    Anyone on this link have pictures of the Montesa Cota 4TR 260 shock (Ollie 16v ) on the bike, off the bike, and have the eye to eye length with eye width on each end? I'm unable to get hold of Martin.

    To start with. Thank you for your time. I pulled the shock. 10 1/4 center to center . I have ordered a TRP replacement but will gladly send E7AE4570-B8F2-466C-9AB2-95D3B5F3318F.jpeg 48FFD027-2C5C-469B-804A-CC49F38B825B.jpeg 300DAE4C-A8A4-4FA6-8CAC-FF7CA5D5EB21.jpeg CCB35A1A-3EAD-46D2-ABC5-A754BEEACBC8.jpeg you this to you to experiment on. Kind of interested in the remote reservoir idea and will be happy to switch back for testing. No hurry as I will have a shock for the bike. I can pull the spring and get the pressure measurement if you like. If your busy with other projects thats fine to Thanks again for your knowledge and input

    Take measurement width of the eyes, take photos of the back of where the shock sits farther back so I can see location for a reservoir.

    I'm going to need an exact measurement on the shock eye in mm, use a Vernier Caliper. Give me your # again and I'll call.

    That's what I thought, should have between 60 to 70 Lbs. Most people think they need a stiffer spring when all they need is a shock with the correct pressure inside. For this shock around 210 to 220 P.S.I.
