• Headset spacers: I've always used Hope Head Doctor and second-hand Chris King, as they're both machined well and have almost zero deviation from their intended shape.

    I now need to create an exact stack height which can't be done using Hope's limited range of sizes, I can't find any suitable Chris Kings for sale, and I'm loathe to randomly buy a selection only to find they're on the piss.

    Which reasonably-priced 1-1/8" spacers with 35mm outer diameter are well-made enough to be true around their rims, and come in 2/3/6/12mm heights?
