TTX22m Springs
Original TTX22m was released with spring series of different length, rate and weight - weight for the springs themselves. Available series have evolved over the years, with new lighter series (currently 18077, 18073, 18075) replacing previous series (18070 and 18060) with other series released in-between. When this page is being updated (2023) original TTX22m rear shocks are compatible with the majority of current spring series (18077, 18073, 18075) but in some cases you will need previous series (18076 for shocks under 50mm travel, 18065 for 10.5" shocks) that are still available but may require a bit of research. Regarding 10.5" shocks, Cane Creek springs of the right length (for 3.5" travel) are compatible.

TTX22m Mounting Hardware
TTX22m can use the majority of mounting hardware (3P, 5P, 7P, IGUS, DU..) but many units have been produced with 16mm eyelets that require 14mm hardware (which are now considered legacy) OR with 16mm eyelets with a reducer to 15mm fitted from factory in order to use 12.7mm hardware.
| Eyelet | Internal diameter |
Important |
| Original eyelets and all eyelets on original cylinder heads (non-Trunnion) | 16mm | Require 16 to 15mm reducers to use common 15mm hardware. Later units were fitted with a reducer from factory. |
| Eyelets on metric and Trunnion shocks | 15mm |
