Managed to find an early Klein Attitude frame - regretfully without forks or MC-1 - but had reducers. So fitted period RC35 - nicely refurbed by Tim at ForkEnglish (until i find some Klein forks and bars), threw on some bits from the garage parts stash and Ebay to make an interesting lightweight 700c Fixed Wheel MTB to ride about until the trails are dry enough for the modern full susser ! Did the North Downs on Saturday - it rides really well - but a bit exciting on the jumps ! Any suggestions for parts to develop the build are welcome.
