Last year when I was searching for parts donors I found a expensive-feeling Giant hybrid with Exage 400 parts. I finally only ever used the RD and took the rest to the coop. It was a large sized frame that really well demonstrated how a hybrid is different than a road bike - especially the enormously long top tube and big tire clearances which gives long chain stays and avoids toe clip overlap. It was also a nice example of a high quality mass production welded frame, with unbranded DB tubing, double rear eyelets, midblade fork mounts, not too heavy. I guess at the time, it was though that the marketing category would replace traditional drop bar touring bikes. I hope it got another life and made someone a nice bike.

Good eyes,

I am at work now and will post details and photos latter.

I have rented the 2 br upper level of my duplex since June, on AirBnB since July. It has stayed full since then, February being the first vacant month. Only the June renter used the free Bianchi hybrid because the family came in one SUV and trailer from Austin, with only room for kiddie bikes. One AirBnB renter brought his own bike up from Baltimore. The balance walk or drive, even though biking here is breeze, so I don't think it is a huge selling point.

I just converted a Fuji Royale to Northroads handlebars and a Brooks B-72. Comfortable rider, but the bike seems skittish compared to my hybrids. It may be the cheap 27" Kenda knobbies though. I plan to replace them by spring, but for winter, the rough tread is handy. Fenders pending too.

The bracket is a hack of the Minoura bike bottle holder Bottle Cage-Adapter Saddle.aluminum with a piece of aluminum channel from store

and the tail light is a Busch & Müller Toplight Line Brake Plus from Longleaf Bicycles

Yes, but I can't recite the specs from memory. Should be findable easily enough. The 510 dates from the early days when Trek sold framesets and the bike kits to make them complete bicycles. The 510 was the Ishiwata tubing in sport-touring geometry. The 530 was the same tubing (probably exactly the same main triangle, not sure) with shorter stays and a different fork for racing geometry. The 520 came later as a complete bike and while the earlier ones were sport-touring they quickly evolved into touring-specific bikes with cantilevers, braze-ons and geometry to match, such as much longer chainstays. My wife had an early taupe 520 that still used caliper brakes and had an SR triple crank that was a Stronglight 99 copy, but the bike overall was more sporty looking than tour-y.
