Hey guys, I'm wanting to stick a newer 26mm front wheel on a 98 640a with a 17 mm axle. Does anyone make a 17 to 26mm spacer? Can I use a bigger bearing, maybe one that has an inner diameter of 20mm, so I can use a 17 to 20 mm spacer? Or is there a way to bump up my axle size without a new front end? Weighing my options here. Thanks for any input!
