ENVE SILCA Valve Extenders 34MM
The ENVE SILCA Valve Extenders 34MM valve stem extenders for tubular tires and tubes with removable valve core. The 34MM set is optimized for the ENVE SES 3.4 and SES 3.4 Disc or any ENVE tubular or non-tubeless clincher wheelset. If you have the SES 7.8 or SES 7.8 Disc you will need the 75mm set. ENVE recommends that the length of your tire/tube valve and the length of your extender exceeds the depth of the rim by at least 10mm.
