If you continue to use this site we will assume that you are happy with it. This can result in pedal strikes and the suspension going through it’s travel too easily, and “bottoming out” often, and with rear shocks, this can result in pedal strikes and less pedaling efficiency. Another method: with all Cane Creek Double Barrel coil shocks, you can dislodge the bottom out bumper from the spring clip and use it as a travel indicator o-ring like on an air shock. However, they weren't available in the short length. Go to the pictures and let the captions explain how I did it. Rear shock hardware is labeled first by the width of the hardware axle, and then by the diameter of the mounting bolt. I just think that kind of detail gives parts a more finished look. I'm positive this is all redundant stuff to most folks and probably crude compared to the way the billet boys build their high-buck rides, but I just thought I'd pass it along. Slide the travel indicator o-ring all the way down to the wiper seal: Being careful not to bounce the suspension, dismount the bike. Then a series of short cuts are made to the pencil line. Note how all of the edges are broken and sanded to a slight radius and the edges of the holes are gently chamfered with a big (5/8") bit. To cut the radius a long cut is made from either corner of the radius that intersect as close to the middle as possible. The distance between the frame, where I wanted to put the shock mount, and the rear end axle tubes was such I could only use Pete and Jake "shorties." You must confirm the width of the hardware axle in millimeters, (or the distance between the shock mount tabs) and the diameter of the eyelet that passes through the hardware axle (or the diameter of the mounting bolt). Hardware axle and spacers. When you have too much sag, you do not have a high enough spring rate to support your rider weight. I soon found I was banging my head on the wrong wall anyway because, when I put the shocks in place it turns out the cover would have hit the rear cross member big time. Stroke length refers to the total distance the shock can compress. A bushing is needed to allow for some rotational movement of the hardware axle when the rear linkage pivots – If there were no rotation allowed at all between the shock eyelet and the hardware axle, the rear linkage would not move freely and the rear shock would absorb all of the extra leverage, which is not ideal. Probably a real dumb question but I just bought my first mic with a shock mount and have no clue how to put this thing together. Road
I wasn't about to butcher up the little "tunnels" I had made through the fender wells for any reason. Put your shock pump back on, then pump the shock up to around your rider weight. If that information is not available to you, we recommend 25-35% sag depending on your shock size and intended use.
You can measure the stroke length by subtracting the eye to eye length when the shock is fully compressed, from the eye to eye length when the shock is fully extended – you should get relatively close to the shock’s stroke length. A Trunnion mount shock mounts the shock body directly to the linkage – there are two threaded holes on the shock body and linkage bolts thread directly into them. Sag affects the geometry of the bicycle, and frame designers design frames with geometry and sag in mind – ideally you would want to experience the bike in the way it was intended and designed to be ridden. 3. If you have any further questions about one of our shocks, feel free to contact us. In this case, however, I thought I'd show the process of doing fittings one at a time, going left to right: Oops! My choice of where to mount them on the differential was pretty much made for me too: Since the body was channeled, the edges of the fender wells came down over the axle tubes.
They are easily replaceable, and we replace them during every in house factory direct service. That bottom out bumper can affect the measurement you find by a few millimeters. That bottom out bumper can affect the measurement you find by a few millimeters. refers to the total distance the shock can compress. Take the pump off and cycle the air through the shock again. A mounting bolt (that comes with your bicycle’s frame) will pass through the hardware axle and thread into the frame or the frame’s linkage, which secures the hardware and shock in place. Mounting bolt holding rear shock mount in … The first step is to confirm the eye-to-eye length and stroke length of the shock. In most cases, there is a bushing that is pressed into the shock’s eyelet, which the hardware axle is then pressed into. Find a flat surface and have your normal riding gear on and get into a ready position, and try not to move. Home » Everything You Need To Know About Rear Shocks. Then I drill the holes and bandsaw all four at the same time, which guarantees all of the parts match on another. It’s important to note: the preload adjustment on coil sprung shocks only affects sag. This gets rid of most of the material. Second, I think tube shocks look very cool. You will use the proprietary mounting hardware that came with your bike’s frame on a 15mm open end eye mount. In most cases, a bottom out bumper is incorporated at the end of the shock’s stroke, which helps deter harsh “bottom-out’s” when the shock compresses all the way very hard. Be aware that the threading comes in certain sizes, with ⅜” and ⅝” being the most common. I don't know how the Boyd Coddington's or Pete and Jakes of the world would do it, but this is how an over-the-hill teenager from Nebraska did it. A bushing is needed to allow for some rotational movement of the hardware axle when the rear linkage pivots – If there were no rotation allowed at all between the shock eyelet and the hardware axle, the rear linkage would not move freely and the rear shock would absorb all of the extra leverage, which is not ideal. We use cookies to ensure that we give you the best experience on our website. Eye-to-eye length is the distance between the two mounting points on the shock, or the rear shock mounts on the frame. In most cases, a bottom out bumper is incorporated at the end of the shock’s stroke, which helps deter harsh “bottom-out’s” when the shock compresses all the way very hard. I normally make multiple fittings by stacking the number of blanks needed, in this case four, on top of one another and welding the corners. Where the beads run on the top pieces, I've ground a chamfer in the edges of the top plate so most of the bead is below the surface. They are easily replaceable, and we replace them during every in house, Rear shock hardware is labeled first by the. 4. Some newer microphones, such as the Neumann TLM 102, sport an internal shock mount, i.e. In this case, you would want to drop some pressure out of the shock so you could get closer to 25-35% sag. The pattern outline is penciled on to flat stock (3/16") that I've hit with a thin coat of sandable gray primer so it'll take the pencil better. Take your shock pump off and find a place to cycle the shock through it’s travel 15-20 times. So, I made a set that was a little longer (rear). The shock didn't have enough clearance at the top. The final product. The type of hardware we use and install into our Double Barrel shocks is a traditional axle and spacer assembly. This is to ensure that the positive and negative air chambers are equalized. A mounting bolt (that comes with your bicycle’s frame) will pass through the hardware axle and thread into the frame or the frame’s linkage, which secures the hardware and shock in place. A Trunnion mount shortens the overall eye-to-eye length of the shock while allowing it to have the same amount or more, of shock stroke. Gravel / Adventure / Cyclocross, Everything You Need To Know About Rear Shocks, It is important to understand that your rear shock size on your full suspension mountain bike is not measured by the amount of rear wheel travel, but by the.
