How to lock a Pashley Guvnor?

A small challenge, but while squinting at the Guvnor, a thought occurred. The seat stay is bolted on with regular nuts at the top and bottom. Wouldn't this make any U-lock passed through the rear triangle almost useless? A quick twist with a regular spanner and the wheel goes free.

The only way round I can see is to lock the rear wheel to the main frame, but if I'm doing that to the front wheel as well, then it seems I'd need a third U-lock to go round the proverbial immovable object. Pashley's relaxed frame doesn't allow you to pass a U-lock through a wheel, the main frame, and an object all at once, everything is too far apart.

One other potential complication, the Evo mini I'd normally use is too small to lock the front wheel to the frame. The Fahg mini fits perfectly, but seems overkill for the job. Plus, if you need to carry three locks, weight is a premium. Perhaps cutting the rubber off would help, but shiny things don't like bare metal. And I'm not going to use cables.

Maybe I'm missing something obvious. Any ideas?

Here's a picture I borrowed, to illustrate:

(a larger version if you need it) - credit to the original poster, who ever you are.

Is this a serious question?

*amazed*

I'm not sure! The answer must be so obvious, but I can't think strait.

Secure the bolts? Pitlocks?

I did say "small" challenge.

Lobotomy perhaps?

**Locks That Work **

Motrax Disclock Large [19mm] (Badly named, because it is a U-Lock) £22.49

GRP Superdeals U-Lock [18mm] () £14.50 (this is the lock I own)

Either through the rear wheel and the main frame. Any other lock you choose for the front wheel to main frame.

And the immovable object? That's the three lock problem I was talking about.

I have the Fahg mini for rear-to-frame, and the KryptoLok Series 2 mini will fit the front, keep the weight down. Already at 3kg. Surely the beefiest lock should go to the object? That takes me to 5kg. Is that fine?

Right tools for the right job. Your locks are the wrong ones for a bike with such large clearances.

2 locks is all you need. Locks (examples) highlighted above.

EDIT:
Though you clearly own the best lock, its not the best lock for this particular situation.
Fahg Mini is not appropriate for this bike IMO.

Ah, I'd taken the "narrow shackle" security advice to heart.

I'll go try on the wider, longer ones. My usual problem comes up though, I'll need to comply with insurance .. already paid for a year. Limits my choice of second lock (or whichever goes round the object).

I know you don't recommend the Sheldon method in any case, so really my question about the rear triangle was a red herring. Thanks for putting me on the strait and narrow (or wide, as the case may be).

The Sheldon Method is fine, but not for very high crime areas with professional bike thieves.

ie. many regions in London.

Ah yes, I left that caveat implicit; "in any case" should read "in my case" .. I'll be locking up in just those areas.

Perhaps I shouldn't fret so much, secure my wheels at least, and rely on insurance for the rest. New for old and no deductions for wear and tear, after a few years I'd almost thank the tea leaf.

... Oh, and might you have the dimensions of the GRP to hand?

...or when your rear triangle comes apart, rendering the sheldon method wank. undo seat stays, pop out rear wheel, take off with frame and front wheel.

why are the seat stays removable?!

Indeed, that was my point. Something about "tradition". No Sheldon method for me, even in the quieter provinces.

Can't find my tape measure at the moment. I'll report back tomorrow.

Thanks GA2G, but no rush, I can't pop over to Peckham for a few weeks.

The Sheldon method is fucking stupid. It's the only thing he was ever really wrong about bike-wise, thinking that thieves wouldn't just cut your wheel in two and nick another one off another bike. Of course he lived in Boston, where all the crime was taken care of by Spenser and Hawk

Can we get these guys? Angel needs them.

Having both a GRP lock and tape measure to hand I can tell you that the internal dimensions are 11.5cm wide, 26cm long (21.5 to start of curve).

Cheers Savvy for saving me the effort. However, A.E.Wilson sell 2 GRPS U-Locks. The one I have is the one in the photo, with the square-tubed bar. They also do one with a more traditional round-tubed bar. Is yours the square or round one. The square one appeared to be just a bit longer, but also of thicker bar diameter....18mm vs 16mm?

The Sheldon method is fucking stupid.

I will destroy you for this statement.

He is are genius.

Who's taking bets? I'm puttin a tenner on Nhatt.

If your main concern is weight, isn't this i pretty heavy?
I worked in a bike shop for a bit and built a couple of Pashley's, from what i remember they weighed a ton?

GA2G: I was measuring the square-bar version... :-)

old horrible design from the 50's, no surprise there!

in all honestly, I somewhat doubt thieves realise that they can take off the rear stay by a few turn of an allen keys.

The Sheldon method works great on my 1948 Clubman, which has similarly large clearances.
It's better to put more of the bike inside the shackle, of course, but seriously, just try cutting a steel wheel with a big tyre in half.

Thats the thing chris667, most modern rims are lightweight, and the strength comes from the shaped internal bridge, and tyre inflation. Old rims were heavy monstrosities, which would have any thief just walk on by. But faced with a lightweight race bike, with lightweight wheels, .....out comes the boltcropper, or battery powered angle grinder, and that wheel would be history. And the rest of the bike would be gone. Easier for a serious pro thief to steal another rear wheel from someone who felt a cable lock was good enough.
