Replace the rail, not the saddle.

The Monarch Saddle was designed around a removable rail system, so a damaged or bent rail doesn't mean replacing the complete saddle. Choose 4130 CrMo for the standard matte-black chromoly setup, or Ti-MX for a raw-silver titanium-alloy option that creates a complete Monarch Saddle setup 22g lighter than the CrMo configuration.

  • 4130 CrMo: 4130 chromoly steel / matte black
  • Ti-MX: titanium alloy / raw silver
  • Rail profile: standard 7mm round
  • In the pack: 1x replacement rail + 1x instruction sheet
  • Fitting: reuses the existing Monarch nose cap, cap screw, rail bolt and washer

Designed for the Peaty's Monarch Saddle. Use the existing Monarch servicing guide for the full fitting procedure.


01 / Replacement rails

Replace the rails. Keep the saddle.

Bent or damaged a rail? The Monarch was designed so that does not have to mean replacing the whole saddle.

Its removable rail system lets you replace the rail you need and keep the Monarch Saddle you already know. Choose 4130 CrMo for a straightforward replacement, or Ti-MX for the lower-weight raw-silver option.

Serviceable by design

Service it, don't bin it.

The removable rail system is there for exactly this reason. Replace the part that needs attention, rebuild the saddle using the Monarch service process, then get back on the bike without throwing away a saddle that still has plenty of riding left in it.

02 / Choose your rail

4130 CrMo or Ti-MX?

Same Monarch Saddle. Two rail options.

Choose matte-black 4130 CrMo for the straightforward replacement most riders need, or raw-silver Ti-MX for the lower-weight option and a different finish.

03 / Replace. Service. Ride.

Built to come apart. Built to go back together.

Replacement rails use the same removable system designed into the Monarch Saddle from day one.

Reuse the existing Monarch fastening hardware, fit the replacement rail using the full servicing procedure and check everything is correctly seated and secure before riding.
