I am a muppet......

I buy kit and can never fix it or sort fairly minor problems. The CX racing season is upon me so I am after advice from you lovely folks on some changes.

I have been running rotor agilis cranks with Q rings on a kinesis csix2. I no longer like my q rings and am after some advice; can I just change the chainrings to normal ones, if so, any advice on compatible lightweight rings or should I just swap the lot for a rival 22 chainset? It's a bb30 bottom bracket by the way.

Secondly I run two sets of wheels, kysriums sscsl tubs and open pros laced to 105 hubs. My rear derailleur rubs on the spokes of my open pros, are the wheels different widths or something?

Thank you all

    Re: chainset. Yes, you can change the rings. You will need to: make sure you buy rings with the right BCD (bolt circle diameter, either 110mm or 130mm and will be written on the current rings) and the right number of teeth - usually 46/36 for 'cross; make sure that either your existing chainring bolts will work with your new rings, or get new chainring bolts (and some Loctite and a torque wrench, preferably, either way); move your front derailleur down so that the bottom of the cage is 2mm above the largest tooth on the large chainring once you have the new chainrings fitted.

    Re: wheels. Entirely possible. Sounds like your high limit screw is too far out, so the rear derailleur can move too far in. You need to adjust this so that the jockey wheels are vertically aligned below the largest cog when the bike's in bottom gear.
