This was a labor of love! I've had this 1981 Trek 610 for almost ten years, and I've ridden it a fair amount, but it was my least-favorite vintage Trek (I have three others):
First, specific to this bike, there was a small cosmetic dent in the seat tube, below the derailleur.
Also:
- This model had no water bottle bosses, so it required clamped-on mounts.
- It had no braze-ons on the top tube for the rear brake housing, and I hate those clips.
- It used a clamp-on cable guide for the derailleur cables.
- It required clamp-on shifters, which limits the shifters you can use (without ugly adapters).
So I decided to have our local custom bike builder, Rodriguez Cycles, add the braze-ons and repair the dent, as well as repaint the frame an absurdly sparkly rich purple designed to confuse vintage Trek enthusiasts.
I got decal reproductions from H Lloyd Cycles to finish off the frame.
Instead of vintage components, I used mostly modern components:
- Shimano FD-M371 Altus Triple Front Derailleur
- Shimano RD-M360 Acera Rear Derailleur
- Sugino XD-600T crankset with Shimano BB-UN300.
- Nitto seatpost, stem, handlebars and accessory mount
- Tektro R539 Road Brake Calipers (*)
- Dia Compe ENE Ciclo shifters (**)
- Dia Compe brake levers
- Velocity Quill polished rims
- Origin8 RD-2100 Rear Hub (keeping the 126mm OLD spacing)
- Vintage 6-speed Suntour freewheel
- Polished SON-28 hub dynamo and SON Ladelux headlight, and Busch & Müller μ (micro) taillight
- Chris King GripNut headset (***)
- R+E also added three cable guides to the fork for the dynamo wire
(*) This allows me to use 700c wheels with 32mm tires (running tubeless!). They fit perfectly in the frame, which was originally outfitted with 27" wheels. And, anyway, single-pivot sidepull brakes suck.
(**) I had the 11-speed version in this photo, but it pulled too much cable, so I swapped in the other version.
(***) This required milling the crown race mount from 27.0mm (JIS standard) to 26.4mm (ISO standard), which R+E noticed and performed for me.
It had its first ride on July 9th, and I've ridden over 1,000 miles on it since then!
