I hear ya, I just ordered the Bikespeed-RS dongle for my Sduro Trekking. I wasn't sure I would need a higher stop speed than 20mph, but I definitely noticed the limitation on today's ride. I'm not sure I'll be pegging 28 every day, but I could've used an extra 3 or 4 today. I'm not going to mess around with moving sensors and getting incorrect readings, I'm doing it right!
