WARNING: FOX products should be installed by a qualified bicycle service technician, in accordance with FOX installation specifications. If you have any doubts as to whether or not you can properly install the Transfer adjustable height seatpost on your bicycle, defer to a professionally trained bicycle service technician. Improperly installed products can fail, causing the rider to lose control, resulting in SERIOUS INJURY OR DEATH.

WARNING: Regardless of bicycle frame tube configuration, the best structural support is achieved when the Transfer seatpost is inserted at least to 1) the minimum insertion mark on the seatpost, AND 2) the minimum insertion point specified by the manufacturer of your bicycle frame. Neglecting these two items risks causing damage to the frame and seatpost, resulting in SERIOUS INJURY OR DEATH.

WARNING: Make sure that the Transfer remote lever does not interfere with normal brake and shift lever operation. Failure to do so can result in loss of control, resulting in SERIOUS INJURY OR DEATH.

WARNING: Make sure that the bottom cap of the Transfer seatpost never touches any part of the frame, or the rear shock through the entire range of shock travel. Make sure that no part of the internal actuation mechanism at the base of the seatpost contacts any internal seat tube parts such as frame pivots or bottom bracket parts. Failure to do this risks causing damage to the frame and seatpost, resulting in SERIOUS INJURY OR DEATH.

WARNING: Make sure your seatpost is the correct outer diameter to fit your bicycle seat tube inner diameter. Using the incorrect size of the Transfer seatpost on your bicycle can lead to product damage, personal injury, or both.

WARNING: Make sure the cable housing does not interfere with the swingarm linkage, rear tire, clothing and riding gear, and steering clearance. Never attach the cable housing to any part of your rear shock.

WARNING: The anodized surface of the upper seatpost, like a rear shock body, serves as a sealing surface. Always take every precaution to avoid causing abrasion damage to the anodized surface of the upper seatpost. The upper portion of the Transfer seatpost may be carefully clamped in a workstand. Do not clamp the cable pulley mechanism of collar cable routed Transfer seatposts.

Remote Installation

Internal Cable Routing

 

  1. Route the cable housing from the remote lever into the internal routing port of the frame. Push the housing through the frame until the housing emerges from the seat tube and extends approximately 2 in (50 mm) beyond the seat collar. Install a ferrule on the seatpost end of the cable housing.

  2. Install the cable bushing onto the cable. Seat the cable head into the counterbore of the cable bushing. Install the cable into the cable housing starting from the seatpost end.

  3. Seat the cable bushing into the actuation cradle at the bottom of the seatpost. Pull the cable at the lever end while pushing the cable housing into the frame to seat the housing against the cable stop at the base of the seatpost (see image below).

  4. Insert the seatpost into the seat tube while pulling the cable from the internal routing port of the frame. Tighten the seat collar binder bolt to set the seatpost to the desired height.

  5. Determine how much cable housing is needed between the lever and the internal routing port of the frame. Make sure to allow enough slack for proper steering clearance. Mark the housing where you intend to cut, but do not cut it yet.

  6. Remove the seatpost and cable from the seat tube, leaving approximately 2 in (50 mm) of housing beyond the seat collar. Remove the cable bushing from the actuation cradle. Remove the cable from the cable housing.

  7. Cut the cable housing at the mark. Install a ferrule onto the cable housing at the lever end. Lightly lubricate the cable and install it into the cable housing starting from the seatpost end.

  8. Seat the cable bushing into the actuation cradle at the bottom of the seatpost. Pull the cable at the lever end while pushing the cable housing into the frame to seat the housing against the cable stop at the base of the seatpost.

  9. Insert the seatpost into the seat tube while pulling the cable from the internal routing port of the frame (use friction paste for carbon frames if needed). Set the seatpost at the desired height. Tighten the seat tube collar binder bolt to the torque range engraved on the lower post. NOTE: Excessive bolt tightness can adversely affect the action of the seatpost.

  10. Install the cable into the barrel adjuster of the lever until it exits past the clamp bolt. Ensure the barrel adjuster is turned completely clockwise. Pull the cable tight to seat each end of the housing. Hold the lever in the fully extended position while tightening the clamp bolt to the correct torque value shown for your lever (see image below).

  11. Press the lever down completely 5-10 times. To remove any cable slack, loosen the pinch bolt and pull the cable, then hold the lever in the fully extended position while tightening the pinch bolt to the correct torque value shown for your lever (see image below). Use the barrel adjuster to finetune the cable tension.

  12. Cut the cable to the correct length. Make sure to leave approximately 0.8 in (20 mm) visible at the remote end. Install the end crimp and tuck the end of the cable into the recess in the underside of the lever.

  13. Install the two saddle clamp bolts and two barrel nuts into the upper post (see image below).

  14. Place the lower saddle clamp on the seatpost with the correct side positioned toward the front of the bike (see image below). NOTE: The FOX Transfer Seatpost can be used with saddles that have 7 mm round or 7 mm x 9 mm round or elliptical carbon rails. Use only the saddle rail sizing that is specified on the upper clamp. The FOX Transfer Seatpost cannot be used with saddles that have 8 mm round rails.

  15. Install the saddle on top of the lower clamp. Place the upper saddle clamp on top of the saddle rails with the correct side positioned toward the front of the bike (see image 13). Install the two saddle clamp bolts by hand into the slots of the upper clamp.

  16. Adjust the level and fore/aft position of the saddle. Then use a 4 mm hex wrench to alternate between the two saddle clamp bolts as you tighten them to 45 in-lb (5.1 Nm). NOTE: Access the bolt heads underneath the seatpost (see image below).

WARNING: Use the Transfer seatpost in a safe, controlled environment BEFORE using it during rides in order to fully understand how the seatpost functions. A sudden, unexpected impact from the saddle could cause you to lose control of your bicycle, resulting in SERIOUS INJURY OR DEATH.

Using the Transfer Seatpost

Understand the basics before using your Transfer seatpost:

  • Press and hold the lever to change saddle heights. Release the lever when the post reaches the desired height.

  • Use your body to press the saddle down as you change to lower saddle height settings and to guide your saddle as it returns to higher settings.

  • When changing seatpost height, always release the remote lever first before releasing control of the saddle with your body.

  • Practice within your abilities to gain expertise in using the Transfer seatpost before using it in more technical riding situations.



Service Intervals

To best maintain the performance and durability of your product under normal use, FOX recommends that you have regular Transfer Seatpost maintenance performed according to the service intervals listed below.

 

Recommended Minimum Transfer Maintenance Every Ride Regularly Every 125 Hours/Yearly, or whichever comes first.*
Clean exterior with mild soap and water only, then wipe dry with a soft towel. X    
Inspect your product for visual damage and function of all controls.   X  
Full Transfer Seatpost service (Full rebuild)     X

 

 

*For those who ride lift-accessed DH, Park, or Extreme Freeride or in extremely wet/muddy or dry/dusty environmental conditions where trail debris is sprayed onto the fork or shock while on the trail, FOX encourages riders to perform maintenance earlier than recommended above as needed. If you hear, see, or feel something unusual, stop riding immediately and contact a FOX Authorized Service Center for proper servicing.



Troubleshooting Guide

Symptom Possible Cause Check, in this order: If yes, then adjust this:
Creeps down when sitting on the post Too much cable tension Is there any freeplay in the lever (a.k.a. slack in the cable)? Turn lever barrel adjuster to the point where the tip of the lever can freely move 2-5mm
  Is something preventing your lever from returning freely or completely? Check lever function, visually ensure no damage, fix/replace as needed.
Is your cable too short, or catching on something?  Does the post only creep with the bars turned? Fix/replace inner cable and housing as necessary
Is the cable pinched in the frame?  If so- especially if the saddle height has been raised- the cable could be partially pulled.   Loosen the seat post clamp, lower the post in the frame ~10mm, re-clamp - is it still a problem?
Is the cable kinked or sharply bent in the frame?  Does the post creep when removed from the bike? Fix/replace inner cable and housing as necessary.  Make sure you do not force the post into the frame as this can bend the cable (especially if there is a bend or other interruption inside the frame)
Slow to extend through entire stroke Not enough cable tension (cable isn't being fully pulled) Is the seatpost clamp gap aligned with the slot in the seattube?  Rotate clamp so that gap is 180 degrees from slot in seattube.
  Does this only happen in cold temps, or after the post has been stored in the down position?  A slower return is to be expected in cold temps.  Cycling the post up and down by hand several times can help warm things up.
Is there too much freeplay in the lever (a.k.a. slack in the cable)? Turn lever barrel adjuster to the point where the tip of the lever can freely move 2-5mm
Is there a broken barrel adjuster on your lever (causing too much slack in the cable)? Replace adjuster or lever as necessary
Is the seatpost clamp bolt too tight?  Loosen it completely and check again.  Does the post return better? Clean post and frame seat tube with alcohol, apply friction paste to inside of frame and bottom of post.  Tighten seatpost clamp to the minimum torque required to avoid the post slipping in the frame.  Increase to the point at which you can start to feel a tight spot when moving the post up and down, and then back off 0.5 N-m.  Do not torque above 5 N-m.
Is this fixed by re-lubricating the seal and bushings?   Try using a thin non-metallic zip tie (or similar) to lightly lift the wiper seal lip and add a drop of Float Fluid or similar oil. Do this at 2 places around the post, 180-deg opposite each other.  On MY2021 and newer, you can also do this by unthreading the post collar, lubricating the upper post with Slick Honey, Slickoleum, or a similar grease, and then tightening the collar to 12 ft-lb torque.
Is the cable kinked or sharply bent in the frame?  Is the post slow to return when removed from the bike? Fix/replace inner cable and housing as necessary.  Make sure you do not force the post into the frame as this can bend the cable (especially if there is a bend or other interruption inside the frame)
Check the post off the bike, with no cable attached, by pressing the lever on the bottom of the post with your thumb.  Does it still return slowly?  If not, re-check the items above. If you've checked the items above, and the post isn't working properly when removed from the bike, please contact your local FOX Service Center to arrange for diagnosis and repair.

Slow return at a only certain point in travel, or only at the end of the stroke, or you can feel a 'tight spot' when pushing the post down Binding due to too much torque on seatpost clamp Is the seatpost clamp gap aligned with the slot in the seattube?  Rotate clamp so that gap is 180 degrees from slot in seattube.
  Does this only happen in cold temps, or after the post has been stored in the down position?  A slower return is to be expected in cold temps.  Cycling the post up and down by hand several times can help warm things up.
Is the seatpost clamp bolt too tight?  Loosen it completely and check again.  Does the post return better?
