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: Does Turner offer complete bikes?
A: NO, we feel you are spending your hard earned money and you should be the one to choose what you get,
not some product manager who is overworked and lucky to see the light of day much less actually get out and ride.
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 to keep my pivots running nice and smooth?
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 $20 each and 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 Turner's, except the Nitrous, use a 34.9 top pull down-swing "traditional" front derailleur. The Nitrous uses a 31.8mm down-swing. A good example to this type of derailleur is the Shimano M971.
Q: What size seatpost does my bike take?
A: All Turner's take a 27.2mm seatpost.
Q: Can I use a quick release seat collar on my Turner frame and what size do I get?
A: Yes, you can use a quick release seat collar on all Turner's. The seat collar size from the factory is 31.8mm but a Salsa 32mm collar will work as well.
Q: I'm a really tall guy with a short seatpost, how much seatpost insertion do I need?
A: Turner recommends a minimum of 4 inchs or 100mm of post insertion into the frame.
Q: Why does Turner use bushings (Journal Bearing) instead of the hyped up bearings that other bike brands use?
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: I weigh about 160lbs, 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.
Q: You specify certain travel forks for each model, what if I run a fork with more travel or a longer axle to crown measurement?
A:By running a longer than recommended fork, it will slacken the angles and increase the standover. A general rule of thumb is for every inch of travel change equates to a degree of angle change.
Q: How do I route my cables?
A: Look Here.
Q: Can I have a catalog?
A: Yes, you can be tree friendly and download our catalog here.
Q: Will you sponsor me?
A: Maybe. 
is a good place to start.
Q: Can I have free stickers?
A: Yes, just send a Self Addressed Stamped Envelope to:

And we will be happy to send a few stickers your direction.
Q: What if I need replacement parts?
A: Please contact your local dealer Dealer Listings or go to our Online Store.
Rocker Questions
Back to the top
Q: I see many people upgrading their rockers (rocker plates are what actuate the shock and attach the seastay to the frame) what and why are they doing it?
A: Many Turners have parts based on the same platforms and part dimensions.
Many Turner owners want to upgrade their older frame to current day standards.
This makes the frame a viable candidate for parts upgrades as the market changes its prospective direction.
This does not mean that a ten year old Burner can run newer RFX rockers, what it does mean
is the ability to upgrade your current bike to the next new model year if so desired and available.
Q: Is my Turner frame viable for a rocker swap?
A: Many older Turner frames have no upgradeablity, only in the last few years have owners been able to change rockers to alter their frame from stock.
Look up your frame in the FAQ for more information.
Horst Link? TNT?
Back to the top
Q: What happened to the Horst Link?
A: After extensive computer modeling and real world testing, David Turner found the axle path was virtually unchanged. Based on this information Turner switched to TNT.
Q: What is the difference in axle path with the current TNT rear?
A: With animated modeling used, it was deduced that the axle path on a 5-Spot only changed by 1mm at the very top of the stroke, or bottom out.
Q: Will I notice a change in the ride?
A: Most riders who did a back to back comparison could not distinguish any differences in ride characteristics. Most comments from testers was "it rides like a Turner." See for yourself!

Q: I hear about rocker swaps for older 5-Spots, what can I run?
A: The 5-Spot has gone through minor changes over the last four years. The 2003-04 5-Spot came with a Romic coil shock and a 5.1" rocker. This rocker has a measurement of 215mm from center of shock bolt hole to center of rear bolt hole.
The 05-06 5-Spot came with a Fox Rp23 and or Dhx Air shock with a 5.3" rocker measuring 223mm . The new 5 1/2 Spot runs a 5.5" rocker with a measurement of 230mm. Newer rockers can be run on older 5-Spots. The 5.3" rockers fits every year of Spot. The newer 5.5 rockers will require the
user to make sure they don't run any chainring smaller than a 44 tooth or lower the front derailleur due to a bash guard. You will also want to check your frame for front derailleur cable stop clearance. 03-04 Spots had the front derailleur cable stop welded to the back of the seattube; the 05 and newer have the cable stop attached to the side of the seattube.
This allows for proper tire clearance under full compression when running newer longer rockers and should be checked prior to riding.
