depends on the bike, shock, and clearance between the shock mount and the frame. I got one to try on my Turner and with the Fox CTD was not enough clearance to mount it. If it does fit, try it and see what it's like, should slack the HA and lower the BB. BUT FIRST..Watch for the rear tire hitting the seat tube or other clearances at full travel (i.e. let the air out of the shock/remove spring and cycle the rear susp. on the stand before you ride it)
only thing that I would be concerned with is where the links on the bike will be when sagged. especially on these newer multi link bikes, the location of the travel when sagged is most important to how the bike will pedal, how it handles bumps, etc... Just something to think about unless you're planning on using a single pivot bike.
Oh man. These things freak me out. If you knew how much work we put into tweaking the precise pivot locations in suspension geometry to make everything work as close to perfectly as possible, the thought of throwing your shock in somewhere totally random with a couple eccentrics of unknown offset is enough to make your head spin. I've been making those tweaks on a couple frames the last few years, all the while wondering where the threshold of diminishing returns is. These set it back about two years ago. I think I need to go lay down.
Here's some info from Vital. http://www.vitalmtb.com/forums/Downhill-Freeride,5/offset-shock-bushings-for-slacker-head-angle,5494
where do we get these bushings??...i found some but they looked like my 8 yr old kid made them in my garage with a hack saw and a dull drill bit.......
Sort of off topic, why is it that all the trick little gizmos are coming from other countries these days? Doesn't anyone in the USA manufacture anything anymore? I can't believe how many items I've bought from the UK in the last couple years that were under or around $100. Manufacturers in the states complain that nobody buys stuff made in the USA, but perhaps that's because so few in the USA make stuff people want.
Man, it's a mess. I've talked with a couple dozen capable machine shops over the last year, and all of them have the idea that "to compete with china" they have to make 100,000 part runs of anything they do and bang em out dirt cheap. Unfortunately, no one in cycling can afford to buy 100,000 of anything, much less sell that much of anything. Instead of finding a steady stream of infinite production runs, the shops are out of work and laying people off. They'd rather do that than take on short runs & wonder where the next one will come from, because banks haven't eased up on machinery loans to match the economic downturn, but become more active in calling the shots & if you don't have steady customers, you're done. Any of the MTB co's I've been working with have had to rely on interrupting production to utilize in-house machining (!$$$$$!) or get their short-run work done overseas. I personally have been sitting on a pile of crank/bb's, forks, stems, bars, frames, and hubs, stuck waiting to see how conditions improve here before launching anything. The Canadians are very happy & willing to do any work, on the other hand.
honestly i could produce these with minimal equipment ......man i have to start buying some machines and some tools soon....
I bought some from Proshox, (Ebay) for my trance. Fit & finish exceptional. It helped slack out the head angle, & allowed me to use a longer travel shock as well.
Ok, out of curiosity...I'm trying to wrap my head around tweaking head angles with these, or even anglesets. Wouldn't it make more sense all the way around to just go with the geometry you're looking for in the first place, from a design standpoint?
Thats great and all if you have the money to just get a new frame, but a lot of times that bike also doesnt exist. Only in the last couple of years has their been slack and low all mtn/enduro bikes. Before, all mtn bikes were just long travel xc bikes.
