Every sale helps refurbish and donate bikes to those in need through Bicycles for Humanity Colorado. Each item has been professionally inspected, thoroughly cleaned, carefully refurbished, and is ready for immediate use.\u003c\/p\u003e\n\n\u003cp\u003eThe Trek 9500 STS (Suspension Track System) is a standout piece of 1990s full-suspension mountain bike history, featuring Trek's unique STS rear suspension design where the chainstay itself flexes through a proprietary elastomer\/coil shock unit — a clever, low-maintenance system that delivers genuine trail compliance without the complexity of a traditional pivoting linkage. The frame is built from carbon with Trek's distinctive OCLV-era tube shaping and features a gorgeous deep purple-to-forest green color-fade paint scheme that is iconic of Trek's mid-to-late 1990s lineup. The front derailleur braze-on mount, cantilever brake bosses, and threaded English bottom bracket make this a relatively straightforward vintage build. The rear shock unit appears to be a Risse Technology elastomer unit. The paint shows the honest patina of a used frame — scuffs along the STS chainstay, some scratches near the BB shell, and minor wear throughout — but decals remain largely intact and vibrant, and the frame appears structurally sound. A true collector's piece for the vintage MTB enthusiast or a genuinely rideable retro hardtail-adjacent build.\u003c\/p\u003e\n\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003ctr style=\"border-bottom:1px solid #e5e5e5;\"\u003e\n\u003ctd style=\"padding:8px 12px; font-weight:600;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;\"\u003eGood - Some Signs Of Use, Fully Functional And Ready To Install\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom:1px solid #e5e5e5;\"\u003e\n\u003ctd style=\"padding:8px 12px; font-weight:600;\"\u003eCondition Notes\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;\"\u003ePaint scuffs and scratches visible along the STS chainstay tube and near the bottom bracket shell.
