I bought my RRS back in 1990 for £220 from the lbs in Letchworth, pretty much identical to that pictured as far I can see. Sports tourer weighing in at around 22lb I seem to remember.
Jet black with the black weinmann(?) rims, can't remember the hubs but they were both QR. Michelin Select tyres, 6 speed 13-24 block, Suntour accushift DT shifters, Black chainset (could have been a Sakae) with steel 52/42 rings, black aero Weinmann levers and black tape. Can't remember what the derailleurs were tbh.
Also had very nice Olimpic XXII ally quill pedals and some christophe copy cat toe-clips by a now defunct Spanish Motorbike company (I forget the name)
Honestly it was most comfortable bike I've ever owned & my first proper outing on it was the first leg of my tour of Northern France doing approx 700 miles in 10 days in 90+F every day (bagged a TdF final day down the Champs Elysee too
I probably did 20-25,000 miles on it changing only the tyres, tubes and the saddle (for a LOOK la vie claire job) then sold it on after not using it for a few years.
So from my personal experience I'd say buy one
