IronDeer Gravel Frameset, Size S

This is the frameset behind our IronDeer Gravel rental bikes. We ride it every week on the Silver Coast: sandy coastal tracks, vineyard farm roads, limestone climbs above Nazaré and the tarmac in between.

It is built to race. The frame and fork are UCI approved, so the bike is eligible for UCI-sanctioned events, and the carbon layup, T47 bottom bracket and integrated cockpit keep it stiff and light. Rack and fender mounts mean the same frame can also carry you through the rest of the week.

You get the frame and fork with a UDH hanger and fully internal routing, plus an integrated carbon cockpit and a carbon seatpost. You choose the groupset, wheels, tyres and saddle, and we build it for free in our Nazaré workshop.

Who it is for

• Gravel racers who need a UCI-approved frame on tyres up to 50 mm.

• Riders training fast and riding long days on mixed surfaces.

• Riders who want one frame for race day and, with a rack and fenders fitted, for bikepacking or the daily ride.

• Riders who already own parts they want to move to a carbon frame, and want it serviced in Portugal.

Who it is not for

• Riders looking for a complete bike off the shelf: rent one or ask us about a full build instead.

• Riders who need tyres wider than 50 mm for rough, MTB-style terrain.

• Riders outside roughly 163 to 175 cm: other sizes have their own pages in our shop.

This size is built around a 380 mm reach and a 532 mm stack, with a 70° head angle, 425 mm chainstays and a 1016 mm wheelbase. Lower the stem for a race position or run it higher with the spacers for long days; the uncut steerer leaves both options open.

Each size has its own page in our shop, with its own geometry. Not sure which one fits? Rent the complete IronDeer Gravel in Nazaré and ride it before you order.

Free build in Nazaré

Buy the frameset and our workshop builds it for free. We cut the steerer to your stack, route the cables, set up the cockpit to your fit and torque everything to spec. The build takes 3 to 4 hours, so you ride away the same day.

Bring your own parts or choose them with us. To keep it a same-day build, all parts need to be in the workshop on the build day, new or in good working order, and compatible with the frame. If something is missing or needs replacing, we will quote it before we start.

Two starting points:

• Everyday gravel: Shimano GRX 1x, the setup on our rental fleet. Parts quoted to your choice.

• Race build: SRAM AXS with IRONDEER G50 SL wheels. Price on request.

Choosing wheels: read our Elitewheels G42 vs G50 CS real-world comparison.
