Needs a 180 rotor (backing up the +20mm thing 8) ).. keeping my peepers fixed on ebay for something that ends with just my bid :lol:



+10 mm as it is difference in radius.

... and as ^^^^^ say, looks correct to me too.

The rotor I have is 160mm... the one I need is 180mm... now, I'm new to this rotor malarkey so how you get 10mm from that may require a little explaining

I dont know how they quote / spec these '+' sizes but to answear your question - a 10mm increase in radius will give you a 20mm increase in diameter :D

Radius = from center to edge.
Diameter = from edge to edge across the widest part.

02gf74 is suggesting that they spec the bracket size on the change in radius.

WD :D

If only.. .. would've done the tinnitus so much good :lol:

No.. I didn't realise a 6" bit of tube was stuck between rim and tyre and the floor pump took care of the rest :lol:

Also managed to snap a tyre lever..

Learn a little about axles..

Fit a headset and have a bit left over (not even going there!! :lol: )

Can't wait for tomorrow Image

It's the law for there to be bits left over when working on cars..

Worse when you've been doing brakes :shock: :lol:
