Bundled in with their new 50mm carbon clincher wheels, titanium frame builder Spin brought by the updated Spitfire MK II sportive bike and the reintroduced MK I entry-level race machine.
We’ll start with the former; the updated MK II, the MK IIA, features slightly slacker head and seat tube angles than its predecessor (in a size medium, both down half a degree, from 73.5º to 73º and 73º to 72.5º respectively). Along with a 1cm increase in head tube size (148mm) across the range for more upright position on the bike, it further emphasises its long-distance credentials. To keep the wheelbase unchanged, the chainstays have been lengthened by 5mm (now 410mm) which allows greater tyre clearance.
It remains fully customisable, as is the case with all Spin’s frames, and starts from £1,090 for the frame only. The build as shown here comes in at £2,899 with Spin’s own carbon fork and handlebars, titanium headset, stem and seatpost, and Speed Metal 40mm wheels. SRAM Apex components (with 12-27T cassette), elliptical ROTOR Q-Rings (52-36T), Schwalbe Ultremo tyres and a Fizik Arione saddle make up the rest of the spec.

Spin MK I
The bike that Spin first made their name with is back. The MK I was sidelined when they branched out into other bikes like the MK III, but the same bike is available once again. It’s unchanged from its original guise, so you get a titanium entry-level racing frame for £990. Given it’s a racer, it has steeper head and seat tube angles than the MK IIA (medium size – 73.5/73) and a shorter heat tube (138mm), but it is a touch lighter (1,430g compared to 1,445g). A slight change is the finish, now a matt grey with white Spin decals.
Spin Spitfire MK 1
The MK I here is built with Campagnolo Veloce groupset, Rotor Q-Rings (50-36T) and the same Schwalbe and Fizik tyres as the MK IIA. Wheels come in the shape of Spin’s new carbon Supersonic SSC50s. Complete builds start from £2,099; the build here is set at £2,690, with a premium on the wheelset. For this price it would come with the alloy Speed Metal 30mm.
