not sure, but i do know that a tallboy isn't a pivot, and the best thing about santa cruz is they have a great warranty program, which you may need to use. go with the pivot.

you are asking about a pivot, but if you want a 29er and are open to suggestions, i would recommend a turner sultan, but that is only because i really really really really love my turner 5spot and i really like turner as a company.

again...if you want a pivot 429, get it, it's a great bike.
