Thanks, they are both 109.5 and Italian threads of course. The new one is minus left hand 'cup' so I would use the one from the 7700. I read on Ebay that the 105 version was not compatible for some reason.

I have built many classics from the 50s/60s but just about to venture into a new era. I have a Colnago Master X-Light just over 10 years old and plan to fit 9-speed Dura Ace group set.

The chainset and bottom bracket will be Octalink. I have two bottom bracket units, one is a 7700 which is ideally matched but used. The other is an unused 6500.

Is the 6500 compatible with the 7700 cranks?

It's OK folks, I found the little critter making a run for it on his skateboard. Game on again but you may need guidance to find it.

L'Eroica Italy will be first Sunday in October as usual.

Is it not partly due to the back wheel being higher on a stand?

I asked if it was 25" as Dave Keeler rode similar track frame in Worlds at Milan in 50s - he always rode 25" and I wondered if he was the owner.

The stem would be the alloy spearpoint unless you could find the steel 531.

Chater-lea were all steel cottered although there were Stronglight alloy 49 cotterless at the time. They we used mainly with TA rings - single 1/2" and even inch-pitch.

Is it 25" by any chance?

Could have been Chater-Lea chainring and pedals, Fiamme sprints on Airlite Continentals or Harden hubs, Brooks Sprint or Swallow saddle, GB bars and stem also brake. There were other alternatives but this was the classic build.

You can ring them - most of the operators speak good English.

The striker forks need to go much closer to the sprockets. Nearly touching the big one. If you do set it up like this you have to make sure you shift to the small sprocket before taking out the wheel. This is one of the problems with Osgear hence the special Stallard ends where the wheel goes backwards to come out of the frame thus protecting the striker from damage, For this reason Osgears were popular as track bike conversions 'back in the day' when riders finally gave in and used gears for the first time - most people were using road/path frames with rear facing ends as they had been on fixed for years.

Needing to overshift is common. These gears were often used on very close-ratio blocks with one tooth difference. Should cope with a two-tooth difference but it helps if the ratio is even, eg 16-18-20.

You have to adjust the tension both ways every time you change gear - at least you are not juggling with a Paris/Roubaix changer and having to do the changes pedalling backwards!

^^^^^^^
In theory that must be so but if you have critical clearances, for example just room in the rear ends to move forward 1/4" then Sod's Law kicks in and it never quite works as it should. It is one of life's unsolved mysteries along with choosing axle length/bottom bracket shells for early classics.

Here you go then.

We (Patricia and I) have booked for Saturday, Monday and Tuesday. We are staying near the stadium and also near Steel Vintage Bikes Showroom in Berlin. Our first time for the Berlin 6 but went to Munich for about 5 years running. Also did Gent for a few years many years ago. Looking forward to seeing the big pacers.

We have a pair of Donohue 'power' forks which are undamaged. Bad news is that the column is for 48cm frame but it would be possible to get someone like Winston to fit a longer column. £15 picked up in Cambridge. Can send images if you pm your email.

Left - old one, Brookside looking towards Leys School
Right - new one, lets not have a big song and dance about it!

Anyone got this yet?

Just worked it out but will be getting the miles in tomorrow. Will try later if no one beats me to it.

It's taking RJB a long time to get home, maybe he stopped to pick some fruit on the way.

Any idea where Winston has gone, or what the name of his new company might be?

I think he is working in the same building as his brother Mario (Vaz).

A bit of Donohue history as requested, we bought a few of Paul's bikes in 1997/8 I think. They were amongst the first built in Reynolds Millennium tubing, Patricia had a 531 winter bike followed by a 653 close-clearance summer bike. I had a 531 winter followed by an 853 which was built in the same series as the Team Brite bikes but with Donohue stickers. The colour was known as Brite Red.

When Paul heard that I was thinking of a Colnago frame he offered the 853 built with a complete Dura Ace group set for the same price. It was a good deal so I took him up on it.

We got quite friendly with Paul and met him several times over the next few years, he was a really nice genuine man.

He explained that he was having to compete with imported bikes but wanted to keep the Donohue name for his own builds. Just at this time Cougar went 'bust' and Paul bought what was left of the company in order to sell imports under the name Cougar. He inherited several frames with the buy-out, built I think by Terry Dolan, he sold one to me for the cost of the paint job (with the correct Cougar stickers). From here on he sold his imports under the Cougar name.

He had a lucky escape when he was awarded the contract to build the bikes for the LInda MaCartney team which was being formed. The team pulled out of the deal and the contract (for what it worth) went to a foreign builder. The rest is history - the team set-up was in fact a scam and there was no money behind it so the bikes were never paid for and the team soon folded. Paul also built all of the Graham Weigh bikes at this time including the junior track bikes for Manchester, this is why he was able to build the small frame for Patricia just as she wanted it.

I'm not sure when Paul gave up the frame building but he was a highly regarded builder who assisted Reynolds with test builds of new tubing. Having got away from the bike scene he soon lost interest completely and doesn't respond the requests for information. He did however hand over his decal/transfers to H LLoyd Cycles which helps restorers.

Found it at last, thought it would be Regent Street but entrance to Highsett is now Tenison Avenue.
Left is old and right is new - we have got away from the station for this one:

Follow the DNA path until it turns sharp right away from the railway line. Ignore this right turn, you go straight on under the road bridge, follow path and TL at road onto cycle lane. In about 300 metres TL over the rail bridge (guided busway). When over the bridge TR at busway junction and follow path to station. Much better than the road route.

I see that Mario is still running the Maypole, some 30 years since I first went there!

And the route posted above seems to miss out the guided bus route on the final approach to the city centre. What I cannot for the life of me remember is how we got from the DNA path onto that new section of road that leads up to Addenbrookes - from there I remember we head west on a spur of guided busway and then right which takes us directly to the station. Did we just climb up the embankment and over the crash barrier?

Think he is open on Saturday 10am until 12noon

Does anyone know if Mario's workshop is open on Saturday's? I need to take something to him but canny do it in the week...

I don't think you can order vinyl for decals in RAL colours - presuming that's what you meant.

How did it look Amey? Did it look like it had a 27.2mm seatpost successfully installed, and a BB that fitted properly?

Did you know that H LLoyd cycles have some of the original decals?

I didn't strip exif so if you wanna be a party pooper you could find it, or you could just play the game.

First post outside classifieds and a picture of my first conversion build!

Give us a clue then.

Not Ainsworth/York Street play area.

Station yourself in the right place to get an image of it then.

Pretty sure that's on my way home...
