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 SL 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 SL 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 SL 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 SL 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 SL 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 SL seatpost may be carefully clamped in a workstand. 

WARNING: The maximum torque for the Transfer SL seatpost collar binder bolt is 5.1 N•m (45 In-lb). Actual required torque will depend on rider weight, bike frame, and type/brand of seatpost/seat collar. Correct torque will support the rider and not interfere with seatpost function. If the torque is too high, the seatpost may not return fully from all positions or may not move up and down properly. If the torque is too low, the seatpost may not support the weight of the rider or may not remain stationary at the seat tube. Failure to use the proper torque for your seatpost/seat collar combination can result in loss of control, resulting in SERIOUS INJURY OR DEATH.

Internal Cable Routing

STANDARD INTERNAL CABLE ROUTING:

This procedure covers most seatpost and remote lever combinations, which begin with installing the cable at the seatpost end. Contact your dealer to help you understand which instructions apply to your specific product combinations.

  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. Make sure to allow enough slack for proper steering clearance.
  2. Install a ferrule on the seatpost end of the cable housing. Install a ferrule onto the cable housing at the remote lever end.
  3. Install the end cap into the bottom of the seatpost until the o-ring seats into the groove inside the seatpost. The end cap should be flush with the end of the seatpost.

  4. Starting from the seatpost end, lightly lubricate the cable and install it through the cutout in the side of the seatpost and into the cable hanger.
  5. Check that the cable head is centered in the cable hanger. Route the cable beneath the cable clamp bolt and tighten to 2.8 N•m (25 in-lb).
    transfer-sl-window-with-cable.jpg
  6. Route the cable through the end cap and into the cable housing.
  7. Insert the seatpost into the seat tube while pulling the cable from the remote lever (use friction paste for carbon frames if needed). Install the seatpost 20 mm (.79 in) into the frame and temporarily tighten the seatpost collar binder bolt just enough to hold the post in place. WARNING: The Transfer SL seatposts are directional and proper orientation can be identified by laser etching “Rear of Post.”
  8. Install the cable into the barrel adjuster of the lever until it exits past the clamp bolt. Ensure the barrel adjuster is turned to the middle of its range. Pull the cable tight to seat each end of the housing.
  9. Hold the lever in the fully extended position while tightening the clamp bolt to the correct torque value shown for your lever (see image 3). Make sure there is a small amount of cable slack and some “free play” at the lever when the seatpost is in all positions.
  10. Press the lever down completely 5-10 times. Use the barrel adjuster to fine-tune the cable tension. If there is too much cable slack, loosen the lever clamp bolt, pull the cable, and reclamp the bolt to the proper torque.

  11. Check that the seatpost properly moves into all positions.
  12. Set the seatpost to the desired height and tighten the seat collar binder bolt to a maximum of 5.1 N•m (45 In-lb). Check again that the seatpost properly moves into all positions. WARNING: The maximum torque for the Transfer SL seatpost collar binder bolt is 5.1 N•m (45 In-lb). Actual required torque will depend on rider weight, bike frame, and type/brand of seatpost/seat collar. Correct torque will support the rider and not interfere with seatpost function. If the torque is too high, the seatpost may not return fully from all positions or may not move up and down properly. If the torque is too low, the seatpost may not support the weight of the rider or may not remain stationary at the seat tube. Failure to use the proper torque for your seatpost/seat collar combination can result in loss of control, resulting in SERIOUS INJURY OR DEATH.
  13. Make sure to leave approximately 0.8 in (20 mm) of cable length visible at the remote end. Cut the cable to the correct length and install the end crimp. Tuck the end of the cable into the recess in the underside of the lever (not applicable for drop-bar lever).

 

INTERNAL CABLE ROUTING FOR COMPATIBLE LEVERS:

This procedure is intended to supplement the manufacturer’s instructions for compatible remote levers, such as Shimano GRX, which begin with installing the cable at the remote end. Contact your dealer to help you understand which instructions apply to your specific product combinations.

  1. Install the remote lever, cable housing, and cable according to your remote lever manufacturer’s instructions. Make sure to install a ferrule to the seatpost end of the cable housing.
  2. Make sure to leave 25-30 mm (0.9-1.2 in) of cable length past the end cap.
    window-with-cable-and-length-callout.jpg
    Install the end cap into the bottom of the post until the o-ring seats into the groove inside the seatpost. The end cap should be flush with the end of the seatpost.
  3. Install the seatpost 20 mm (.79 in) into the frame and temporarily tighten the seatpost collar binder bolt just enough to hold the post in place.
  4. Use pliers to access the cable through the cutout in the side of the seatpost. Route the cable beneath the post cable clamp bolt and use the pliers to pull any remaining slack in the cable. Tighten the post cable clamp bolt to 2.8 N•m (25 in-lb), making sure there is a small amount of cable slack and some “free play” at the lever when the seatpost is in all positions.
  5. Press the lever down completely 5-10 times. Use the barrel adjuster to fine-tune the cable tension. If there is too much cable slack, loosen the post clamp bolt, pull the cable, and reclamp to the proper torque.
  6. Check that the seatpost properly moves into all positions.
  7. Set the seatpost to the desired height and tighten the seat collar binder bolt to a maximum of 5.1 N•m (45 In-lb). Check again that the seatpost properly moves into all positions. WARNING: The maximum torque for the Transfer SL seatpost collar binder bolt is 5.1 N•m (45 In-lb). If the torque is too high, the seatpost may not return fully from all positions or may not move up and down properly. If the torque is too low, the seatpost may not support the weight of the rider or may not remain stationary at the seat tube. Failure to use the proper torque for your seatpost/seat collar combination may result in problems with the height of the seatpost, which can result in loss of control, resulting in SERIOUS INJURY OR DEATH.

 

SADDLE INSTALLATION:

  1. Place the lower saddle clamp on the seatpost with the correct side positioned toward the rear of the bike.
    post-head-with-torques.jpg
  2. 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 rear of the bike.
  3. Place the two barrel nuts into the upper clamp. Install the two saddle clamp bolts and two washers into the underside of the upper post, through the slots of the upper clamp, and through the barrel nuts.
  4. Adjust the level and fore/aft position of the saddle. Then use a 4 mm hex wrench to tighten the saddle clamp bolts to 45 in-lb (5.1 N•m).


WARNING: Use the Transfer SL 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 SL Seatpost

Understand the basics before using your Transfer SL seatpost:

  • The Transfer SL seatpost has two positions for saddle height. Press and hold the lever as you change the position.

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

  • Once the seatpost is in one of the two positions, release the remote lever. Always release the remote lever first before releasing the pressure on the saddle with your body.

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

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?
