Which workstand?

Actually, another factor against the last three is the QR holder for front forks.

I have a 29er with Fox sus forks on the front, and they use the 15QR axle:

Not convinced the flat stands with road QR would work here at all.

If you've only got a small amount of space, how about mounting this to a secure bracket on a wall, then folding it away when not in use?

Two reasons:
1) I can't drill into my walls (stone, reinforced concrete + steel in every wall).
2) None of my rooms have space, I'm basically going to set up in the communal hallway

So it does need to be a foldaway stand, but one that can take a heavy bike whilst being very stable.

borrow mine, see how you get on with it...

I can cure 1), but not 2)

VB which of your bikes is "heavy" by normal peoples standards?

The Robin Mather with Schmidt dynohub, Rohloff hub and racks.

The issue being, take off the front wheel and the bike is now very heavily balanced to the rear. By an extra 1.5KG. And because this weight is all out at the rear axle, it acts like a lever.

Whatever stand I choose has to be fine with a very unbalanced distribution of weight, and still be stable.

This is basically why I'm looking at more expensive three legged stands.

ribble have some on offer for £50.
i prefer the ones that clamp the seat post and find them more sturdy than the BB supporting ones.

I bought this one a few years ago, thinking it would just about do the job, but have been very pleased with it. I actually wouldn't want to exchange it with a more expensive one if someone offered it to me, very good value, very sturdy

BikeTool Aluminium Workstand

That's a great price

Yup, but I'm still going for a 3-legged one.

VB I've got one very similar to this:

It rocks as it doesn't rock.
I also use one of the same design at work which is all good holding a fuck heavy Batavus with dyno front hub, alfine rear hub and all manner of other heavy bits.

Fabulous, that's basically what I wanted to hear, that someone with experience can recommend one.

I'm probably leaning towards that (or a cheaper variant almost like that) as it appears to be the most compact when folded too. Just didn't know how stable it might be.

The one downside to it is due to the way in which the clamp closes you can't work on bikes with aero seat tube.

Ah, that's one thing none of my bikes have. Should be good for me then.

just clamp a fake cctv cam into it when not using? I'm sure you could fool people...

Just seen that www.probikekit.com are doing a 10% off thing too: EXTRA10

Expires out on Tuesday.

So may well make me buy it before then.

Scratch that... 20% off using LONDON20, expires midnight tomorrow.

Opted for this one: http://www.probikekit.com/uk/tools-maintenance/bike-storage-workstands/bike-workstands/feedback-sports-sport-mechanic-workstand.html

Good price (especially with 20% off), and a lot of stand for the money.

Too late to vote for the PCS 10?

I went for this one in the end:
http://www.probikekit.com/uk/tools-maintenance/bike-storage-workstands/bike-workstands/feedback-sports-pro-ultralight-workstand.html

It's currently 30% off, so it brings a good stand closer to the price of a cheap stand. Still more than the really cheap ones out there, but sturdy as hell.

Already set it up once, and held my heaviest bike really well. Virtually no wobble at all.

virtually?

Well I was curious as to whether it would hold 75KG of me at the same time by jumping in the air whilst pushing down the front bars.

I can't fault it for a little wobble under that scenario. It's only rated for 35KG. I can fault myself for stupidity, but hey.

After a fair bit of research I bought a Tacx T3075 Motion workstand - £89.95 at Ribble at time of writing. It's more of a work bench than a stand but I wanted one that the bike sat on rather than one which clamps the frame (carbon fibre frames innit).

The bike sits on the bottom bracket and it secured by the dropout (front or rear).

It folds fairly flat for storage and gives a rock solid work platform.

What if your bike has sensor magnets under the bb shell?

I saw that one but generally ruled out stands in which you must remove the front wheel.

Because: Track nuts, 15QR, security bolts, Schmidt dynohub (mucking around with connectors).

Basically, I have too many bikes in which dropping off a front wheel is a pain in the arse or I suspect the stand won't accommodate the forks (the MTB sus forks).

For road bikes though. I actually reckon that kind of stand will be much better to work on (you don't get a pole in the way on one side of the bike).
