hey i noticed that theres multiple shock mounts on the bb7. whats the ideal setup? right now its on the top one on the swingarm and the lower one on the frame. whats the best way to set it up?
bb7 shock mounts

Not to sound like a total jerk, but the best way to set it up is to go out and ride it in all the settings and see what feels best to you. I'm guessing that one combination of holes will give more or less travel and another combination will make the rate more or less progressive, be sure to tinker around with the shock too after moving the mounting bolts before deciding that one setting feels like crap. Because the angle of the shock relative to the swing arm's path changes slightly with each setting things like progression, spring rate and damping will be affected.lovebunny said:
yeah im worred bout changing it though because i hear that in certain settings it practicly kills your shock. and i cant take it out yet because i dont have a chainring and the springs too stiff for me. that all should change this week though. and form what ive ridden w/ out pedaling on short stuff it feels way better than my bighit did and this things setup way off so im thinking its gonna be an orgasm to ride once its setup right
If you're talking about a 9" travel BB7, there are only two upper shock mounts. The upper hole in the upper shock mount is the standard setting while the lower hole is for bumping up your BB height and giving your a steeper head angle.
i thought the lower hole was the strip-the-paint-off-your-bike setting?ChrisRobin said:
Actually I think the 03 BB7 had two mounting positions on the frame, as you can see in this pic:

I would assume that the different positions effect the rate of the shock. So the hole closer to the bb would be more progressive. (Assuming that's actually another mounting position)

Uhhhh yes, howd you know that!zedro said:
Right, I forgot about those...just make sure everything fits ok before using the bike: as in making sure nothing is touching or rubbing.
yeah i got a lil of that on mine form the previous owner.zedro said:
On my 02 BB7, I run it in the bottom hole on the swing arm normally, steepens up the steering BB height is increased too but I'm not too worried about that.
On steeper stuff I change it but thats only been twice.
My biggest problem is the the axle to crown on my old S7's is super loong so its pretty much a chopper no matter which way you look.
The lower mount hole?? I cant see bike from here but I don't think it has it. I think that those holes are for 5th Element shocks???? maybe??? I'd swear I heard someone tell me that somewhere, somewhen??
BTW is the bottom end of your shock super tight in the frame, I have to put a broomstick thru that hole near the BB and tap it to get shock out?

I run my 2001 in the bottom holes on the swingarm links. I found the bike more stable in the top holes verses the bottom holes probly becaue of the lower bb and slacker head angle in the top hole setting, the 2001 has only one hole for the bottom of the shock, yours has two?
and yes i do belivve that on the 2002 and later bikes that useing the lower holes put the swingarm links high enough that yes the paint would be damaged.

On the '03 bb7, there were 4 shock mounting holes, two up top and two on bottom. On the swingarm, the top mounting hole will give you a slacker head angle and lower bb height, while the lower mount will steepen the head angle and raise the bb. Here are the measurements from Balfa:
Upper Mount - 67.5* Head Angle, 14" bb height
Lower Mount - 66.5* Head Angle, 14.75" bb height
On the lower mount, the hole closest to the bb is the more progressive setting, while the one further away is the linear setting. If you have a 5th, keep it in the linear setting (no need to have the linkage set up progressive when you have a progressive shock).
Hope this helps. Here are some pics, hot off the presses, just finished polishing up my baby, waiting on a chain.

Yeah mine takes some doin' to get it out. Same with the upper mount, but it's not as badJoeRay said:

Oh, one more thing you wanna watch out for. I noticed in the upper shock mount on the swingarm, my mich comp 24.1 2.5" was rubbing the screw for the mrp guide, so that would either need to be grinded down/replaced or you'd have to run a smaller tire. Just something to think about.

On most frames the S7's height isn't a big problem. The BB7 has such a short headtube that you pretty much have no choice running a boxxer or a dorado fork. I had a choice when I was using my S7 with my BB7: either have it choppered out or lower the fork on it's stanction tubes and run a 100mm stem.JoeRay said:
I ran mine in the lower, strip off the paint hole. This made the HA steeper per my liking. I ended up grinding a bit of the plate to keep it from rubbing off more than paint.
As for the lower shock mount holes near the BB. They should make the shock more progressive, but I couldn't tell the difference between the 2.
ps, your spring is in the mail

or the fact its a single pivot and wont really get that much (any) progression anywaysskyst3alth said:

yo, LB, why didn't you just email me!!!! I could have let you know anything about the frame....I am the one who you bought it from. btw, I have the owners manual for the frame and the shock. get me your address again and I'll see if I can get it out in the mail.
I've dished my wheel about 8mm to the left to compensate.skyst3alth said:
Yes, its a pretty ghetto thing to do and the front wheel no longer is in the same line as the back.
All I care is that I can run 2.5s and not have rub against my MRP.And the way I ride its not like its going to impede my performance or anything. As a plus it may make the wheel a bit stronger cause there is 'less' dish in it.
That would work. I was thinking about finding a bolt with a flat head on it instead of the rounded one to use, so I could try out the lower setting. We shall see though.JoeRay said:I've dished my wheel about 8mm to the left to compensate.

Yeah and then grind down the linkage so my purrdy paint won't get ruined.

me 2 bud i still need a damned chianring, hope i order from goride tomorrow. also found a nice deal on a floater aswell as a bb so im set

If you run the bb7 with a evil chainguide you can run a 2,8 michelin c32.
there is a guy that has posted pics of his -04 bb7 in that setup. search for RogerH.
i put a washer inbetween the linkage plate and the round shell that's surounding the bolt and it worked fine.
