Wouldn't be hard to extend the shape along the chain stays and clamp it on to stop that?
The best anti theft device is a handlebar that rotates when the brake is pulled :)
From the photo on the yellow frame it looks like they've got a screw/bolt/dowel to prevent rotation - but I like the idea of making something a bit more substantial to eithet clamp around the whole dropout, or onto the chainstay....
I developed a new anti-theft device yesterday morning, when you after a brief skid the wheels start moving again... then you hear the 'ting' of lockring on axle and adopt the " traffic free path"
Bit of a bugger cos it was a very beautiful hub....

mmm death-trap porn

^^ Sounds like a good scheme - the old Archer GP course perhaps, or the 1948 Olympic route round Windsor Park......
^ No problem - agreed - especially on examples like this where decent non-period kit has been fitted to bikes.
There's a general aura around period bikes created by their untouchability - if something's been in the package for the last 50 years on a shelf in an italian bike shop, how dare you ride with it. In the last year I've sold off all the NOS vintage kit in my shed when I discovered I was too scared to use it.
Bikes are there to be ridden and if you start worrying that you'll damage your investment by putting in the miles then you need to ask yourself a few questions!!
My brother and I still ride this 30's track bike on the road and track and gain a great deal of enjoyment from it - no idea what it's worth and don't really care tbh... there's a lot of fun to be had on old kit and it's a shame when economics get in the way of it - which is kind of what this thread is about...

Yeah it's round.
An oval chainring and a single speed drivetrain would surely be a terrible, terrible idea would it not?Don't know about oval, but I've ridden Biopace fixed: It worked
There are roughly 50% of the teeth engaged with the chain at any point it's only the radius from the BB axle that varies.So it's not a terrrible idea, just a bit annoying. There's a slight variation in tension as the chain angle alters to accomodate the chaging radius: Smooth pedalling was one of the reasons I started riding fixed in the first place

Brake cables, bottle cage, chain and front mech arrived today, not quite finished installing them but it's starting to look good (pictures to follow).
The Simplex AV223 "Prestige Criterium" front mech (courtesy of MrWolf69) is extraordinary, rather than the 4-bar linkage design we all know and love, there's a cable operated linear actuator (piston) that drives the cage... I've never seen anything like it

Managed another ride at the weekend, 70miles down to Brighton(3.5h) and fitting in extra climbs on my commute. I'm becoming increasingly fixated with cake and living in a world of fear and (self)loathing - so it's all going to plan!! I feel like a roadie again (except now due to the state of my body I have all the pain and none of the form I may have had in a previous life). Due to family commtiments it doesn't look like I'm going to get any proper big rides in before October so it'll be extended commutes and riding for survival on the day.
I'm considering adding a 3rd Work Package to this project - the sartorial.
I suspect my normal cycling garb (carhardts, merino t-shirt and adidas merckx) won't really cut it with the level of commitment I'm expecting from the fellow riders! check out this specimen.

Bring on the wool -

Inexplicable slave fads from Japan are amazing though - one of my favouritse is the chopped-but-not-flopped hillclimber drops - giving you the worst of all possible worlds in the name of obsucre slavery.
(Apologies if this gets some youth questing for more "glossy photos of....." this image was purely to illustrate a technical point and I couldn't easily find any others!) -

In my experience, contacting the bigger companies and asking them about their own history is rarely a success! Sometimes it's better to speak to collectors and enthusiasts.
Seat-lug & fork crown are certainly Cinelli-like so it may be worth contacting the guy who runs the Cinelli-only blog. Another good place to try would be the Classic Rendezvous forum, I think they'd be quite interested in it and much more likely to provide a quick and helpful response -


Toeclips arrived today: quite a lucky break really. Ebay listinghttp://rover.ebay.com/roverimp/1/710-53481-19255-0/1?pub=5574889051&toolid=10001&campid=5336525415&mpt=[CACHEBUSTER]http://rover.ebay.com/roverimp/1/710-53481-19255-0/1?ff3=2&pub=5574889051&toolid=10001&campid=5336525415&item=110943341172&mpt=[CACHEBUSTER] barely mentioned straps but when they arrived they're Alfredo Binda.
Galli clips on Zeus pedals - All I need is a gipiemme chainset for a complete "poormans-campag" suite!

Just had a thought: with a 3-pin Solida chainset what's the chance the pedal thread's are going to be 14x1.25mm rather than 9/16 x 20tpi?
Update: Managed to remove the big steel rat-traps (fitted to the donor BSA) - and the Zeus track pedals fit fine, quite a relief.
Frame seems completely full of iron filings, rotating the frame fills the bottom bracket shell leaving BB feeling graunchy.
I had to clean and re-fit the bottom bracket twice, and ended up doing 4 hail mary's (strip - clean - regrease - re-fit) before the headset would run cleanly.
Never seen this before and hope I won't see it again: I'd recommend blowing a frame through with compressed air and possibly using aerosol waxoil or weigle framesaver to prevent this.
