Rear wheel parts & spokes for 2011 Ossa TR280i

[Stout]

Hi all,

While out free riding in the scrub this morning, a stick has flicked into my rear spokes, bent a couple of them and in one case, snapped the threaded boss that holds the nipple to the rim. The real problem is that this lets the air out of the rear wheel.

So I'm after any leads on a supplier for Ossa bits now, or just a lead on these wheel parts if they are common to other makes (I think I've seen them on other bikes, just can't recall which ones) or in fact any help at all if someone happens to have some in their parts bin.

I need to get the bike fixed for an event next weekend, so any help appreciated.

Nathan
