I got a super good deal from a friend of mine that got me an extra unbranded carbon rear disc.
It’s 700C clincher rear disc that can change the hub for a speed hub.
If someone is interested I can sent it over (post paid by the buyer), I am based in the Czech Rep. and I usually only go to Helsinki in the summer… if it’s not sold by then I can bring it with me.
It was used only 3 times in the velodrome. Askign price 330 EUR ONO
