That's what I do. Works well.happygofun said:when I raced 1x8 gears in cross I used a front der. sans cable and set it as low as posible to the chain. I found a sweet spot where it wouldn't rub regardless of the chainline.
This kept the chain in place on rough decents and with repeated drops after barriers (I know shouldn't drop but 'place' the bike down but am still working on technique).
Not the most elegant to be sure but... it worked and was cheap as I had a spare front der.
Longer cage = longer lever, and in this application, the chain is the force acting against the spring tensioning the derailleur cage.jmw said:I don't understand why the short cage der is recommended...seems to me that the long cage would take more slack from the chain, more leverage to pull chain tighter, right?
longer cage=longer lever
