Nice wheels but have been incorrectly labelled with Mavic 'Super Champion' rims. Super Champion was a manufacturer of rims in its own right and this is the wood version of their 'Competition' model. I doubt that Mavic ever produced wooden rims. The more popular models for Super Champion were the 'Medaille D' Or' and the 'Arc en Ciel', in aluminium of course, and they were later taken over by Wolber, possibly in the eighties. A notable manufacturer of wooden rims now is Cerchio Ghisallo of Italy, who also make a wooden framed bike.
Although modern riders can tend to be suspicious of the application of wood for a safety critical item such as a rim, wood is surprisingly suited to the stresses imposed on a rim and arguably combines surprising resilience along with a more compliant ride. Added to that you have the natural beauty of varnished wood which will complement any stunning paint job!

These look incredibly dangerous to me. They appear poorly engineered to me with the torsional moments created by braking acting laterally against the clamping forces of a single screw, plus the odds of one of the brackets coming loose are multiplied by four times. Anyone who has had even a computer sensor go into a wheel will know how dangerous it can potentially be. I would hope that these are bought as museum pieces only!!!

Back in the late 80's there was far less globalisation and if you wanted a top frame you would go to the local bike shop and a bespoke frame would be ordered from the local frame builder. And the same LBS would supply all the top end components to go with it. So it would have been the 'pinnacle' of bike shops amongst the local cycling fraternity, but probably would have been on par with the best of the rest in the UK also.
Hope this explains.

I have a Ridge Racing Low Profile frame from Columbus Cromor for sale. Ridge Racing was a high end specialist bike shop on the Holdenhurst Road in Bournemouth in the eighties and nineties and was regarded as the pinnacle of bike shops at the time.
The frame is particularly unusual because of the curved top tube and the seat stays joining the seat tube ¾’s along its length as you rarely get these two features together. It is built for a 650C front wheel and 700C rear wheel. The rear brake cable is internally routed through the top tube and the frame is drilled for allen key fittings on the brakes . It looks like a Cinelli Aero fork crown and has braze on fittings for the gear levers. No braze-on for the front mech so this will be clamp on. Water bottle bosses to the down tube only.
It has a 56cm centre to top seat tube and 54cm centre to centre top tube and has 126mm rear dropouts, which is suitable for anything up to seven speeds. It will fit anyone of medium height with average leg length ie.31” to 33” and with adjustment on the seatpost and handlebar stem will suit many people either side of those dimensions.
The paint finish is a sky blue with flame effect overspray on the top tube, ‘RIDGE RACING’ stickers to the seat and down tube and interesting silouhette of the rear end of a bike to the ‘RR’ on the head tube. It also has the Columbus Cromor stickers to the frame and fork blades and some ‘Campagnolo’ stickers.
It has the usual marks you would expect from a frame which is 20 years old. These are mainly on the back of the fork blades and there is one to the top end of the down tube. It has no dings or dents and is structurally sound. The one lug for the seatpost clamp has been bent in a little but still works fine.
Can send detailed photo’s on request. Now on eBay.

Hi everyone,
I have a partial Campagnolo Athena groupset in the rare graphite finish from around 1990. Buyers from abroad are welcome. Bank transfer is preferred but I will also take cheque or PayPal.
Campagnolo Athena Chainset(Graphite finish) – 170mm length with 52/42 rings. Rings have little wear but there is oxidisation and flaking of the finish to the one edge of the left hand crank.
Campagnolo Athena Monoplaner brake calipers(Graphite finish) – Original brake blocks and the adjusters turn freely. There is a small amount of rust to the steel hardware and appears to be some oxidisation to the arms but no flaking of the finish.
Campagnolo Athena brake levers(Graphite finish) – These are in excellent condition. No marks or road rash on the levers and the hoods still pliable and have no marks or cuts that I can find. Very nice.
Campagnolo Athena front and rear derailleur(Graphite finish) – Very nice condition overall . There is no road rash except a tiny mark and none of the chain rub on the cages you get when the chain unships. Braze on front derailleur has virtually no chain rub.
As far as I am aware this is a complete groupset apart from the gear levers.
Can send detailed photo’s on request. For the set I am asking £275.

Looks to me like he has knocked this up from afew spare components out of his garage. On the headset he has a Dura Ace lower race and Campag upper race! Looks dangerous too - no brakes, disc front and no bar ends!

'GRAB YOUR SELF A BARGAIN'
This guy still has not realised that there is no such thing as 'Columbus 531'. I asked a couple of weeks ago what grade of Columbus it is and he added an out of focus picture of the tubing sticker. Starting price is too ambitious.

^ I think a lot of us were :-)
It's probably late 60s or early 70s. You can get a better idea from the frame number on the BB shell. Vintage Campag Nuovo or Super Record, by the way.
Or Royce and keep it BritishRoyce is great British engineering, but was a bit later as they started in 1980 so would not be contemporaneous to the frame. But that is assuming you want to keep it period correct. Otherwise go for it!
Nice buy by the way.

Has this been posted yet? Columbus Air Aende Lo Pro (if the advert is honest, not sure how to tell...)
The frame looks more like Tange than Columbus Air to me. For me the clues are the clamp arrangement for the seatpost as this uses a screw from the back, whereas the Columbus Air used the more traditional clamp bolt arrangement with the clamp lugs brazed to the lug and then the split machined.
Also a Columbus Air bottom bracket has the Columbus 'Dove' emblem and the manufacturers name clearly marked to the underside. Surely he would have photographed and uploaded such a distinctive feature? I have a couple of pictures of these in my archives but have not been able to upload them.
I also believe that Columbus Air required a dedicated Columbus seatpost which was clearly marked and this machine does not appear to have the correct seatpost.

I have a Telfer Lo-Pro frameset which I am trying to build up into a complete machine. It is clearly a 650C front but I have put a 650C wheel in the rear which is clearly too small, and then replaced it with a 700C wheel, which fits but with the smallest of clearance i.e. a couple of millimetres.
I know that 27" was a generic size which bore little relation to the actual size as tubulars are generally more accurately described as 28"(700C). So are 27"(675C equivalent) rims and tyres available which will fit my Telfer?

Use a quality 1/8th chain such as KMC, as they will withstand the rigours of spinning the pedals on a descent and fit lockrings to the sprockets for the same reason. Otherwise the sprocket is likely to unscrew itself. If you have a flip-flop hub then you can fit a 15 tooth and 16 tooth sprocket and then see which is better suited to your style of riding by simply turning the wheel around.

The most interesting feature of this machine for a fixie rider are the removable rear dropouts. Buy a pair of track ends, cut off the lugs that insert into the chain and rear stays, mark out and drill accurately and then bolt them on using socket head screws. There is no need to replicate the adjustable countersunk slots of the originals and ordinary socket head screws would give a better joint engineering wise. Might be best to get a professionl engineer or even hobbyist engineer with a milling machine to get a really good conversion, but other than that it is the best donor frame I have seen to date. Would consider itself myself but it is too big for me.
But do not forget to keep the originals rear drop outs to convert back to original format.

These Campag brakes I believe are Super Record and are in good clean condition having just been serviced. They are the nut fixing type and hence are more likely to be for 70's/early 80's machines although it depends entirely on the drillings in the frame you intend to fix them too. These will be a nice addition to your retro ride. Price £80.00.
Should you require additional info do not hesitate to ask.

I am a qualified Carpenter and Design Engineer and have in the past work on a number of equipments and structures where I had to conduct stress analysis. As indicated in my previous contribution the two elements which generally dictate the overall strength of a component are the ultimate tensile strength of the material and the Moment of inertia of the section which is roughly defined as the resistance to deformation as a result of its shape and form.
There are other factors which come into play such as the direction of the loading as wood is more effective in compression whereas steel and aluminium are more effective in tensile. But the Ultimate tensile strength(UTS) and the Moment of Inertia(MoI) are the two keys elements to be considered in any stress calcs.
To say that 'laminated solid wood handlebars would massively out-strength hollow aluminium bars' is guessing.

Love the paint job on this classic track bike. Many of the Carltons from that era had a similar paint job with translucent colours on a full chrome but the simplicity of the tri colour bands on the headset and seat tube gives an iconic bike an equally iconic paint job. For me this is classic design.
I have a Basso 'Loto' in the same colours and the paint job is just superb. In the late eighties the 'Loto' built from SLX was the top of the Basso range. It looks to me like an identical frame although it does not have the distinctive 'Loto' logo. The price of £230 I thought was fair particularly with the unusual chromed front lugs, so the sale price of £190 was a bit of a bargain. Certainly a lot of frame for the money.
Apparently Basso's are renowned for awesome paint finishes, because they have invested heavily in the finishing side of the business and have built an excellent reputation for that. This is in addition to building great frames too.
