That looks like a real nice cherry red metallic finish mate so whats it like since you'd upgraded the parts and does it feel any lighter and tbh it doesn't really look that big ..
It's a bit flexy and I think it's had a less than salubrious past, it doesn't have a frame number and I suspect that the grey of the regular frame was removed as was the head badge....The decals are not original either.....
It's a decent bike, the loooong head tube actually brings the bars up to a decent position and with the upgrades it's prob not hugely better / lighter but I prefer it.
I expect the bb to seperate from the Downtube or stays at some point, the seat post is wedged but at just the perfect height and as a baby / kiddie transporter it's perfect
I once beat 19 out of 26 fast German Enduro boys down the local double black on it, but for catching the rest too near the fast bits at the end it would have been more, I think they were surprised and there was a lot of pointing at the trail head....
