Katakura Silk Gloire - finished!

By popular request... well, a couple of people at least. And before I start, I'd like to say a big THANK YOU to all the people who made suggestions about how to clean the rust!

We stripped the bike down to the frame, cleaned all the rusted parts and rust stains on the frame with oxalic acid, checked all the bearings and reassembled.

The bottom bracket spindle had very slight pitting and we were going to re-use it until I remembered I had a Tange spindle of the same size and design (with crank nuts instead of bolts) left over from when I fitted a Campag spindle to my 1979 Dawes Atlantis, so I donated it to the Gloire.

We replaced all the ball bearings except those in the rear hub, which were fine. Apart from the BB spindle all bearing surfaces were excellent.

The rear brake caliper mounting bolt sheered when I was dismantling it to remove the rusty spring. For the time being we've replaced it with a Weinmann rear caliper, also from my Dawes. We might look for a usable replacement bolt. The Weinmann bolt was too thick.

The wheels came up very nicely with wire wool and Autosol. Luckily, the spokes are Hoshi stainless steel so are clean. The back wheel was a little off true so we had it straightened by the LBS and were pleased that the nipples turned freely. We simply brushed the rusty spoke eyelets with a brass brush and then oiled them to prevent rust returning. Should be enough as the new owner of the bike won't be riding in the rain. Likewise all the cleaned up chrome parts.

The new owner decided on Vittoria tubulars with a yellow line and yellow handlebar tape to match. I think it looks great except the gel/cork tape looks a bit heavy on such a small bike - can't be helped. We fitted the tubulars with Miyata rim tape, which was really easy to use.

The owner wants to change the seat for a Brooks B17 S except it seems they are only available in Black or Honey and she wants a dark brown saddle. I think the Honey might go well with the yellow...

The frame has been treated with Waxoyl, the UK version of Framesaver. Probably not really necessary for all but the seat and chain stays, which had a bit of flaking on the inside of the drain holes.

New cables throughout. Haven't been able to find brake lever hoods which will fit so they are bare. In any case, she might decide to change the handlebars to North Road type. I thought she would do that straight away but she said she wanted to try the drops first.

This Gloire retailed for 69,000 back in 1983. The top of the range Katakura Silk racer retailed for 223.200. This Gloire was the 6th in a range of 9, pricewise.

There is an album of photos of the Gloire at:
