Perhaps?, or reminscences?
I will still hold the RC100 up, as a symbol of radical thinking (of the era)
Externally butted tubing; easier to mill/pare the weight?
The chain-stays encouraged mud to sit though, on claggy courses/rides
If you asked, at the time, they would make you a custom frame
The split fork-crown; with individually replaceable fork-legs (also interchangeable with the later RC35 suspension forks)
The head-set; basically an upside down version of what we have today (saved -at the time- carrying big headset spanners, just a 10mm spanner & 5mm allen-key)
The only downside was the set stem length/rise, but when you ordered a new bike, they'd make the stem as you wanted
Bullseye crank-arms; exactly what Shimano do today, but the Bullseye wasn't as secure, as the only lateral 'stop' was a tiny shaped 'key', it'd have been far better with a cap, that screwed into an internally threaded crank
Hydraulic brakes; good, powerful, but...... they still had the clearance issues, & wouldn't accept an inflated tyre (I only used 1.5" tyres on mine & they wouldn't go past
The guides were plastic (& agreed, yes, 'sacrificial', but left water-ingress points on the top-tube
Grease-nipples; on bottom-bracket & head-tube, which accepted a normal -car- grease-gun (& later on, they were built into their own hubs, when they started producing them)
I know it was common practice many years ago, & I remember having an oiling-hole on a old road-bike, when I was young.
Not my bike, in the photos, below, just used to illustrate
