The Tune Cappy is an excellent alternative to standard seat mast heads in the emerging market of ISP (integrated seat post) frames. The Cappy features a wider range of adjustment than most other options, and is available in Tune's full line of vibrant anodized colors.
The Tune Cappy is designed and manufactured in Germany to the highest quality standards. Tune has set no rider weight limit for this seat mast head, and it is covered under a two year warranty.
To ensure proper fit, please take note of the following dimensions when ordering:
minimum insertion: 3.5 cm
minimum insertion line to center of saddle rails: 3.5 cm
adjustment range: 2.0 cm
Detailed installation instructions are provided with the Cappy - 4 and 5 mm hex wrenches are required for proper installation. We also strongly recommend the use of a torque wrench; the m5 main clamping bolt should be secured to 4.0-5.5 Nm, and the m6 yoke bolts should be tightened to 5.0-6.0 Nm. When using saddles with carbon rails, the edges of the rail contact areas should be manually.
