This wheel has a 20mm round groove with a 22mm opening at the rim, so it needs a 20mm diameter ground track and will not run on an inverted-V ground track or flat bar. For an inverted-V ground track, choose the V groove version, which has a 16mm opening.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAgainst the larger size.\u003c\/strong\u003e The 100mm wheel measures 98mm rather than 78mm. Its housing is 151mm overall and 32mm wide against 135mm and 33mm here, with its holes on 126mm centres rather than 110mm. Both show 27mm of wheel below the tabs, so the difference is inside the rail: this wheel rises about 51mm above them and the 100mm wheel about 71mm.
