Bike Test: GT Xizang 9R
Back in the ’90s, the GT Xizang was highly coveted by cross-country racers everywhere. Based on the popular Zaskar’s geometry and using GT’s signature triple triangle frame design, the Xizang took things one step further, as it was built from titanium rather than aluminum.
Flash-forward to 2012. GT reintroduced the Xizang as a frame-only option, complete with modern updates, most notably GT’s take on geometry designed for 29-inch wheels. While the Xizang is only available as a frameset, GT wanted to show off its titanium beauty. GT handed the Xizang off to the highly respected Newbury Park Bicycle Shop in Newbury Park, California, and asked them to build a one-off, no-holds-barred bike with parts riders in the ’90s couldn’t have imagined in their wildest dreams.
WHO IS IT MADE FOR?
The Xizang’s cross-country roots run deep, and the modern iteration certainly pays homage to that history. The Xizang is built for cross-country and trail riders, especially those who were riding during the original Xizang’s time; however, the appeal of the Xizang doesn’t depend on the pull of nostalgia alone. Riders who weren’t lusting after the original in the ’90s will still appreciate the Xizang’s craftsmanship and attention to detail.
WHAT IS IT MADE FROM?
The Xizang’s frame is constructed from 3AL-2.5V titanium, with a clear-coat finish to show off the perfect welds. While it sports GT’s classic triple triangle design, modern features include a tapered head tube, hydroformed seatstays and chainstays, post mounts for disc brakes, and a replaceable derailleur hanger.
The frame’s steep, 72-degree head angle and 73-degree seat tube angle, along with the relatively short 17.5-inch rear end, make the bike’s cross-country designation clear.
WHICH COMPONENTS STAND OUT?
Every component was handpicked by GT to complement the bike. The merging of modern technology and retro aes- thetics is definitely impressive. SRAM’s groundbreaking XX1, 11-speed drivetrain keeps the weight low and cockpit clutter to a minimum. Formula R1 brakes with carbon levers and braided hoses are jewelry for the Crankbrothers handlebar. The Thomson Masterpiece seatpost is beautifully understated. The wheels offer custom-built Reynolds carbon 29er rims with Industry Nine anodized hubs. GT even had custom colored-matched graphics made for the Xizang by Complex Ink to tie the frame into the hub and fork stanchion tube colors.
HOW DOES IT PERFORM?
Moving out: The rider position is fairly centered over the bike, with a slight weight bias toward the rear. The standover height is tall compared to modern, sloping top tube designs. Thankfully, the ergonomics aren’t modeled after those of the ’90s, and the Crankbrothers handlebar and stem give the cockpit a solid feel.
Cornering: Within one turn on the first trail, we were amazed by how quickly we could whip the bike around a 180-degree switchback. The front end’s 72-degree head angle provided a serious dose of low-speed maneuverability.
This quick steering is, however, a double-edged sword. As you pick up speed, the Xizang becomes twitchy. It took us a while to get used to how sensitive the bike is to rider input in fast, sweeping corners. This bike demands finesse.
Climbing: The Xizang remains true to its racing roots. Its impressively light parts spec means instant acceleration when you put power to the pedals on climbs. GT’s triple triangle frame aims to increase stiffness, and, along with the hydroformed rear end, it does just that. While many titanium bikes feel a bit flexible under hard pedaling, the Xizang is remarkably stiff.
Seated climbing is less inspiring. The same stiffness that gives the bike impressive acceleration creates a lack of vertical compliance. Though titanium bikes are often known for their softer ride characteristics, the Xizang’s ride is harsh.
Descending: Ripping down descents, you will be reminded of a time long ago when it took finely honed skills to get down the mountain quickly and in one piece. The bike’s unforgivingly steep front end and quick handling forced us to pay close attention to technique. With the steep geometry and the saddle elevated to cross-country height, we found ourselves dreaming of a modern dropper seatpost more than once.
Braking: Formula’s R1 brakes offer great power and modulation and are beautiful components in their own right. With polished-silver levers and calipers, as well as carbon lever blades, the R1s add some bling to the Xizang. Our only gripe was with the levers’ ergonomics. We much prefer Shimano’s or Avid’s lever feel.
TRICKS, UPGRADES OR TIPS?
Know going in that the ultra-stiff Xizang frame lacks vertical compliance. We highly recommend focusing on reducing the harsh ride when choosing components for your Xizang. Opt for a more forgiving seatpost, such as the Niner RDO, which will dampen some trail feedback during seated pedaling. We’d go with larger-volume tires (there is plenty of room) to add cushioning to the rear end. Finally, lock-on-style grips in the largest diameter comfortable will reduce the sensation of jolts and vibrations in your hands and arms.
BUYING ADVICE
There is no denying the level of craftsmanship that goes into GT’s new Xizang. With perfect welds and beautifully hydroformed tubes, the Xizang is a work of art, and an amazing parts spec ties the whole thing together.
While the Xizang is beautiful to behold, the steep geometry and unforgiving ride mean that it’s not the bike for everyone. The Xizang will appeal to nostalgic riders who always yearned for one of these titanium beauties back in the day and who love the idea of building up a revived piece of mountain bike history with modern amenities.
