GasGas EC 300 2011 need new shock spring
Hi All
I am very happy i found this forum, been reading most of the suspension posts but still have some questions. I have a new GasGas EC 300 Racing 2011, i am from Israel so the racing model here comes with the Marzocchi 48 mm front and Ohlins 888 rear. my weight is 200 pound witout gear (so i assume 10-20 pounds more with gear) rear shock stock spring is 5.2, and here is the problem: with shock spring preload at 10mm from full open i get a static sag of 35mm and rider sag 135mm, so i had to close shock preload to 25mm from full open and now i get the desired 105mm rider sag but the static sag is only 20mm. all this tells me my rear shock spring rate is too soft, any idea what spring rate i need and where can i get it in the USA or Europe? Thanks for the help. (can add pictures if its any help) |

I weigh within 5 lbs of you and the 5.6 spring worked perfectly for me. The Sachs and Ohlins spring can be interchanged but the 5.6 Sachs aftermarket spring I bought happened to be slightly bigger ID so Les at LTR made me a spacer.

it may help someone..
after speaking with the main tech guy for Ohlins in Sweden, i need a 5.8 spring. he also noted that adding preload beyond the max 10mm can damage the shock internals. ordering a 5.8 shock from a dealer (those springs are hard to find as dealers hardly stock them) must say Stacy at Ohlins USA and Lars from Ohlins Sweden where super friendly and very happy to help. for now will set it back to 10mm preload and live with the sag i get, rather then push to 105mm with too much preload that can hurt the shock.

5.8 sounds too high. I'm 190 lbs and run a 5.4. I'd say you could go 5.6. I never heard of shock damage from too much preload, but it will make for a harsh action, especially on rebound from small impacts. You want to try to keep it under 10mm.

Why does height become a factor for a stiffer spring? I'm 6'6" tall so if there is a factor that makes a difference it should apply to me. |

i am not in a point to argue with your experience, i am having hard time deciding on which spring to go with, but 3 different Ohlins professionals Stacy from Ohlins USA, Lars from sweden and the Italian technician from Ohlins Italy that actually have that spring in stock say to go with the 5.8, and that in worst case i can always loosen preload to even 5mm to get the right sag and softer feel. they also said that if lars which is the top Ohlins technician say 5.8 than i should listen to him. so hard for me to argue. most of my riding is single tracks and special tests at fast speed, most of my rides are not relaxed with the boys but training for races or racing in worst case i just get a 5.6 later on. btw with the 5.6 what preload, static/rider sag you have now? thanks Last edited by drorsdd; 08-30-2011 at 03:05 PM. |

Yes, terrain and speed, while not the main factor, will have an influence as well. A fast sand rider will want it stiffer than a slower technical rider. Whats your terrain and ability?

riding level is i am not sure as we don't have classes like in the US , i am on the top division but in the medium to lower end so i would guess a B/C class rider. as it's pretty hot here most year long i always ride with 3 liter camelback (also in races) and tool pack , knee braces & leatt brace so i bet i am pushing 220-225 pounds with full gear.
