They are both 2009 Knight Proformer frame sets. There were only 30 made by Knight in two batches of 15.
They came bare metal with Spanish BB, 1 1/8th Integrated headset and rear 990 mounts.

The blue one was from the first batch and has the cable guide on the left front fork.
It has the 990 mounts and rear cable guides removed and a 901 caliper fitted, so is unique!
Makes it look more Old School.
Building them wasn't that easy as they are retro styling but new school geometry and fittings.
I've always loved the GT blue so that was a no brainer.
The pink one was done to be in your face
The colour changes as you walk around it orange/pink/orange.
I guess they are marmite but always turn heads
