I have 3 sets of ENVE 29 XC, so in my opinion, no.
1 set of 28 hole tubular on Tune hubs for the road bike.
1 set of 32 hole clincher on Tune rear and SON dynamo front for the winter bike.
1 set of 32 hole clincher on Chris King R45s for the cross bike.
They aren’t particularly interchangeable since one set is tubular, 1 set has a dynamo front and the other set is standard. 1 set has 25mm road tubulars, 1 set has 30mm road clinchers and 1 has 34mm cyclocross clinchers.
I am just building up a single speed 29er, and have thought about another set, but in the end went for Stan’s Crests instead.
Life is short. Buy what you want and enjoy!
Plenty of good deals about on 26″ right now. The Fulcrums are particularly good value.
