Limited Warranty

SILCA LIMITED WARRANTY 

Parts covered by SILCA Limited Warranty are considered to be subject to wear through normal use or are consumable subject to degradation through the course of their daily use.  SILCA guarantees the life of these items to be at least 2 years from the date of original purchase.

    So we've always noticed how really expensive tubulars had such nice valve cores with smooth edges and high quality seals that resisted sticking.  When we started developing SILCA Tubeless valve stems, we set out to find the best cores, and realized that only a handful of companies make them globally.  After a lot of phone calls, emails and discussions, we knew instantly when we had found the ones we were after.  Fully CNC machined with roll-formed threads these cores give themselves away with their spun-formed tops that keep the valve nut from unthreading too far.  Most companies crimp the threads here which damages them such that the nut cannot thread over..we find the extra effort to spin form a perfect little mushroom head on the top of the valve to really say it all: these are carefully made.  Icing on the cake is the use of fully synthetic seals for both the stem seal and the core seal, this means that the core will resist aging and cracking for far longer while being significantly more resistant to both synthetic and natural based sealants if you are using tubeless.  Best of all, this additional thought, care and attention to detail costs almost nothing over lesser cores while saving you pain and suffering over the coming years.

    Presta Valve Core

    With tubeless tires using sealer that clogs the valves it becomes paramount to have better valve cores so they remain open and filling up air remains possible.

    Keeping the air in despite sealer contaminated is essential too.

    Best Quality and Handy

    Very handy to have spares for when you mistakenly bend the top of the valve. I carry one with me just in case I screw up inflating a tire.

    Quality replacement

    OEM stem valves don’t last forever in a tubeless sealant setup and an inventory of these quality replacements are a must have in my tool chest at home.
