The Trailstar is an absolute classic frameset, on the market for 20 years now and long known for its aggressive geometry that is more than capable of handling the toughest of technical offroad terrain with ease. Its latest incarnation is still 4130 CroMo steel as before, but these days it boasts modern touches such as 27.5 inch wheels, stealth dropper post cable routing, single ring specific and tapered head tube among many other design tweaks to keep it up to date.
A slack head angle of 66 degrees, long top tube and compatibility with a long-travel 150mm suspension fork mean it is as at home jumping around your local woods as it is ripping through fast mountain singletrack.
It isn't the lightest frameset in the world, but it has to be one of the toughest and most fun. It is also versatile, with the rear dropouts interchangeable to allow for 27.5+ size tyres - extra wide rubber handy for mud, snow or soft ground.
