When you proposed putting Big Apples onto your Nova, I was concerned that the stock rims might not be wide enough to handle BA's 2 inch width, even though they are also the 406 size. Make sense?
Hi Joseph
So got the Schwalbe Marathon 20 x 1.75 Kevlar Belted today from
biketrailershop.com for $29 each. I was afraid that lower bottom bracket would not fit the Big Apples whic are 2.0 so went with the 1.75 Marathons. I installed both in 30 minutes, the rim is not a problem, a real breeze. Filled em up with 70psi and they feel great riding. These fit well but I doubt the big Apples will fit on the rear (you could easily put a Big Apple on front though). Here are a few pics to show the clearance.
I will update more later on, the M wave rack works great but getting more normal panniers which will prevent any and all heel strike as well as likely fitting this out with a Brooks Saddle and some Planet Wave fenders. I am also planning on putting on the front derrailur and picking up a Shimano 600 crank. I found the SIS shifter set for $15 online and will put that on and have an extra shifter since it comes with both. I am guessing I won't need more chain but if I will let me know. DVC45 has a Shimano 600.
I don't know why I can't post pics. Click
