For everyone still sitting on the wheel size fence it looks like Cove may have just the frame for you. For 2014 the iconic Hummer frame will swing either way; 27.5 or 29, thanks to it’s sliding 142 x 12mm dropouts
The Ti framed Hummer (manufactured in the US by Lynskey) is designed to give a 67.5º head angle running a 140mm fork, and with it’s 44mm head tube the possibility to slacken that off further is there.
ISCG05 mounts, asymmetric stays and a PF30 BB complete the frame details and all add up to what should be a pretty capable hardcore hardtail.
The Hummer frame is £1595.00 and available from Silverfish.
