Serpent SRX2 MH 3 Gear Idler Gear (2) (31T)
Looking for a replacement Idler for your B5/B5m? This unit will work, although it is 1mm narrower than stock. So two .5mm shims on either side will make it fit. A better fit for the B5 is the Custom Works idler csw4480. I see these are available in aluminum from serpent as well, so that's an interesting option.
