Titanium, or Chromoly rails?
Chromoly rails are often used in most saddles. Chromoly (Chrome Molybdenum) is a strong, durable and resist bending, and is not as expensive as Titanium rails. If you’re looking to save a little more weight on your saddle use Titanium rails. Titanium rails often require special workmanship, so these saddles tend to be more expensive than their chromoly-railed counterparts.
