It is usually integrated chain tensioners and headset, sealed bottom bracket, tapered head tube, 31.8mm seatpost clamp, and a 68mm English threaded bottom bracket.

Aluminum bike frames will have double-butted and triple-butted tubes that experience different thicknesses, allowing the frame to maintain high-stress points on the end of the tubes with no need additional weight during the middle. Double-butted frames add extra subject matter at each and every end of the tube where additional strength is needed. Triple-butted frames use the similar process, but reduces weight within the center much more.
Celebrating bicycling for all that it offers, Pure Cycles offers a lot of frame, geometry, and gearing options in addition to a cornucopia of compatible accessories, including different styles of handlebars, saddles, water bottle cages, foot straps, and more.
