after some help with post mount brake adaptors...
How do I know what the default disk size the frame is designed for (without needing an adaptor)?
Much as I love the Shan's artwork, a discounted Ragley Blue Pig frame lured me to choose that...
The spec/info on the Ragley site doesn't state a stock disk size, but looking at the images of their complete build (
http://ragleybikes.com/products/blue-pig-complete-bike-2019/ ) it looks like a spacer on the frame's post mount (and it mentions 180mm brakes). So... I'm assuming the frame is 160mm disk and thus I will want a 10mm spacer for 180 disks. Is there a dimension to measure to check (before trying to fit the brakes, as I don't have them yet)?
Also, looking at the adaptors, why are there different front and rear spacers? Looking around various bike websites, the front seem more horizontal and the rear seem to be angled. But, the image on the Ragley website looks flat. Erm... Surely the distance between the holes is the same fork or frame, so why the different shape spacers?
