This QR type hub is ideally suited to 20” wheel at 6V3W output or 26”/700C wheel at 6V2.4W output. It is perfect for rim brake.
The model is designed for 20” wheel at a 6V3W rating. It is also ready for use with 26”/700C wheel at 6V2.4W outputs. After the speed reaches 15km/h, SV-8 (for 26”/700C) output is almost the same as 6V3W hub. Therefore, SV-8 offers sufficient power for racers during the races.
