I've got a Maclaren Triumph stroller, which is probably about 3 or 4 years old. I hit one of the wheel sets with my car, so I need to replace one set of wheels. It appears simple to just snap a new wheel set on, but I can't locate a set. Can you help?

Just got me new wheels form ebay, click on link below!. Please check wheel diameter, unworn is about 125mm, axle size ( size of metal rod that goes through both wheel, access by removing the end cap, just pry open slowly.. measure )..should be 6mm or 8mm. using the link below buy online on ebay. under maclaren wheels or click link below

They about £22 for set of 4 wheels normally you replace all 4 back ones! come with end clip. remove them with a good set of pliers, they can be a pain, get help! Replace with new once, get them back is easier but again if not sure ..get help! as your child is on it and you do not wanna them falling off while crossing the streets ... their safety lie in your hands now! good wheeling
