Anyone have any experience of transporting a wheelset by plane?

Hello all!
I've been to several lbs this morning going to find a spare crown race for an FSA headset (I want to be able to swap forks without having to extract it everything) but no luck.
I'm not sure which one to buy online...
It is for this headset;
http://www.planetx.co.uk/i/q/HSFSOXCX/fsa-orbit--x-cx--headset
(Although I'm not sure my one said "orbit" when I got it)
As advised by Tom, I looked at the bearing writings, which says angle is 36°x36° (the full stuff says "TH industries 1-1/8" - ACB 36°x36° 872#)
However a mechanic told me this morning it was a 45° one (which is why I wrote this... But of course it could be wrong)
Any idea where I can find this?

Buy a complete headset without the cable hanger http://www.planetx.co.uk/i/q/HSFSOX/fsa-orbit-x-headset, then you'll have the crown race you want and the spare bearing cartridges you'll otherwise be asking us about in a few years time.

Buy another headset and just use/fit the lower half of it. The top half of it with the hanger and stuff won't be bothered by that.

@clockwise and @mdcc_tester , sounds like the right thing to do. Thanks, will proceed...

British Cycling Tech. Reg. 3.3 gearing for younger riders.

mespilus jr. spent this morning, his second, at the Hillingdon Track,
gaining his Bronze accreditation,
and being allowed into a 5 lap race with far more experienced
members of Hillingdon Slipstreamers.

As a 14 yo he is restricted to a gear of 6.93m,
meaning that the bottom five gears are currently locked off.
(His mother panicked and ran out and bought him a bike
off the peg with an 11-speed Dura Ace groupset).

His current smallest sprocket is 16-toothed.
Is it possible to mix'n'match some combination of CS5800 105 cassettes
to give him a 16-17-18-19-20-21-22-25-28-32-?

or is there a cheaper option based upon 10-speed cassettes and a spacer?

Riddle me this:

• PF30 BB shell
  
• Wheels MFG PF30 BB
  
• Installed a BB30 crankset
  
• Axle is too short (104mm) to be used in this application (I believe), which over-compressed the bearings - it certainly destroyed the bearing shields when tightened to spec, and the cranks would not rotate
  
• It worked perfectly without any bearing shields
  
• I got a slightly longer axle and thinner bearing shields, installed it all, fine
  
• But then the "crack/crack/crack" of doom started
  
• Pulled axle, bearings felt gritty when rotating the inner race
  
• Knocked out bearings with screwdriver and hammer
  
• Now they feel perfect- butter smooth. They're ceramic, also
  
  

Questions:

1. WTF?
   
2. Do I press these bearings back in, or are they FUBAR? (They feel fine).

If you have 11-speed shifters, you're stuck with 11-speed cassette spacing. Oddly, Shimano have abandoned junior gearing for 11-speed, they always used to make Ultegra cassettes with big sprockets at the top end.

16-17-18-19-20-21-22-25-28-32

I think that could be assembled from an 11-28 and an 11-32, you'd need a spacer between the lock ring and the 16T to take up the slack. With some frames, you may crash the chain into the seat stay by using such a large sprocket. It's probably easier just to leave things as they are.

The other option is a 1×11 set up - 36/11 gives a development of fractionally under 6.93m with 700×23C tyres.

Knocked out bearings with screwdriver and hammer. They're ceramic

With the available budget, I'd have bought steel bearings and the right tool :-)

I put the ceramics back in, they "went gritty" as soon as they were pressed into place.

Removed them, pressed in a brand new set of steel bearings, they now barely rotate.

Fuck.

Thank you for your prompt answer.
looking at the frame, a Cube Agree,
the chain stay looks as likely to be snagged as the seat stay.

I guess that Shimano don't offer a 36t chain ring as the inner of a double,
allowing the 50T outer to be locked off?

I thought 52/36 was all the go with the hipster-roadies these days. Which cranks do you have? Should be pretty easy to get a 36 for either 110mm 5-bolt or the new 6800/9000 pattern, Shimano do a 36T for 4-bolt 110mm and there are millions of possibilities in 5-bolt 110mm, since it actually is one of the few genuine standards in cycling gear.

Please pardon my error upthread,
the groupset is
Ultegra 11 speed, 50/34,
with as far as I can see just the four bolting points,
So,
http://www.rosebikes.co.uk/article/shimano-ultegra-fc-6800-chainring-713812/aid:713814

would do, (realise the posrage is almost as much as the chain ring,
just happened to have a tab open on the Rose bikes webpage)

Even with shipping from Germany, that's still cheaper than I can find it in the UK.

Ovalled BB shell?

mentioned on the train journey out to the midweek ride last week was a calendar-view link to see in one-click forum-related stuff happening,might anybody have this link within keyboard tapping range?

Will an Ultegra 6700 double 10sp front mech work in an 8 speed set up? Discovered the 9 speed Sora mech I've been using is bent and twisted!

Is there a sort of insert I can buy for my track pump? I have the SKS Aircompressor 12.0. It has a sort of L shaped ending and I would like a sort of extension to a straight one so I can use it on other vehicles. I can't use it on all of my mopeds or my car at the moment.

I would like an extension on the big one that goes from this:

To a straight one

Using a high pressure track pump on car tyres will take days, thanks to the small stroke volume. Much better to get something designed for the task.

Last night,
I thought, 'Why not ask Cube?'
they should know the physical distances involved between the axle and the seat/chain stays.

So a detailed email was sent, in hope, from their online 'Contact Us' page.

Just received an answer:
'I can recommend a Miche 11 speed 14-26 shimano cassette in combination with a 46T outer chainring (shimano makes a cyclocross specific ring for the new shimano 4arm cranks in a 46T).'

Not really. I've done it before in about 3 minutes.
