TRP R960, which I'm loathed to replace because they're super light and cost someone lots of money. The pads are fairly worn now and it's still super tight. I mean, I've ridden them like this for over a year, just trying to avoid buying fancy wheels that won't fit.
Different pads can help, Swissstop have a new wide rims pads that allow more clearance (but less material).
What brakes is it? Modern Shimano brakes (says 5800) can give more clearance as it's better designed for wider rims.
