Trek EX 650b Front
Recently here at Sixfifty we decided to do a bit of experimenting. The result was this, an EX with a 650b up front and a 26″ in the rear.
The modified EX is running a 2011 Fox Talas 120-150mm QR 15mm fork. The American Classics 650 BXC wheel mounted with a WTB Wolverine 2.2 clears just fine.
We fully deflated the fork and checked the tire clearance to make sure no contact with the frame would happen. Overall the bike felt just as nimble, but with a bit more stability in the rougher sections.
