I've been offered a stupidly good deal on a new Sanderson Soloist
(£240 incl headset) but need some questions answered.

I currently have a singlespeed Inbred (horizontal drop-out) and the plan is just to swap everything over. I also have a Sanderson Life so know all about the build quality etc.

Can I use a QR rear wheel on the Soloist? Anything else I should think about –

Cheers!

It's an EBB so QR should be fine Shirley?

Al has it.

It is a standard QR dropout. Ritchey to be specific.

normal qr is just fine on mine. And yes £240 incl headset is a well good deal. Only issue I had with my parts swapover (18" frame fwiw) was the floodgate adjuster on my fork catching the downtube: (there had been loads of room on the old frame with same headset so I had never thought about it until it was built up) -I had to get a slightly 'stackier' headset was all.
