One would be sufficient but you might not find one going down as low as 5nm - I have one that goes
from 10-70nm. I wouldn't worry too much about going down to 5.

Doesn't matter, depends what sockets you've got already perhaps, you can always get adapters to
convert between them.

I got mine from Brick Lane (don't laugh!) It's actually a reasonably good tool!

Wheres a good place to buy the socet adapters that convert from sockets to say an 8mm (or 4,5,6mm)
allen key?

There's no need of any special adapter, an ordinary socket of the right size will do - 8mm I
think(?) for the standard allen key bits that fit electric screwdrivers.

The standard 1/4" (6 sided) bits work best in a socket with a little springy bit to hold them - if
you use a plain socket they fall out in an annoying fashion.

I found the standard halfords 1/4" socket set very useful for all sorts of small things (ok, mostly
on cars, and I actually mostly use the draper professional one I got, but the wife's halfords one
was pretty much as good and easier to find), and it should have one of these sockets. I then got a
rack of allen key bits from a decent hardware shop (mackays in cambridge) -
1.5 to 6mm. 8mm was harder - I got an individual 1/2" socket for that one. (I've got a 1/2" torque
wrench for car stuff. Much too big for almost anything on the bike).

Doesn't help attach to a torque wrench though! you would need adapters of various sorts.

I might. Things like stems are in the 6-10 range. My stem (ITM millenium) says 6-8nm.

If you have a superlight Mag stem + carbon bars then you'll need the lower numbers or you can easily
crush things.

Personally, I just go with "that feels about right" and no carbon bars 🙂

Aldi and/or Lidl had one recently; it's still at home, so I'll check the range this evening ...

I hate to be pedantic, but aren't there some commas missing (or a separator of your choice should
you be of a different nationality) from those large numbers?

There is not really much point going for a cheap torque wrench - unless it is accurately calibrated
(to BS2689/94 - I think +/- 4% of adjusted torque) it will not give you accurately tightened fixings
thus rather defeating the object.

If you find a wrench within your price range check that it meets this standard as well as having a
test certificate.

I very much doubt if you'd get one wrench to cover both ranges eg Britool do a 5-33Nm and a 12-68Nm
(have a look at radio spares site rswww.com - perhaps not the cheapest to buy). There may be some
merit for doing up bearings to the right torque - though I've always just used feel, but something
like a gear-clamp just wants doing up tight (ish). Not sure if your bottom bracket job is
pre-loading a bearing, or just screwing it together. Come to think of it, for doing up bearings,
mostly you couldn't use a torque wrench anyway as you have to use thin cone spanners or pin
spanners. Unless new bikes are different.

If you still really want one, you could get a decent 3/8" drive Britool on ebay for £30-40 or new
for £70+VAT. The £5 bendy bar type wouldn't be much use for the low torques you are talking about,
if indeed it's of much use at all. 1/2" drive ones are usually higher torque figures.

Usual warning that although I've mended my bike (and car) I'm no expert and don't know if modern
bikes are different.

PS - I have a 3/4 drive high quality ex-MOD wrench which goes up to 600lbf if anyone's interested.
It's a bit big though - I bought it by mistake on ebay.

It'll be good enough to get things to far far better than more or less right.

I only bought one for doing a head gaskett, and as long as all the bolts are similarly wrong
you're OK!

Answer to question: First one from "Auchan" (ie french supermarket) [stolen] Second one from
somewhere like Argos.

I just meant that in the "inexpensive" category you'd be unlikely to find a wrench that covered 5 -
70Nm. If a wrench starts at 10Nm you can get a feel for what 10Nm of tightness feels like, which is
bugger all, and if you need 5Nm just do it up to half of bugger all ;-)

Same here - also used it on gearboxes and such. I still have it, but never use it on the bikes; I
prefer to use a spanner the right length for the bolt size and feel the threads go up tight.

Ditto, but I had a TR7 for 18 months, so its a bit worn out now.

Do it up till the bolt shears then back it off a quarter turn.

I use one for doing up the cassette lockring because the serrations make it impossible (for me) to
tell whether it is tight or still needs a bit more.

It's also an easy fastening to do with a torque wrench.

This is one I find very easy. The correct torque is achieved with a 12" adjustable and a good hard
shove or two 🙂
