Any question answered...

Panama?

Was hoping for a suggestion in London's famous London.

Has Tredz stopped popping up that £5 discount? Wanting to buy some shit but it hasn't appeared yet.

Take the £5 hit and buy from somewhere reputable.

Did chuckle.

Want to change my Praxis cranks from 175 to 170. Have 175 on the bike at the moment. Do I need any special tools to switch the cranks?

This seems to indicate that I only need a 8mm hex key so long as the BB stays in the frame (which it will)

Lock and Co for spenny. M&S for cheaps. If you want a 'classic' panama.

Stems with a single bolt on the steerer clamp - good idea? If so how come they dont all have 1?

Good idea =/= best idea.

It's just going to put pressure on a focused point. Two or more will spread the clamping load and be more secure. Sure @mdcc_tester can give you a more scientific answer.
Probably be fine though

Stems with a single bolt on the steerer clamp - good idea?

A tolerable idea, but in all ways inferior to two bolts, which is why the vast majority of steerer clamps have two bolts.

We don't really need science, we just need a broom handle. Hold one out in front of yourself with one hand and ask a friend to try to tilt it. Now grab it with your second hand at some reasonable distance from your first hand and make his job ten times harder :)

Yeah, but a broomhandle is long, a stem clamping bit isn't, so the difference isn't all that.

I therefore move that if a stem is a bit hip hop but only has 1 bolt it's ok to use, because hip hop defeats science erytym.

Vittoria voyager hyper, especially if planet X are selling them off cheap.

if a stem only has 1 bolt it's ok to use

It's worked for me for the past 6 or 7 years with my 1-bolt Ventus :)

My shop lifting habit has got truly out of hand and I now have a Liberty dressing gown with a magnetic tag on it - how do I remove this tag without having to take my dressing gown back to Liberty?

Magnets

It's stopped from turning due to the headset at either end of the headtube if it's preloaded though no?

Edit: tilting not turning

Magnets

How many magnets? How should they be applied?

You'd need to know how they work.

Magnets if it's got ink in, otherwise just smash it to fuck. Park snips and a screwdriver did for the last thing I stole.

Mitcham unperfumed rollon fits a) and c) but I've found it can leave white residues.

You'll usually find it with the women's antiperspirants

Why are Dura Ace 1/8" 15t cogs so hard to find? Velosolo claim to have a single 3/32" one in stock for £20 and there are some listed on Amazon for over £50!

That strikes me as inelegant, I've ordered a massively powerful magnet from Amazon.

Could you not send your manservant?
