Specialized Alibi Step Through 2017

With its airless puncture proof tyres and its innovative rust-resistant chain, Specialized's new Alibi might be the most practical traditional 'ladies' bike you can buy.

This bike features Specialized's new Nimbus Aireless tyres which can't be punctured and will never need inflated. Never again will you suffer the sinking feeling of going to the shed to wheel out the bike, only to discover it has a flat tyre.

  • Nimbus Airless tyres are filled with a 'blown' foam rubber as used by the likes of Nike to cushion their sports shoes.
  • Nimbus Airless tyres therefore have an element of comfortable compliance, lacking in previous attempts to create viable non-pneumatic tyres.
  • In blind tests, few riders could discern the difference between Nimbus Airless and the regular air-filled Specialized Nimbus tyres we have been selling for over 20 years.
  • The Specialized Alibi's wheel rims are specifically designed so the Nimbus Airless tyres fit them perfectly to ensure the tyre won't slip on the rim when cornering (as can happen with aftermarket 'solid' tyres).
  • The rims are drilled and will take a regular pneumatic tyre and tube on the off-chance you ever decide to go back to conventional rubber.

More Alibi innovation

  • Rust-resistant KMC chain.
  • Specialized reckon the Alibi's chain is the most rust resisitant they have ever tested.
  • Not bad when you consider the variety of chains Specialized have fitted to the millions of bicycles they've built over the past 35-plus years.
  • Its bang up to date Shimano 1x7 transmission offers a decent spread of gears (14-34 freewheel) in a simple single shifter, single chainring format.

'When it comes time to ride, the last thing you want to do is fix this or pump that, right? We hear you loud and clear, which is why we made the Alibi Sport Step Through to be ready to roll whenever you are. It has a step through frame design that makes getting on and off the bike as easy as can be, an anti-rust chain that removes the need for dirty, grimy maintenance, and puncture-proof, airless tires. That's right, these tires don't need any pumping and they'll never go flat. As for the ride, the Alibi has a wide range of gears, courtesy of Shimano, that'll get you over any hill that stands in your path, plus supportive Body Geometry grips and saddle that are designed specifically for women. You'll never need an "excuse" to ride the Alibi.

  • The hard-working & sturdy A1 Premium aluminium frame is light and durable, and it also features rack and fender mounts for easy portage and dry riding in wet conditions. You'll also find that it's engineered with our Fitness Geometry, meaning that you'll go fast with maximum efficiency, but without the discomfort of an aggressive ride position. After all, the more comfortable you are, the longer you'll ride.
  • The Alibi's anti-rust chain keeps rolling smoothly, even after a couple of confrontations with the elements, so you can spend more time riding and less time fixing.
  • There's never a good time for a puncture, which is why the Nimbus Airless tyres feature a puncture-proof core, offering incredible traction without the hassle of changing a tube.'
