Now what I am after is, I wish to put some mag wheels on my fixie, there are some great one on eBay for around £160 a pair. They are flip flop fixed and freewheel, BUT the sad fact is their 26".
I have used these mags (composite) before on a mountain bike, but wish to purchase the fixed gear version. The axle on the rear is 120mm wide which is perfect for single speed bikes, but the wheels are 26" which is fine if you don't want to have brakes, but if you are going to use the bike in freewheel mode than you must put brakes on them.
Without changing the forks (also the front wheel is not disc compatible) can I buy a extra long reach caliper that would drop low enough to catch the rim of a 26" wheel?
