Any question answered...

Braze on in the way.

Duh, Gotcha

But spendy

Singlespeed but not NW. Rear mech is an XTR 10s mid-cage but not clutch, because eBay.

I like the idea of the DM-type guides because it's one degree of freedom for it to be wonky, whereas ones with a simple bolt and cylindrical spacer will inevitably spin unless you tighten it to the point of crushing the plastic.

Is there any negatives to riding a positive degree stem, other than it looking terrible?

The viewing angle is a bit off if you mount your computer to the top of the stem. Apart from that, it's fine.

recommendations for a narrowide chainring for a 4 arm campag chainset?

Sorry for the repost:

Anyone has / ever used one of these?

I've bought one second hand off ebay. without having an immediate opportunity to try it out Im a bit dubious that some damaged threads (at the base, near the handle) will stop it from working correctly, as one half can't fully screw in to the other...

Hope that my ramblings make sense, should I be concerned?

Are Lumie Bodyclock alarm clocks (or other brand light-up alarm clocks) any good? Does anyone have any experience using one?

Girlfriend had one for a year or so.
Can't say I noticed much of a difference getting up but then that could have been that she continued to set the thing 30mins before she wanted to get up and then kept hitting snooze.
But it does wake you up, and it's not jarring.

So it's alright. Did the job, but not a revelation.

Cool, thanks for the reply.

We have one, light starts to build/increase to whatever level you set it to the night before from 30 min before whatever alarm you set. I mostly find it handy to not have to fumble about to turn on a light when the alarm goes off. Other than that I don't know if it has any other kind of effect.

Also handy if either of us have a very early start and don't want to annoy the other too much. Just set a lower brightness.

Being able to snooze it by giving it a whack is also satisfying.

This great tool has worked out that i can have the same reach with only a 23mm (-6 stem) or a 27mm (-8 stem) drop on the front end compared to my position on the tarmac. In terms of bike fit. Is 23-27mm drop substantial?

If you have it in hand with your physiology, it's nothing. If you don't, it's everything.

What's the suggested torque for an integrated seatpost clamp (is that the right word for it?) on a Bob Jackson frame, clamping a Chinese carbon seatpost with a coke can shim?

PS - I'll let you know if it stabs me in the arse.

Edit: I'm not sure that is the word for it. The clamp is part of the frame, the seatpost is just a standard one. Not a stupid topper thing.

What is it?

I’d guess 5-7 Nm

But you’d need to check manufacturers specs

If you hold a wheel with your hands on the axle and spin it then let go with one hand, the wheel stays upright but also turns the away from the one side holding it.
Therefore, do lefty forks pull slightly to the right? And if not, why?

Because the wheel is rolling along the floor?

Also, presumably the axle-Lefty interface is stiffer than that between your hand and the wheel?

I have a PDF with a selection of music tracks embedded in them. Is there a way to export the embedded file? I'm not sure I want to try recording it playing. Seems a bit messy.

if not, why?

What you're seeing is precession, and the turning moment is driven by a torque trying to tilt the wheel, in the case of holding it in one hand driven by gravity.

When you hold one end of the axle, your grip is effectively a free pivot, so it doesn't react the torque generated by the mass being displaced from the fulcrum, so precession takes up the slack. On a Lefty, the joint between the axle and the leg is rigid, so it reacts the gravity driven torque and precession doesn't happen.

Is there a way to export the embedded file?

Yes. I can't remember how just now, but I know I've done it before, it involved a command line tool for tearing pdfs apart into their constituent files

Ugh. Ok, I'll use a different track for now. Can't be dealing with that at 10 o clock ahead of a 4am start.

Obviously, because nobody can use the command line any more, there are online tools to do the job for you, but I haven't tried any of them to see which ones actually work. Try some of the results from https://www.google.co.uk/search?q=extract+audio+from+pdf

That was nearly full-LMGTFY which I entirely deserved. S'ok, client didn't send me the correct track in the first place so I already went to too much effort seeing if there was a solution. I'll let them send it in the morning and they'll just have to wait until I'm back to amend it.
