Full description and spec

Size guide and geometry


Titanium has a well-earned reputation as a wonder material. No other metal can match it for strength-to-weight ratio and no carbon frame can beat it for durability and ride feel. It blends the handling feel of the best steel bikes with the low weight and efficiency of carbon. Titanium bikes always stand out from the crowd with looks and longevity that are peerless at any price; with subtle brushed 'Invasion Stripe' detailing the Spitfire is no exception. Everyone should have at least one titanium road bike in their collection.

With geometry designed by master frame builder Mark Reilly, the Spitfire was created first and foremost as a competitive road machine. It offers predictable handling with a moderately aggressive riding position that will be instantly familiar to anyone who's spent time aboard our EC-130E Aero Road bike. The Spitfire's rear triangle features ovalized and tapered frame tubes that provide subtle vertical compliance. Triple butted, ovalized seat and down tubes mate to a 68mm bottom bracket shell to provide a firm, responsive pedaling platform. The Spitfire offers classic racing performance with a welcome touch of comfort.

If you're hunting for a new road bike but find that modern carbon bikes leave you cold, spread your wings and give the Spitfire a try.

The Selcof Delta SL Fork sets new standards for stiffness and low weight. Incredible torsional stiffness ensures pin point steering precision and accurate tracking while an elegant profile and carefully considered layup ensure it's capable of smoothing out rough road surfaces.

The remarkable 320g weight has been made possible by our use of High Modulus carbon fibre. We've trimmed every gram of spare to leave just the pure performance. This fork has already earned itself a huge reputation with competitive hill climbers. When every gram counts trust the Selcof Delta SL.
