Rolling In Style

Ten years ago, I discovered this frame on eBay. I wanted a full suspension set up, but had pretty much given up on finding such a frame that wasn’t stupidly heavy for My purposes. I was looking for a light weight mountain bike frame to build up for riding the city streets. This beauty weighs in at 4.55 pounds, that is the frame, shock and the black seat mount together. It just doesn’t get any better than that, unless You want a rigid frame. It was made by a company called Amp Research, formerly Amplifier, in the late 90’s. Originally, these bikes came with disk brakes, the first bike ever with disk brakes in fact. Though that made for some complications in My build. Now, there are standard mounting points for brake calipers and rotors, but since this was before standards came to being, the only ones that work are the original Amp brakes. Unfortunately Amp Research is an engineering group, that dabbles in many different types of things and at the turn of the century, they ended their decade-long run making bicycles. Needless to say, finding all the hardware, without buying another one of their bikes, whole, was not an easy task. Over the next couple years, I actually bought two more variations of them. This one aquired on auction from a police department in Michigan.

Only the frame and fork were from that auction, along with a set of the old Amp disk brakes. These black and white bikes were originally made for the New York police department, amp added the rack to their standard issue Mercedes-branded bikes and sold them to cops around the nation. I love the front fork on this bike. A second generation Amp model, which has a mere two and a half inches of travel, but they are so smooth and absurdly light. This is a B3 series frame set. Which recieved all of the rest of it’s components, less the brakes and wheels, from My old specialized rock hopper. I bought the Vuelta wheels and a set of Shimano IS Hydraulic disk brakes once I figured out an adapter to be able to mount the now standard brakes. Which was a four year hassle that eventually led Me to sell this bike in frustration. The front worked just fine, but the rear brakes were mounted in a pretty shody way. At least I doubled My money on it.

Shortly after selling that bike, I found an Amp F3 front fork, with the carbon fiber pipes, from their last(B5) frame. I proceeded to replace the Girvin Cross-Link Elite that had been on My silver B4 frame for 5 years. This was a welcome change, since the old Girvin fork was nearly twice the weight. Oddly, the carbon fork is actually heavier than the older, all aluminum one. It does have a longer range of travel, but it is not as smooth as the elder fork was either. It does match the carbon rear end of My frame and the bike is much nicer to ride than it was with the cross-link on it. I must admit though, I liked the look with that girvin fork too.

I was happy to aquire My third Amp Research bike(not pictured) because it had the v-brake clamps. If I had not worked out a way to run them, I would have had to switch to some regular wheels and run the same lack lustre rear disk brake arrangement as on the police bike above. I really did not want to take the non-disk braking, carbon composite Spin Tri-Spokes off of this bike. They just look so great and if You haven’t connected the dots, just think, Mercedes-Benz logo, only they are the wheels. Yeah, I went there… Having rode this bike for 4 years with only front brakes, clamping on the mounts for the rear end was a nice feeling. So was the feeling of being able to stop really fast, without flying over the handlebars. Six years after getting the frame, the bike had reached what should be it’s final incarnation. I wish I could have fit a larger front gear, but the angle of the lower-rear fork will not allow more than the 48 tooth that’s on it. She rides like a champ, quite fast, easy to accelerate and it has a firm ride, but takes the edge off of those massive Minnesota pot holes.
