Title: lateral stiffness of the x57 compared to....?
Post by: scottmartin49 on November 25, 2009, 10:55:26 am
Been riding another single pivot lately and it seems pretty flexy. The only other fulls I've ridden were a 857 Proflex and a Turner DHR so not much to compare to. Any input? As this is pretty dependant on the physics developed, please include some info on your riding style and (ahem) "mass".

I thought the x57 was pretty good for xc trails -nothing too gnarly- and the Turner is a tank anyway, but I run about 100kg. I'm considering another bike, maybe a  4" Foes, but wonder if it's really worth it compared to the ol' 857.

Thanks in advance for your input!

I ride a 957, so the ride should be simalar. I have ridden a Foes Inferno, and it is solid as a rock. My 957 is quite fine for me, and I like a lilttle compliance in the ride. I have mounted a Manitou Swinger on the rear, with Simon's sealed bearing conversion, and the side to side flex is swallowed up by the the improvements in the rear travel. Both my 957 and Oz have swingers with Simon's sealed bearings, and I think the combo is unbeatable.

You can build up an 857 really lite if you are careful on components.

How did you attached the Manitou in the cone shaped end?
Do you have any pictures? I have a Swinger 3 for some months now, but haven't decided what to do...

Do you notice much difference in the sealed bearing conversion? I've always read about it in the forum, but still don't know if it makes a big difference or not...

Huge difference with bearing conversion. There is no longer drag on the pivots.

I welded plates to the strut. The shock eye drops right into the taper hole. As far as side to side movement, that is soaked up by the freedom of the new shock and efficiency of the sealed bearing pivot.

Every photo from Terry is like a picture post card. Nice!

That is possibly the best shock mount I have seen so far. I've been very happy with mine, but that is a lot simpler and neater. I think I will be copying that one in the near future.
