Recently cracked the rim on a Hollowgram HG35 rear wheel by riding into a pothole and need a replacement! Unfortunately, it seems pretty impossible to get hold of these wheels in the UK. I’ve been very happy with them and they’ve served me well for three years, particularly in terms of bearing life.
You may consider a known brand Chinese wheelset. You will have more choice and up to date rim profiles. Light Bicycle and Farsports would definitely fill the bill as would a number of other brands.
