Been riding for 8 months a 160mm Enduro Sworks carbon before this Spitfire V2.
So far had two half day ride sessions on it. I had also rode before the Spitfire earlier older version.
Spitfire rides like an awesome trail bike with great pedalling capability even with such a slack head angle that mostly found on All Mountain bikes. Climbing is very good and descent is fast and very linear. Though Enduro gives a more plusher and stable on descent ride , Spitfire is as good. Only its 140mm travel and aluminium frame may not give as fluid ride as a carbon 160mm travel bike, Spitfire make up with its fast ride in both ascend and descend sections. It just want you to take it fast as you can.
Having a 650 wheels certainly make that task easier. Bike controls on tight trail sections are still good too. Will update upon more rides in 6 months time..
