to water, grit and grime, again found in our everyday riding. So long lasting, tight tolerance and incredible load bearing capabilities are why we have chosen to stick with journal bearings.
Q: How should I setup the rear air shock sag?
- A: Start with body weight in the main air chamber. Get on the bike with all your riding gear, including water in the Camelbak, now check suspension sag. To do this, pull the little O-ring up on the shock shaft; now get off the bike gingerly as to not upset that measurement. Once off the bike, measure how much shock shaft is exposed above the O-ring. For proper setup you should measure about 30% of sag from total stroke.For more shock setup help go to our tech page.
Q: What if I run a fork with more travel than specified?
- A: By running a longer than recommended fork, it will slacken the angles, rasie the bottom bracket and increase the standover. A general rule of thumb is for every inch of travel change equates to a degree of angle change.
Q: Will you sponsor me?
- A: Maybe. Turner Suspension Bicycles is proud to sponsor talented riders across several disciplines of mountain bike racing. For more info contact us here.
