Excellent Value For Money Conversion
Posted on 19th, July 2017 about Raptor Chainring 110BCD Asymetric OVAL - Narrow Wide by S. Churchman
Bought this for my cross bike to convert to 1x. For correct chainline I fitted it inboard of the 105 5800 crank and fitted a spacer to the drive side BB to get correct chainline. If you fit it outboard (where the big ring is) chainline is compromised and when in the lowest gear you get chain drop. The oval works well for me having used one on the MTB. Teamed with Shimano SLX 10spd clutch mech no chain drops so far. Good cheap way to see if you can convert to and live with 1x. Note: I use a Jtek Shiftmate 6 to make the 105 road levers work with Dyna-Sys rear mech.
