Project 2108/A - 1984 Koga Miyata RoadWinner

Later this month mrs non-fixie and I may have the opportunity to participate in a C&V event for the first time in almost two years: Eroica Germania. Covid regulations are changing every week here in Europe, so nothing is certain, but I thought I'd at least prepare a couple of extra bikes, just in case.

Project 2108/A (project 2108/B will follow shortly) is a new bike for mrs non-fixie. Browsing through my archives I found a bike with a short enough top tube (women prefer/need shorter top tubes than men, I've found) that *could* work. A 1984 MY Koga-Miyata RoadWinner.

I took the bike apart yesterday, and cleaned up the frame, the bottom bracket and the headset today.

The frame, with a 50cm ST and a 52cm TT:



This model got an upgrade from the '83 version. Shimano 105 'Golden Arrow' was replaced by Shimano 600 EX 'Arabesque'. This particular machine was exceptionally dirty when I bought it, but the parts still seem to be in excellent shape. At least the bottom bracket and headset are:



Below is a pic from the 1984 catalog. I will be changing a few things, in order for it to work for my girl: a crank set that will take a smaller inner ring will replace the 130 BCD 600 EX, and the bike will be keeping the Shimano DEL-80 dual action levers it came with. They work well, and with mrs non-fixie's small hands and limited experience with drop bars I don't want her going down a steep incline without them.



More cleaning tomorrow. Lots of it.

I wish you luck with pulling off the Eroica event. You two will have nice bikes if it rolls!

Question, the seatpost on that one is colour coordinated with the frame, accessories. Was that a regular thing in Europe?

Thank you! We've actually registered for three events, to improve our odds. And we've got backup bikes.

Color coordination was maybe not really "a thing", but it looks rather spiffy, I think. I got the matching pump and toe straps as well.

I built up the bike to MVP level ...



... and mrs non-fixie took it for a shakedown ride today:



She couldn't find anything wrong with it, but she wasn't enthusiastic either. "It feels heavy", she said.

When we got home and I wheeled the bike inside, I noticed that the front brake was rubbing. And not just a little bit. I remembered it being a little loose and tightening it, but apparently I forgot to properly check the result.

Oops.

I resolved the brake rub issue, and today we went for a 60k ride. Mrs non-fixie liked the bike a whole lot better. So much, in fact, that she will most probably take this bike to Eroica Germania next week.

Today, she soared:

Nice! That is a few years older. 1980 or 1981, I believe. Came with the underrated Altus LT derailleurs and shifters. I like the Centeron mechanism on those.
