Bike Reviews Gas Gas TXT Pro Range
To say that trials is pretty much a specialised sport is to drastically understate the case.Trials riders are in the main very clued-up on their sport and know whats what which is why carrying out bike tests is often no easy matter.
Most riders know exactly what they think about certain marques and models and sometimes all we do is confirm what they already know.
But it never hurts to get back to basics and start the evaluation from scratch.
Every trials rider knows pretty much exactly what a Gas Gas is and what it does. Yet we would argue that a Gas Gas from even three years ago is very different to what you get now - for several reasons.
The range got a comprehensive redesign last year, which was a major step forward and the Gerona factory has made some pretty big strides in the quality department even in the last six-to-12 months.
Some of the most recent are a direct result of Dougie Lampkin's involvement.
For 2011 the Gas Gas chassis was completely redesigned, and while the basic, simple, steel-tube perimeter frame remains intact, the rear section was replaced with a practical and visually pleasing tubular arch structure making up the rear shock mount.
This in turn allowed a total rethink of the exhaust and airbox design, with the end result effectively removing all previous criticism of either function.
It was the biggest and best redesign by GG since the introduction of the PRO series.
The engine and six-speed box, still one of the smallest, most compact units around, sits neatly in the chassis with the latest Marzocchi forks up front and the expected aluminium swinging-arm at the rear, controlled by a new Sachs rear shock, fitted with a new design spring and new linkage ratio.
The white painted forks are a contrast to the previous black version and they allegedly offer less stiction.
One change which is making its way into production is new brakes - courtesy of Italian manufacturer Formula. These look very trick and show obvious mountain-bike influence sporting short, adjustable, folding levers.
But are they actually any better? Here are some tasty photos to sink your teeth into, enjoy.
