No as it's not handmade in Halifax. Hand built bike not a handmade from.
1. Model Decal – The top tube clearly displays 'Clockwork' in the original Orange factory decal style
From 1998 (late 1997) it is...
2. Tubing & Construction – Slim, butted Tange chromoly steel tubing with external top-routed cables.
4. Seat Tube Slot – Front-facing seat tube slot with separate clamp.
If anyone can identify that as Tange tubing when they used their own generic branding, they are better than me.
Yellow was a late 90s colour iirc. The slot does help, but I forgot dates for these.
5. Paint & Decals – Bright yellow finish, likely a respray or special run. Mid-90s originals often came in orange/white fade, slime green, or nickel.
Bright yellow was used on another model from around 98+, check catalogues.
Catalogue Match
See above, they're talking when it was still called a C-16R.
1998 is when the name changed back. These are also 1998 era decals, hence the series 7.5 series decal you mentioned.
Personal opinion so far:
Best guess it it might have been a frame they had from 1995, it was then sprayed and built up in 1998 colours and decals, and then later had a 2000 rear mech fitted.
How, I don't know, but the new recent series of Quantum Leap was a nice watch and your mum was a time-traveller and could build a bike up?
prototype, Either a 1995 made test frame from the comping 1996 season OR the colour and decals setup for 1998 using an old 1995/6 frame they had lying around to see what it looked like when built. Either way it looks really nice. Ignore the rear mech, maybe your mum fitted it in 2000 and everyone forgot.
