Determine Which 2021-2024 Transfer Seatpost Will Fit Your Bike
Follow the steps below to determine which FOX Transfer Seatpost will work best for you and your bike frame. This guide can be a helpful tool for selecting the appropriate model of FOX Transfer Seatpost before purchase. You will need your frame and original rigid seatpost to make this determination.
Complete User Specification Drawings for the FOX Transfer Seatpost that contain additional information are shown at the bottom of this page.

Step 1
With your original seatpost set to your desired ride height, measure from the top of the seat collar to the center of the saddle rails. This will be Measurement "A".
Compare measurement "A" to the charts below to determine the maximum travel Transfer Seatpost that will work for your application.
| Measurement A | Transfer Travel (Internal Routing) |
| 238.9mm-380.7mm | 200mm |
| 213.2mm-375.1mm | 175mm |
| 188.2mm-318.2mm | 150mm |
| 163.3mm-263.5mm | 125mm |
| 138.3mm-208.6mm | 100mm |
If your measurement "A" does not fall within any of the tables in step 1 above, please contact FOX.
If your measurement "A" falls within the tables in step 1 above, continue below to check for proper insertion clearance within the frames seat tube.
Step 2
You will also need to check that the FOX Transfer Seatpost will fit deep enough into your frame without contacting any internal part within the frame.
Carefully insert your original seatpost fully into the frame until it contacts any obstruction. This could be a suspension pivot or a bend in the seat tube. Measure from the top of the seat collar to the center of the saddle rails again. This will be Measurement "B".
Step 3
Remove the original seatpost and measure from the bottom of the post to the center of the saddle rails. This will be measurement "C".
Subtract measurement "B" from measurement "C" to determine measurement "D".
Step 4
Add measurement "A" to measurement "D".
Compare "A" + "D" to the charts below to verify that at your desired saddle height, the FOX Transfer will be able to insert deep enough into your frame without contacting any internal part within the frame.
Your "A" + "D" value must be equal to or greater than the number in the table below for that specific post to work with your frame.
| Measurement A + D |
Transfer Travel (Internal Routing) |
| 560mm+ | 200mm |
| 505mm+ | 175mm |
| 448mm+ | 150mm |
| 393mm+ | 125mm |
| 338mm+ | 100mm |
If your measurement "A"+"D" does not fall within any of the tables in step 4 above, please contact FOX.

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. In the USA and Canada, you can request a Return Authorization number directly at this link: https://www.ridefox.com/rarequest.php?m=bike. For riders in other countries, you can find your regional service center here: https://www.ridefox.com/contact.php?c=worldwide&type=bike&country= |

| 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. |
