That's interesting. How come you reckon none of them are fine? Genuinely curious.

For general maintenance and cleaning, your 99.9% stuff will do just fine. If you really wanted you could buy some bike branded stuff like Muc-Off disc brake cleaner which comes as an aerosol. Pretty much the exact same thing.

Industrial isopropyl is absolutely fine for rotors and pads. I've used the 70% stuff and 99% stuff in the past with good results. Don't forget to clean the inside edges of the cut-outs in the rotor as dirt/contaminants can stay trapped in those pockets. For contaminated pads, I've found that just using alcohol is not enough to get rid of brake squeal if it's deeply contaminated. Use sandpaper, then wipe away with alcohol, repeat if necessary. Boil the pads or blowtorch 'em as a last resort. Contaminated disc pads are trickier to 'save' than rotors, usually. Sometimes even all these steps are not enough to save disc pads from howling, in which case it's new pads time.

It's interesting that the Guilty has a wider than normal BB. From the sounds of it, it has an 83mm shell like DH frames, correct me if I'm wrong. I wonder why? Maybe a wider crankset/spindle improves stability kinda like how wider rims offer more sidewall support on off-camber surfaces. Bonz cranks are on the shopping list - really curious how they will work out with a fixed 18t sprocket on a 1x10/11/12 drivetrain. Hopefully the non-drive crank won't have any issues with some blue Loctite on the pinch bolt thread, we'll see. If it has issues then I'll try your Shimano method For your custom Marino, is the mech hanger gonna be replaceable on the vertical dropouts or is it an integrated hanger like on old-school 90's steel frames? Looking forward to seeing updates!

Thanks for that dude. Yeah did wonder how everything was held in place seeing as there's no threads for a lockring or anything. As the preload from the compression bolt is about 1nm or less - is there play in the system between the freewheel/sprocket and bash moving under torque? With the single pinch bolt, did that just end up coming loose all the time leading to crank on spindle play or did you find another issue with it?

How wide is the Bonz spindle compared to the Shimano's 68/73mm MTB spindles? Have wondered if it's possible to fit the Bonz crankset onto an MTB frame with a 73mm wide bottom bracket.
