Product Details

Marin Four Corners 2018

An informed mix of old school (butted chromoly steel frame) and new school (disc brakes and a Shimano STIs) the Marin Four Corners is one very impressive touring bike.

Slim tubing
The Marin Four Corners' butted alloy frame looks anorexic by today's fat tube standards. You'll agree skinny tube are good thing when you experience this bike's light sprung feel.

  • 4130 butted chromoly steel frame for lightweight, durable strength.
  • 73 degree seat tube/72 degree head tube geometry - classic fast touring bike geometry.
  • The tall head tube (compared to a regular road bike's) allows a slightly more upright position for enjoying the view.
  • The frame is fully eyeletted.
  • If you would like us to fit mudguards and racks (or anything else) just ask when you order the bike and we will waive the normal fitting charge.
  • Shimano Sora STI gear shifters and mechs for smooth gear changes.
  • STI means Shimano Total Integration. The shifters are integrated with the brake levers so you can change gear any time without having to take your hands off the brake lever hoods.
  • The Shimano Sora Hollowtech 2-piece crankset and bottom bracket are lighter weight and more flex resistant than traditional chainset designs.
  • The 50/39/30 Shimano chainrings and the 11-32 Shimano cassette offer a wide range of gears that will help you up near-any ridable hill and won't spin out on fast flat sections.
  • Reliable Tektro Spyre-C Road Mechanical Disc brakes with160mm Rotor.

The Benefits of Disc Brakes
Proven for over a decade on mountain bikes and better quality hybrids, the benefits of disc brakes are now becoming more and more recognised on road bikes and touring bikes.

  • Moving the brakes from the mud and rain-attracting wheel rims to the relatively clean hubs makes for an improvement in the brakes' all-weather all-conditions performance.
  • Disc brake pads are much harder so they last much longer.
  • That's why disc brakes tend to need far less maintenance compared with rim brakes - they don't require such frequent adjustment to compensate for brake pad wear.
  • The wheel rims should also last much longer now that they are no longer being worn down by the brake pads.
  • On touring bike like this, moving the brakes away from the rims maximises clearance for mud and mudguards.

'The Four Corners is built for today's commute and tomorrow's adventures. We've updated the fit based on biometric data, and for 2018 offer five different frames sizes with size proportionate 650B or 700C wheels for riders 4'11” – 6'4”.'
