Stem is a beautifully made 110/120mm (non branded that i can find) a-head style. Yes i also am surprised has its an almost perfect Ti flagship model. Plus theres no rusty seat tube on it
Seem to remember this era of Raleigh coming with Panaracer Timbuc2. Might be imagining it though 🤔 XC-Pro hubs had cartridge bearings with only a seal on 1 side for the Grease Gaurd system to work. Check for a grease port on the hub and if you have one inject some grease into it. Might cure that...
