Nigel Dean 653 repair and build

[chrisrhayes]

Anyone know anything about Nigel Dean road bikes? I don't know much to be honest.

A friend has given me his 653 racing frame, which had some damage to the down tube (looks like corrosion may have weakened it), but the dura-ace fitted bike was used in competition a decade or more back:

What I didn't realise before I started this project, was that 653 road frames are 531pro main tubes (ie thin 531C) and then 753 stays, and were built that way partially due to Eddy Merckx request to have something more compliant over cobbles and such like (hence the very thin tubing in the main triangle).

Anyway, here's the frame and forks last week before repair at Argos Cycles, Bristol, where it is now.

It's coming out with a new Reynolds 725 Down tube and will be orange in colour. I'll keep you posted.

It's to replace my Concorde singlespeed which died in a nasty accident (myself and a curb).

I did a bit of digging a while back when I had a Nigel Dean and there was not a lot of info except that he was a pro rider turned builder. He had a shop in St albans (I think) and made some nice machines. When he decided to leave The staff continued to run the business for a time.

Good luck with the build, should be a corker.

Cheers

That's more info than I had, thanks. Yes, I'm looking forward to it, I'll put the photos up here sometime in January.

I think Argos are v busy due to the number of steel frames they are getting in for repair/painting.

throw it away
If the top tube has rusted away that badly from the inside out there will be nothing left of the other tubes internally either.
you can buy perfectly good frames for less than the price of an Argos respray

Too late, if it goes again I might, but if it works, it'll be worth it for sure.

The other tubes seemed ok internally. Seeing as though I'm not the lightest, it's either going to last a lifetime, or about a week.

Ah the beauty of brazed steel! You can sweat the braze (or silver solder depending on how it was built) out and replace the tubes.

It's nice to know what the mix of tubes is and why they were selected. It'll build up into a gorgeous frame!

To stop it happening again I use Waxoyl in my steel frames. You can get it in an aerosol from Halfords. Like the name suggests it's a waxy oil that doesn't come pouring out, squirt a good dose in all the available holes, bottle bosses, all the tubes, forks etc, it'll stop them rusting through. Just don't have the frame powder coated/stove enamelled after you've done it. The oil and heat will not go together well!

well I hope it doesn't cost too much to ressurect it. I am very attached to my steel framesets so I can dig where you're at. I've still got the first frame I braized together ,an old broken Carlton .

so what happened Chris ? did they manage to save the frame ?

653 was 653 main tubes, 753 stays and 531 forks. The different numbers mean a different steel. I doubt Merckx had any connection with the introduction of 653 in about 1987 as he had retired about ten years before, and the "Eddy Merckx" frames made at his factory used Columbus tubing.

Riding again

Sorry yes been away. It's done, and initial photos are here:

Yes I used a bit of waxoyl where I could get it, and I've left a small drain hole in the cinelli bottom bracket (where the screw goes in to hold the cable guide).

Downtube replaced with a 725 which probably stops the front end being *too* flexi (although it's noticably more compliant than the Concorde it replaces - I just hope it has the longevity). Which leaves the 753 rear end, and 531 pro top, head and seat tubes.

It's back in service now, just need some new handlebar tape and decent tyres.

First opinions: I need a higher gear as it gets to speed very quickly
Toe rubbing on sharp corners
No space for anything bigger than 26mm rubber

It reminds me of a time trialing frame made of Ishiwata 015 tubing (which was stupid light - coke can light), that broke. I hope this doesn't.
