Prologue MD-20
18mm Profile Alloy Clincher 26" XC Wheelset
With the recent restrictions, many people have pulled their old bikes out of mothballs and freshened the old steed up to get a bit of fresh air and exercise. However, with shifting standards, many older frames built for 26" wheels have no more options available. The MD-20 is perfect for this and features hand-built quality at a price point never before seen. With these wheels, you can experience the responsiveness, efficiency, confidence and power transfer of a hand-built wheel at cheaper than many machine-built wheels can be found. The MD-20 road wheel is differentiated from its sibling by using loose ball bearings and is only available as a 26" variant with XC-type rim dimensions.
