Rear Dura Ace Hub on Hed Belgium + rim (nice and wide for a road rim). Built with Sapim superlight but strong spokes.
11 speed hub. A lifetime of riding remaining (it was onbuilt for the IndyFab which is now retired as I have a disc bike) and built to be superlight.
Just the hub was about £130 on offer. So £100 seems a fair price for a quick sale. Second rim also available if someone wishes to build a matching wheelset.
Postage at cost (probably about £10)
NB add £20 if you want the tubeless valve, fresh sealant and gp5000 700 x 28 (or is it 700 x 25) installed.
