Trek has announced the release of its new Farley fat bike, featuring 27.5x4.5in tyres.
The brand has said the bike has had a full overhaul from the previous incarnation and features a new alloy frame and 42mm-offset carbon fork with rack and cage mounts.
Four versions of the Farley are available. The aluminium-framed Farley 5 and the carbon-framed Farley 9.6 will be available in the UK.
The Farley 5 is priced at £2,130 / $2,199 / €2,299, and the Farley 9.6 at £3,525 / $3,699 / €3,799.
The new Farley uses SRAM’s Universal Derailleur Hanger and a 100mm threaded bottom bracket.
Trek says the Farley should be available from mid-March.
Fat frame
Trek’s new Farley will be available with a carbon or aluminium frame, depending on the spec level.
These frames are also available separately, with the aluminium frameset priced at £1,390 / $1,499 / €1,499 and the carbon frame at £2,590 / $2,599 / €2,799.
It is only the aluminium frame that has received updates. The Farley 9.6 uses the same carbon frame as the previous model.
Trek says the new aluminium frame features modern tube shaping with added mounts for expedition gear. This includes top tube bento boxes, frame bag mountain the front triangle, down tube bottle or mudguard mounts, and updated rear rack mounts.
Geometry updates include a slacker head tube angle, decreasing from 69 degrees to 68.5 degrees for a size-large frame.
There is also a longer reach measurement, up from 441mmm to 460mm, as well as shorter chainstays, down from 455mm to 450mm. Both figures relate to a size large frame.
The new carbon fork features an offset of 42mm, as opposed to 51mm on the previous model.
Trek says the carbon Farley didn’t get an upgrade because it felt the bike was still a "benchmark for fast and light fat bike performance".
The maximum tyre size for the Farley is 27.5x4.5in when mounted to 100mm-wide (internal) rims.
The frame also features full internal dropper routing, enabling you to use a variety of dropper posts.
