This kit allows the conversion of a 3-fold to 2-fold crank.
The titanium chainrings Carbon Ti are especially recommended for frequent travelers. The titanium alloy has a significantly higher wear resistance than the aluminum alloys often used ordinary chainrings. To ensure a precise and smooth shifting shift aids were milled. When shifting the chain is also supported by the glued plastic bodies from durable Delrin.
The chainrings are 100% manufactured in Italy!
To convert a conventional 3-crank is simply the large sheet attached to the middle position and the Small to the innermost position. It is possible to conventional 3-speed front derailleur and shifter to continue using it. With the help of the adjustment of the derailleur that no longer existing third position can be blocked.
With very wide chainstays it may happen that the big blade grinds on the chain stay. This problem can be solved with the X-Line Adapter from Carbon Ti. This offset the large chainring minimal outward. It is also possible to contribute to wide chainstays to mount a slightly smaller 40s sheet.
Advantages of 2-speed cranksets:
- The weight savings compared to a normal XT crankset is approximately 75 gr.
- The annoying switching of three chainrings falls away (better transition utilization)
- With the large chainring can all gears ride on the rear sprocket
