You mean my LTKs, or from RDS? I'm holding onto mine for now...never really have installed them yet since snagging them from Brad (another list member).

Oh, the long travel kits were made by Rapid Descent Scotland? Damn, there's a whole lineup of stuff that's going away now, isn't there?

Just back from a shakedown ride and uncovered a few easily fixable things, I need a long higher stem and maybe some riser bars to slow the steering down a bit. Also discovered that access to the Risse shocks with the pump is pretty hard, but the good part is the shocks came directly from Risse and were so close to perfect I only fiddled with the pressures for testing.

The ride uncovered no problems with the LTK and Risse combination. However the trail I rode only used about 1/3 of the available travel. I will need to ride it some more to allow the shocks to break in and then we'll see how much travel I can actually get out of the LTK/Risse combination. That said, I have to say I love being back on an 855.

I have an 845 with an extra rear shock (in above average condition) and an excellent Vector II fork in case anyone might be interested.

Got any pics of your 845? And what is the top tube length?

Actually it is really an 854 not and 845 (that would be really old) and currently I do not have any pictures, but if rain stops later I will shoot some for you and take all the measurements.

Terry, I was able to sneak out between rain showers and get a few pictures of the 854. Also the TT is 21.75 inches.

Here are the photos and I will be happy to take some of any particular areas of interest you wish.





As I mentioned I have extra rear shock with good elastomers and a Vector 2 fork that I would be willing to sell as well.

Yeah, that's one reason I do not ride it very much. The same thing with my 855, it's a medium and I really need a L to be completely comfortable.

Got a question for the engineer types here, has anyone tried swapping the fork leg on the Grivin fork from side to side and if so what happens to the handling of the bike and the fork travel?

Curious since my 855 is a touch small for me and wondering if that might slow the steering a bit.

That would be me, and yes it did dampen the twitchyness. What I found is that it increased the rake and lengthened the wheelbase. Kept it that way until I blew the noleen shock, then went with a MegaAir.

Give it a try.

Terry comes through with the details once again...but before the work of reversing the legs, have you tried adjusting the rake using the top leg mount "axle"? It has eccentric ends, and turning the "axle" via the hole with a nail or something adjusts the rake. You'll need to loosen the M6 bolts on each end first, and when tightening them back up use the same nail in the hole to retain the selected adjustment.

If you've already done this, though, and it's still too fast then you could try reversing the legs.

Another option would be a longer stem...the more the control surfaces are forward of the fork the less squirrely the steering will be...of course you can only do that so much before you're splayed out like Thanksgiving turkey (like those old 150mm stems...what were they thinking??).

Thank you gentlemen for the input.

DugB, I have one of those 150mm Specialized stems in Ti that I use on an AMP Research B4 since the bike is too small...it is quite humorous indeed.

I was planning on putting on a longer taller stem before anything like switching the fork legs. Thanks shovelon for the input as well.
