Also away from the Raleigh USA catalog specs are the shifters, brake levers and grips. I never was a fan of Grip Shift and it seems that the original owner wasn't either as the SRT-500R shifters were replaced at purchase time with a pair of Shimano Deore XT ST-M737 combined shifters and brake levers. The stock Dia-Compe SS-7 brake levers were thus ditched, as were the ATI John Tomac grips (cut to fit with the SRT-500R) replaced with a pair of Ritchey True Grip WCS.
By contrast, the Tioga PowerStuds are OEM. As John Tomac's sponsor, Tioga also provided the Alchemy OS-NSS-AL stem, Alchemy headset, DL2000 handlebar and seatpost. The saddle is a Vetta SL one with manganese rails, manufactured in June of 1993.
Also standard are the Deore LX Hyperdrive-C BR-M560 brakes, stamped with Shimano date code RF/RG for the front/rear brakeset, thus translating to June/July of 1993 manufacturing date. Some fresh Shimano M System M70/T2 brake shoes have now taken place of the totally dry M System ones that came with the brakes.
The wheels are built with Mavic M231 rims, unknown double-butted 15g stainless spokes with gold alloy nipples and Deore XT HB-M737 (front) and FH-M737 (rear) Parallax hubs, both stamped with Shimano date code RI, so manufactured in September of 1993. The wheel shield and reflectors appear to be in immaculate condition so I opted to put them back in place once the wheels were thoroughly cleaned. The Psycho-K/S "butterscotch" tyres by John Tomac's sponsor Tioga are however totally dry and unrideable; I just put them back on the wheels to take pictures of the bike in original configuration . Feel free to advise "modern" butterscotch tyres.
