Silvio Chainstay Extension
When the Silvio is adjusted to a taller rider the crank gets lower to the ground, as it rotates forward. To compensate, we have produced 100mm and 150mm extentions to the chainstay. When these are used, the chain must be lengthened by 200mm and 300mm respectively. The extension does not affect your FD mounting at all, and the FD stalk pictured from a Silvio 1.5 is not included and would not fit a Silvio 1.0 anyhow.
PLEASE SPECIFY SIZE IN YOUR ORDER COMMENTS WHEN ORDERING. 100mm OR 150mm.
As a guide, if you are 180cm tall, take the 100mm, if you are 190cm tall, take the 150mm. Otherwise, you will probably be happy with the standard chainstay length.
If you are adding a Chainstay Extension to your Silvio, is possible to estimate the expected new BB height like this:
o place a rod vertically at the BB;
o measure distance from axle to BB, which will be 430mm;
o take a measure 530mm from the axle to the rod, mark position on rod and see how high this is.
o repeat for 580mm
