I've got a disc brake wheel on my 612 bullet. The wheel was a tidy second hand one off ebay.
I was looking closely at it today and something looks horribly wrong with the spoking on it.
From a distance it seems ok.
Look closer and there are multiple spokes that seem to be entering the nipple/rim at the wrong angle and landing up the wrong length. Seems like a dangerous amount of thread not engaged in the nipple on a few of them.
I've had a really good look (I've built quite a number of bicycle wheels, only a couple of motorbike ones) and it looks like a totally vanilla cross pattern with all the spokes routed to the correct holes and with the correct overlaps. The spokes are all well seated in the hub.
The spokes are stainless which suggests export model manufacture or home built? It's a 19" chromed steel rim. The hub is grey powdercoated.
I'm now wondering if this is the correct rim? Maybe a dum brake rim built onto a disc brake hub? It seems that the only "wrong" thing is the angle the nipples protrude from the rim at. Also, did the disc brake models even have chromed rims?
There is a part number on the rim itself:
Pretty sure it reads 9W M2/1.85X19 ADEFP 07-2004.
Now if that's an enfield rim and the last bit is a date code for July 2004, that would pre-date the use of disc brakes yeah?
Ok, another thing confusing me. Because in our hosts wheel rim section, it's expressed in bold, capital letters that drum and disc rims are not interchangeable. Yet they sell a disc brake conversion kit that has a hub and spokes to build onto your existing rim... I'm wondering if this is the result of one of those?
