Does anybody on here have a dolan adx?

I picked one up off eBay a couple of weeks ago and the frame rides really well I’m very impressed but I’m having trouble fitting a mudgaurd to the rear, there just doesn’t seem to be enough clearance, I’ve spoke to dolan and they suggested dual pivot calipers which I have now fitted but I’m still struggling it seems the brake bridge is too low, the guards I tried are a little tired and I’ve just taken them off my kinesis racelight t, I’m going to try some sks bluemels, which is what most people seem to use.

So does anybody have one of these and if so which guards have you got and is there much clearance?

Thanks
