Ok I still have my three 26 vintage MTBs and I am building a 4th one. During two trail rides, my 26 MTBs allowed me better acceleration and better handling than those who were riding 27 and 29.I also have 3 pairs of mavic XM819 rims in spare in case of, that I bought back then.

You can find mavic 217 orX517 sup ceramic rim brakes on the bay and have them assembled by your bike shop.Bike 24 is one of the best places where you can buy 26' tires.
