...finally the shimano compatible 5's on Bike-Discount are listed as LG and HG - any idea what the HG stands for?
It's a gearing description, stands for "Hyperglide", used extensively to describe the compatibility between Shimano's chains and cassettes. I think the other standard ought to be "IG" (for Interglide), and from memory it is to do with different chain widths for the same number of gears (fractions of a mm on 8 speed). You can use IG chains with HG casettes/chainrings, but not t'other way around, or that may be 'vice versa', I can't remember. It's a long time since I saw anything other than HG, at least when talking about MTB components.Pot, a freehub is (generally) servicable, maybe have a look at stripping/cleaning/regreasing your current rear wheel regardless of what you decide as that way you'll end up with a winter set.
The are plenty of online and YouTube tutorials to get you started.

Thanks for the info YellowJack & others.
The LG & HG codes were applied to a specific wheel on the Bike-Discount website - not different variants of the same wheel.
http://www.bike-discount.de/en/buy/fulcrum-racing-...
The LG in this case is because the latest version is a 'large' - larger rim width than the previous model.
It was the HG which I was unsure of.
Took the noisy CXP22 out again for 30 miles today and it was actually a lot quieter. I'd only ridden approx 500yds to test it the other morning after new bearings and it was really noisy - only thing changed was i'd had the QR open so might not have tightened it as much as before (I tend towards quite firm closure).
Having been paying more attention to the wheel I did a comparison spinning the front and rear wheels by hand with about the same force. I was getting about 50 revolutions of the front wheel to about 10/11 of the rear. It also felt a little more hard work riding today (ignoring the wind) particularly noticable uphill where I was having to work hard to keep pace with my riding buddy wheras i'm normally breezing ahead (or maybe he was up for it today and I had lead legs on). I get that the rear has a freewheel which is loaded up by the chain but would you expect it to spin up that much less than the front ? Would over tightening the cone bearings add this type of resistance ?
Whilst i'm making an industry of tapping the PH collective knowledge ........ the Fulcrum suggest weight limits for the Racing 5's in the user manual:
- If you weigh over 109 kg/240 lbs we advise you not to use this product. Non compliance with this warning can damage the product irreversibly.
- If you weigh 82 kg/180 lbs or more, you must be especially vigilant and have your bicycle inspected more frequently (than someone weighing less than 82 kg/180 lbs). Check with your mechanic to discuss whether the wheels you selected are suitable for your use, and to determine the frequency of inspections
I'm pretty much bang on the 82kg having shed 9.5kg since Jan but accept i'm most likely to creep up rather than down (whilst there's an incentive to keep the belly at bay anything less than 12.5 st on me at 6ft leaves me with twiglets for arms and legs !). Have people in the 82 to 109kg range got along fine with the 5's or is this a fly in the ointment. Moving to a 20 spoke wheel just makes you think.
Price match has been agreed with Wiggle but if anyone has spotted 5's for under £144.36 (£148.80 - 3% Quidco) then please do shout out.
Thanks again.

Not sure why but I was under the impression that this is a pretty meaningless test due to other forces resisting your progress (wind resistance / tyre rolling resistance etc.) being far greater. Happy to be corrected though.I'm 80kg, and I ride cyclocross on my Fulcrum 5s, other than a dropped chain breaking two spokes I haven't even trued them up. I also ride some of the local MTB Challenge rides on my 'cross bike, the wheels are well up to a bit of abuse, so for road riding I can't see them being a problem.

Are they just the standard 5's or are they the CX versions ?One careful owner...
Update on the Fulcrum Racing 5's having just got in from my first trip out on them - short 16 mile ride as i'm off for a quick 9 holes now.
- much smoother - i could see the old cxp22's vibrating away like mad over rougher surfaces - I therefore felt much more confident on some of the downhill sections.
- Felt like I was getting more power down on the climbs - just felt stiffer
. I normally climb in the saddle (just doesn't feel right out). Had a little stint out of the saddle on a climb today and it actually felt ok.
- Nice freewheel noise
- Red nipples !
