Hi, looking to buy a pair of 650b rims for xc only. I weigh 70 kg. are the 330gram rims ready for sale ? Price please. Can you supply a complete wheel set with above rims, dt Swiss 240 hubs and xc ray spokes or the equiverlent spoke. Price please. Many thanks Russelll

Light-Bicycle 2014/08/05

Hi Russell, Thanks for your inquiry. We can manufacture the hookless 30mm wide 650B XC rims for you. Hookless is more durable. Please find attached cross-section drawing. RM650BC02 (30mm wide 650B XC rim) hookless: 370 /-15g, USD163/pcs Please note that the weight we manufacture is 370 /-15g, no 330g. For rim weave, do you prefer 3k, 12k or UD? Matte or glossy? 32H? The shipping cost is USD50 for two rims to UK by EMS. We also can build the wheelset with above rims for you. But we only have Novatec & Hope hubs currently, no DT Swiss hubs. Is that ok for you? What hub axle size do you like for front & rear? Standard qr or thru axle? Spokes: There is only black Pillar Aero X-TRA 1420 aero, no Sapim CX-ray spoke. Do you like it? The spoke weight is quite the same as Sapim CX-ray spokes. Nipples: Pillar PT 734, which color do you like? Wheelset price (with Novatec hubs): USD584/pair Wheelset price (with Hope hubs): USD799/pair Thanks, Light-bicycle

ren 2012/08/31

I would recommend the same dimensions you are doing for you 26inch wheels. The market is trending to 5.5-6 inch suspension bikes for 27.5. These bicycle types typically run large volume 2.35-2.5 inch tires. A 21mm internal width is great for a trial bike but not for an aggressive rider. I also would recommend a deeper dish on the mountain rim so we can run shorter spokes.

Support 2012/09/01

hello Ren, Thanks for your suggestion. The 650b rim has already been designed. It is the same outwidth and inner width as 26er wide rim. Is that ok for you? Thanks, Light-bicyle
