EnduranceChip is the best option for ultra-endurance events or training chains to get the most longevity out of your components. EnduranceChip is a semi-synthetic wax blend boasting some of the longest molecular chain lengths possible in a wax for ultimate durability. Adding EnduranceChip to SecretBlend can permanent increase the distance between re-waxing by as much as 2.5X (up to 750km) while still being as fast as the top wet lubricants and significantly faster than any dry lubricant. Add a second chip for even further single application longevity.

Shipping for some reason took weeks to arrive. Item arrived after I needed it so it was no use to me.
Great unit, works as expected. Sierra was quick to deliver and easy to work with. Thanks!
Excellent helmet, nice colour and great performance. It is very fit ti the head.
Thank you !!!
Great softer materials but not the same support as the previous season. Pockets are large enough to fit stuff but the straps don’t support well. No chance you’re getting a water bottle in there. Also the bin straps position themselves right on top of your nipples. You’re going to notice that after an hour of pedaling and sweating.
I really liked the previous version so
Much that I wore 2 pairs out with 6000 miles. These new ones will be lucky to make it into rotation.
