Novatec Jetfly hubs

[Cyclenon]

Hi,

I'm interested in buying the Novatec Jetfly wheelset (http://novatecusa.net/project/jetfly/) but I was wondering if anyone is able to recognise the XA561SB/XA562SB hubs?

I'm wondering if these are in fact A291SB/F482SB, as they are not sealed well enough for the British weather and a number of wheelbuilders avoid them (http://thecycleclinic.co.uk/product...20h-24h-slotted-drilling-10-11-speed-290g-red)

"If you use them for winter training rides when the road are always wet it may take there toll on the bearings. The Cycle Clinic stocks other hubs for this kind of abuse. If you use them on dryish road and they will be fine, but all light weight hubs are like this."

Is anyone able to recognise them from the photos?

And here are the A291SB / F482SB:

Whatever they are they will be fine. The bearings are sealed anyway - and even if they do need to be replaced, it is a simple process.

Thanks for that.
Do I need a bearing press as shown here or can it be done without one?
