Running any components that are not originally intended for use on the bike will void your warranty. This includes a shock with a longer than stock stroke (stock stroke = 50mm). A longer stroke shock will result in insufficient clearance between the seat-stay bridge and seat tube during bottom-out condition, failing to meet our minimum clearance requirement. Cycling the suspension through its travel might make it appear that there is sufficient clearance, however, this does not account for the compression of the internal bottom-out bumper.
