This GT Pantera is a great example of an affordable and reliable commuter. After we perfected the process of refurbishing vintage road bikes (10 speeds) and than english 3 speeds, we took on the challenge of refurbishing the early mountain bikes made from the late 80's to the late 90's. The correct term for these bikes is "Rigid" as they have no suspension, unlike the hardtail (front shocks) and full suspension (front and rear shocks). I have a lot of respect for these bikes as I used to race rigid mountain bikes back in the days when suspension was still considered unreliable and energy waster (the shock absorbs some of the pedaling energy) plus they were not that efficient as the early hardtails did not have more than 2" of travel (the distance the shock compresses).
GT was a strong player in the Mountain bike scene throughout the 90's. This early GT Pantera has an Aluminum frame and a U brake in the rear but the location is quite unique, placed on the seat stays unlike most U brakes which were located under the chain stays. U brakes were wildly popular between 1986 to 1988. They were very strong but due to the location under the chain stays they were hard to service without flipping the bike up side down and also were basically mud traps when you actually took it off road. The GT Pantera screams early 90's Orange-pink Neon paint scheme and punk-rock style decals. The goal in refurbishing bikes like the GT Pantera is keeping it under budget as these are the most affordable bikes in our shop. The parts these bikes came with were quite hi tech but not all of them survived, especially the Suntour thumb shifters which were not as good and crisp as shimano's. We had to replace front shifters since finding quality thumbs shifters is quite hard these days. We ended up replacing the tires to the semi slick and thin type  We had the chain and freewheel replaced along with a comfortable suspension seat post. All the cables, brake pads and some of the housings were replaced as well. GT was a unique company and were readily identifiable due to the famous triple triangle geometry which, in my opinion, was mostly a gimmick. GT merged with schwinn in 1998 and was later bought by the pacific company and than by the dorel industries bicycle conglomerate. 
sold to a nice girl looking for a reliable point A to B bike for short commutes in the somerville area.

    1994 Cannondale M300 we refurbished here at Bike Boom. If your'e not familiar, Bike Boom is a used bike shop in Davis square, on the border of Cambridge and Somerville , near Boston MA. where we specialize in restoring and refurbishing used and vintage bikes and offer professional bicycle repair services.
This is one of my favorite refurbs we did this year. Throughout the Nineties,  mountain bikes based on this frame brought cannondale it's fame among mountain bike riders and later to the road bikes scene. Admittedly, cannondale started it's bicycle business with road bikes (they made trailers and riding gear at first) but were a very small bicycle company before the mountain bike boom of the 90's. More on cannondale's history from MOMBAT.  Cannondale has a huge following and a vintagecannondale.com is great website with old brochures and serial numbers info, a must for every vintage cannondale fan.
This M300 was cannondale's entry level mountain bike and when we received it, we were not surprised to observe that most of the original, low end parts have been replaced over the years with mid end ones. The famous fat tube frame though was in perfect shape, with just a few marks. We ended up replacing the cockpit (stem and handlebar) to a more upright riding position and replaced the rear wheel with a brand new one and a newer matching front wheel. Finally , new 1.5" semi slick tires were installed, which resulted in a fast, light and upright, effortless riding position. A great bike for a short (2-5 miles on average) daily commute, campus ride or "ride to the subway station and park" kind of bike. Most of our customers commute fits this description, and being our most affordable bikes makes them very popular around here. Modern mountain bikes are considered slow for road riding since they are heavy due to the thick tires and suspension but also because they are equipped with a small front chain rings (crank). In the late 80's and early Nineties  they lacked suspension forks and came equipped with a relatively large crankset (48, 46  or 44 teeth count on the large chain ring)  compared to modern mountain bikes from the late 90's and on with only 42 teeth on the large chain ring. this means these bikes, though not racers can actually achieve relatively high speeds. 
Today, a proper mountain bike must have at least 3" of front suspension , so the new version of these rigid mountain bikes converted to city bikes are called by the leading bicycle companies, "city commuters" or "comfort bikes", which are basically a hybrids with round profiled mountain bike wheels (26", instead of 700c) What can I say, Marketing can perform miracles.
