OK it's a TREK 460 I scraped the paint off..... to be certain now up.
Tough Crowd here

Oh and a new saddle

Nice bike, but are you sure it's a 1984 610? I bought one of those new, and it did not have dual water bottle mounts, and the fork looks different. Yours has obviously been repainted, but with that low lighting I can't see much detail.

I think it was 85 when the went to mostly braze-on shifter bosses, and I also think 84 was the last year the 610 was produced then they replaced it with the 600 in 85.

I think you're right about the shifters, but those are clamp-on not braze-on. So this bike is not later than 1984.

I wonder what the S/N is?

Here is today's Pic.

Shimano SL-A400, Light Action - non-index it was NIB

I started with just a frame I found a and bought a complete Shimano 105 group.

Wheels update SunTour Cyclone hub Mavic Open 4CD Rim for the rear and Suntour Sprint Hubed wheel unKnown Wheel for the Front Both 36 Spoke
OR 27" Shimano 105 hubs with a UG Cassette I think the 27" will take it over the height so probably the Malliards
The color of the Bike is Identical to my 1984 Trek 420L
I am not sure what the serial number is I thought I wrote it down

trek 460
serial confirmed
