Marzocchi 55 ATA2 review£449.95

Proving a big hit: nicely progressive mid-level long-travel fork

BikeRadar score4/5

The 55 is a whole new fork for Marzocchi and this mid-level model is proving a big hit. Big bottom end, brace and crown with 35mm stanchions and QR20 screw-through axle give impressive stiffness, at a good weight.

The stroke is smooth with nice progression added by the low pressure air spring. There’s no obvious empty spots bar occasional rebound/top-out clunks off big drops and it’ll take on long step/rock sections without worry. Apart from the fact it’ll hurt your fingers, the ATA2 travel winder works well through 120-160mm (4.7-6.3in).

It’ll suit many bikes and the TST2 gives basic compression control to stop climbing/braking dive. We’ve run several ATA2s without problems.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
