The Yoeleo Altera G21 DB Gravel Bike Frameset is Yoeleo’s adventure-focused gravel platform, designed to offer more storage, flexibility, comfort and control compared to the standard G21.

The package includes:

  • G21 frame
  • Fork
  • H21 carbon integrated handlebar
  • Seatpost

The frame is made from High Modulus Toray 800 carbon fiber in a standard Champagne finish, with custom painting available. It comes in sizes 45, 49, 52, 54, 56, 58, 60 cm, with a claimed weight of 1170 g (56 cm, Champagne) and 1150 g (56 cm, Raw).

The bottom bracket is a T47 inboard bearing shell (85.5 mm), compatible with:

  • Shimano GRX 24 mm spindle,
  • SRAM DUB / DUB Wide,
  • SRAM GXP.

The cockpit is built around the H21 carbon integrated handlebar with 15.2° flare, available in 400 / 420 / 440 mm widths and 80 / 90 / 100 / 110 mm stem lengths. Claimed weight is 360 g ±15 g (420×90).

The fork uses a 1 1/8" – 1 1/2" tapered steerer and 12×100 mm thru-axle, with a listed weight of 480 g (painted, 56 cm frame). Two fork styles are offered: with mounting holes or without, depending on your bikepacking needs.

The seatpost is now round 27.2 mm, weighing about 95.2 g (without clamp). This new Pro-Flex Seatpost is designed to absorb road buzz more effectively and allows easy use of third-party posts or even a dropper post.

Key compatibility points:

  • Rear dropout: 12×142 mm thru-axle.
  • Derailleur hanger: Universal Derailleur Hanger (UDH), replaceable.
  • Brake fitment: Flat Mount Disc.
  • Cable routing: fully internal.
  • Max tire clearance (single chainring): up to 700×53 mm or 650Bx2.1".

The Altera G21 also features:

  • 4 bottle mounts,
  • mudguard compatibility,
  • cargo rack compatibility,
  • internal storage compartments in the top tube and down tube (with an integrated bag).

Maximum rider weight is rated at 125 kg.
