    My goal is to transform my 24spd (3x8) into an 8spd (1x8) + RaceFace Bash Ring..

    I bought a BlackSpire Mono Veloce chainring for my single ring.

    The current crankset that I have is the stock Truvativ X-Forge.

    Now, my confusion is the lining up of the holes for the ring, bahguard and crankarm. Um, they dont match! The BlackSpire ring and RaceFace bash guard have matching holes but I dont know how they will attach to my current crank arm.

    I wont be keeping any of my current rings so how is the crank arm going to attach to the new ring and the new bash guard??? :confused:

    Simple answer it won't. The bolt circle holes have to match. What you could do is Dremel the teeth off the big ring into a bash guard as you save for a properly matched crankset

    Yeah, after staring at it for hours yesterday I realized that it wont work. So what exactly does BCD mean? I know of the different sizes and it looks like mine is 104.

    I think I need to get a new BB and crankset if I want this single ring setup to work. Apparantly square-tapered BB's and my style rings are outdated.

    The two parts that I already have are the BlackSpire Mono Veloce ring and the RaceFace Bash Guard.

    Before I get a new crankset and BB I want to make sure that all four parts will work together. The crankset is going to be the FSA X-Drive and the BB is gong to be the RaceFace SRX.. Both are ISIS splined which Im assuming is the only thing that I need to match up?

    So is ISIS Drive the same as ISIS Splined?

    Last question...does it matter what size ring bolts I get? Since Ill have just the one ring and the bash guard, will 9mm bolts be long enough?

    Something like this:

    Standard sized bolts should work. Try asking in the mechanics forum, might get more hits.
