Tifosi Rostra Caliper Centaur Bike

Rostra Caliper Centaur Bike The new Rostra Caliper is the evolution of Tifosi's ever popular CK7. It is the perfect aluminium all-season bike that is capable of handling year round British weather, long commutes and fun weekend rides. A Lightweight 6061 T6 aluminium frame ensures excellent ride characteristics and durability alongside comfort-oriented geometry, while the unidirectional fork with 1-1/8" to 1-1/2" tapered carbon steerer gives precise steering but with the additional comfort that carbon fork blades give. The X44 headtube works with most modern tapered forks and aids handling, future-proofing the bike for years to come. Disc fitment is flat mount standard for hydraulic or mechanical and 12mm thru-axles keep everything stiff and secure. Without mudguards the bike can take up to 38mm tyres, when fitted, tyre clearance allows for up to 35mm. The Rostra Caliper also has additional mounts for pannier racks if required. Designed and assembled in the UK.

Surly Straggler 650b Rival 1x Gravel Road Bike

One By version of the Surly Straggler So what is this Straggler anyway? The easy answer is to say that we added disc brakes to a Cross-Check and this is close to accurate. People have asked us to make a disc version of our highly versatile Cross-Check for a long time now and almost everything about the two are very similar. Straggler is slightly different, though. The most obvious difference of course is that the Straggler has disc caliper mounts instead of rim brake studs. It'll accept rotors up to 160mm. The rear dropouts are unique, too. They're a partially closed horizontal design that accommodates singlespeed or geared drivetrains. They feature stop screws that thread in from the rear to further secure the wheel and to position the rear wheel for optimal shifting, plus a forward-mounted stop screw on the drive side to keep the wheel from slipping forward under the force of your gargantuan legs. The rear dropouts are spaced 135mm instead of 132.5mm like the Cross-Check simply because there are far more options for disc hubs in this spacing. Straggler shares all of the Cross-Check's braze-ons for fenders, racks and bottle cages. The Straggler's geometry is slightly different, with angles and tube lengths very close but not identical to the Cross-Check, but like the Cross-Check it's ready to take you just about anywhere. It's a day tripper and a weekender. It's a "rough road" road bike. It's a cyclocross bike with no pretense about racing. It's a utilitarian townie. It's a light-duty touring bike. It's an all-weather commuter. And when you get tired of one set up, you can swap parts around and turn it into something else. We think that's pretty neat.
