Thanks to the very progressive leverage ratio, a coil shock would fit the kinematics. But for the intended usage of the ONE-TWENTY and NINETY-SIX LITE, we recommend using air shocks due to the lower weight and easier adjustment.
Yes, a shock with a piggyback can be mounted. Especially during very long descends, the piggyback helps to keep the suspension performance consistent. If upgrading to a piggyback shock, we recommend the Rock Shox Super Deulxe with the following tune: 190X45 0L1 PRL 320 HBO
We recommend forks with travel between 110 mm and 130 mm as we see that the 130 mm fork is ideal for the intended use as an allround bike and the 110 mm fork for a modern XC- and marathon course.
Yes, category 4 means that enduro riding and racing are allowed and approved.
Even though the MERIDA development team is a big fan of mullet bikes (as seen on the ONE-SIXTY/FORTY and the eONE-SIXTY), we have chosen 29" wheels across all sizes due to the better rollover performance.
Fitting a 27.5" rear wheel into the frame would be possible, but this would impact the geometry: The head tube angle and seat tube angle would be much slacker, and the bottom bracket would be critically low.
That's why we do not recommend compromising the balanced 29" geometry with a Mullet wheel, especially because the ONE-TWENTY is already very agile and playful.
No, there is no adapter required. On the seat tube, a 0.5l bottle can be mounted at all sizes, and on the down tube, it depends on the frame sizes. A 0.5l bottle can be mounted in XSHORT, 0.68l bottle in SHORT and MID and 0.75l bottle in LONG and XLONG. If only one bottle is mounted, all frame sizes can accommodate a 0.75l bottle.
The adjustable TEAM TR seat post is not specified, as the focus of the new ONE-TWENTY was on simplicity and affordability. But we ensured that even the shorter sizes could benefit from long travel dropper posts. XSHORT and SHORT will have 150 mm travel, MID 170 mm and LONG and XLONG even 200 mm.
In general, we wanted more progression to work well with newer rear shocks with bigger air chambers. Increasing the shock progression to 14% (from sag to 95%) means we give greater support at the end of the travel and increased control in demanding situations. With less suspension travel compared to enduro bikes, the ONE-TWENTY’s more progressive leverage curve (compared to the ONE-FORTY) helps to absorb hard impacts even with less travel.
The anti-squat graph describes the suspension behaviour during pedalling. We wanted a reasonable amount of anti-squat at the start and middle part of the travel, to provide highly efficient pedalling performance. However, the anti-squat value becomes much less when you are deep into the travel, where pedalling efficiency is of little concern. The end result is a suspension kinematic that pedals well with very little pedal bob, but is active and unhindered on descents and big hits.
The influence of the braking on the suspension is described by the anti-rise figures. Compared to the previous ONE-TWENTY, we have reduced the anti-rise to make the suspension more active under braking. At sag, the anti-rise is a little less than 100%, which helps to keep the bike level under braking, whether on steep or smooth fast trails. But deep in the travel, the anti-rise decreases, leading to unhindered suspension performance for increased grip while slowing down on rough terrain or after big drops.
