Any issues with the seals on the coil shock? I have a Mach 5.5 and a Phoenix DH bike. I would like to try a Fox DHX2 on it but Pivot seems against coils on their DW Links

Here is what Pivot has to say about it,

Although the Firebird 29 features a rising rate design that functions with coil-over shocks, the clevis design adds additional leverage to the shock shaft and internal piston bushing that can result in premature wear of the shock or in the case of some shock brands, a total failure of the shock shaft so we do not recommend running a coil-over. For maximum performance and durability, we recommend staying with the Pivot spec’d FOX Float X2 shock (or DPX2 on our race builds). The FOX Float X2 air shock, Rock Shox Super Delux or Vivid Air and most any other DH based air shock design features a tunable spring curve for better overall performance with the Firebird 29’s linkage design. The Pivot Factory Racing DH World Cup team has the option of running either the FOX X2 air or coil and each member of the Pivot Factory Racing team has found the air shock to offer better performance and control and ultimately faster times on the race course. If you absolutely insist on running a coil-over shock on your Firebird 29, then either run the FOX X2 and be prepared to service the shock at short intervals to prevent failure and potential damage to the frame or the PUSH industries ElevenSIX shock which features an oversize shock shaft and bushing, as well as a captured spring at both ends of the shock. If you choose to run this shock, it is the user’s responsibility to follow the tune guidelines that PUSH provides and also service the shock at much shorter intervals. Any frame damage occurring due to shock failure from using any shock other than the Pivot supplied FOX Float X2 or DPX2 will not be covered under warranty.

The clevis is really short on this bike.
There are also other coil shocks with larger shafts like DVO and Rock Shox that would probably work. Of all the shocks out there the Cane Creek pictured is probably my last choice as far as the shaft and seal head bushing goes. The Double Barrel does have great damping and a cushy bottom out bumper though.

Des problèmes avec les joints sur le choc de la bobine? J'ai un Mach 5.5 et un vélo Phoenix DH. Je voudrais essayer un Fox DHX2 mais Pivot semble contre les bobines sur leurs DW Links

Bouba, vire moi le sticker orange sur l'étoile du disque stp hahaha

Au passage ton dérailleur c'est plus un XT qu'un SLX non ?

Sinon on va quand dans les ardennes rouler avec ta bicyclette ?

Ça fait plaisir à lire. Je me demandais qui verrai ces deux points. J'ai eu pour la fourche mais rien pour le reste. Merci Nico :-)

Ps: pour les Ardennes il va falloir que je me fasse une santé. Un grand avec des cheveux me disait que tu étais bien. Affûté ;-)
