The first run out on a fairly recent acquisition ~ a Trek 810 Singletrack, from around the turn of the century (that still doesn't sound right)!
As with my Univega I completely stripped it down right away (been watching too many YouTube videos) and serviced / fettled as necessary. It's had a new bottom bracket and brake blocks but the rest seems OK, even the headset was in decent condition. The frame is tatty and battle scarred and the front & rear mechs looked like they had come off a bike from the bottom of a canal, but an overnight soak in turpentine and a scrub sorted them. A bit of WD40 sorted the sticking gear shifters and I didn't even bother changing the cables as it shifts well enough, though the lack of intermediate stops for the front mech causes a bit of chain rub at the extreme ends of the block in some gears. The seat is decidedly secondhand so I may replace it, but it's OK for what I'll be using it for, and original. Even the ski ramp upswept stem doesn't seem as awkward as it looks. It's a heavy old lump mind, but was still enjoyable on it's first outing, maybe it's the (relative) old fashioned-ness of this type of bike that rekindles memories of being a kid, discovering bikes and how easy it was to travel decent distances with ease.
