I have a direct mount front derailleur on my TT bike and at the moment I have a non-round ring running 52 teeth. This BARELY fits at the point of maximum adjusted diameter... (relatively 54/55 teeth). Problem: I want a bigger front chainring... and it will be non-round. It's a personal preference based on my knees, hips, crank lengths, experience, marketing hype and placebo effect... So no opinions on this - thanks. None of the non-rounds fit - and I believe I need an adjuster like the images. This spacer moves the FD backwards, and thus I can get a bigger blade on. I can find some online in the UK but for GBP30... plus shipping, postal inefficiencies etc... I have contacted Rotor directly for the part - no reply yet, but I fear this part may be near R1,000. Any alternative or 'Ghetto' solutions?
