Piano High Direct Mount (HDM) – chain guide (28-36T)
Key features
- 1x chain guide for S3/e-type frame standard
- Compatible with 30–36T chainrings, including oval
- Chainline adjustment via included distance washers
- No crankset removal required — installation in approx. 5 minutes
- Includes extra guide plates for oval chainrings
- Suitable for enduro, XC, AM and cyclocross
- Guide plates moulded from glass-filled polyamide (Ultramid)
- Weight: 25 g
Description
The Piano S3/e-type was developed for frames where ISCG05 is not available and the S3 or e-type direct mount standard is used instead. Like the ISCG05 version, it is designed to complement a narrow-wide chainring and clutch derailleur on trails where that combination alone is not sufficient.
Mounts directly to the S3/e-type frame standard without removing the crankset. Chainline is adjusted using the included distance washers inserted between the tensioner and the frame. Guide plates are moulded from glass-filled polyamide (Ultramid) — a PA6 reinforced with glass fibre, chosen for its higher stiffness and dimensional stability compared to standard polyamide. An additional set of guide plates for oval chainrings is included.
Compatibility
Compatible with S3/e-type frame standards. Supports 30–36T chainrings, including oval.
