Any question answered...

If I wanted to make this, where would I get the small expansion spring and grub screw clamp thingy? Or can someone please tell me what phrase they're called so I can search properly please?

The grub screw clamp thing looks like the brass innards of a connection block/strip chopped in half. If you take one apart there are brass tubes with two grub screws.

Not sure about the spring but there's bound to be a few options on ebay

Mine seems fine. The Enve forks is stupid stiff in comparison, but that's not always a good thing.

Lock-out sucks. Don't bother.

Which bottom bracket is the Un55 of octalink spline style that fits FC 7703 cranks?

I dont understand. tmk un55 are square taper.
octalink tapers changed, you need v1. there are plenty of 105 5500 bbs new for cheapz. for real butter bb 7700/10 bbs are also still produced for the track cranks and to be had new.
7703 is triple though right? then you need a 118mm one instead of the standard 109 for track and road

5500, V1, 118mm
e.g. http://www.highonbikes.com/drivetrain/bottom-brackets-road/shimano-bb-5500-105-octalink-mtb-road-bike-bottom-bracket-68-118mm.html
Double check that they are sending the V1, that's what their ebay listing says but it doesn't appear on the web site.

ahh now I understand; cheap ans cheerful bb. get bb-5500 in v1/115.5mm flavour if triple

7703 is triple though right? then you need a 115/115.5mm

118/118.5 for road triple Octalink

shit; quoted for posterity so too late for ninja edit..;)

Thank you @mdcc_tester and @Rodolfo

Edit: I might actually end up putting these on a track bike, then I look for a 109mm spindle, yes?

Ah perfect thanks!

@Howard I'm well aware, mine is shit, I'm doing it to get it semi functional as it won't stay open.

Which damper is it? Motion Control? They are pretty easy to fix / replace.

I need a wide (about 3 inches) but small radius elastic band .. where can I buy one?

Chop an inner tube?

genius, thanks! A more cloth-y texture would be better .. but fall back on tube isnt a bad idea.

Can I use some kind of thread lock on my stem bolts? They're torqued correctly but seem to loosen off over time (or someone in the work carpark is trying to tell me something).

The forks are RockShox Recon Gold RL. I saw some details on how to unlink the internal dampening spring and pop the motion control cap on, but that was a different style cap (the same as the one in the video with the circlip mine has an Allen key, so I don't know if it'll work.

Don't think these are motion control.

I use Loctite 222.

The finger of some workman's gloves?

If you go skip-diving, you'll soon bag a pair.

Its basically to wrap around my wind jacket so it packs more compact (and stays that way) in jersey pocket.

Sweatband or football captain's armband?

Tubigrip... (or a crusty gym sock)
