Can I run 29" wheels on my 1x1, Troll, Big Dummy, Pugsley, 26" wheel LHT?
Yes, they'll fit but remember that you won't be able to use rim brakes. Keep in mind using taller wheels raises your bottom bracket height, decreases stability, and adds greater potential for toe overlap. In short, it will change the ride characteristics of your frame. But we ain't your moms and we sure ain't gonna tell you not to do it. We encourage experimentation of all kinds, but do not specifically recommend this sort of behavior. Get it?
1x1 - sure, but clearance will be tight in the frame and older (80mm) forks
Troll - yeah sure
Big Dummy - only skinnies (700 x 25max)
26"LHT- you got no brakes!
