Overview
The Syndyt 205 Pro sits between Syndyt's Junior and Pro 2XL frames, with a 20.5 inch top tube built from the same triple-butted 6061-T6 aluminum.
At 3.99 lbs it uses the tapered 42/52 head tube and B52 oversized bottom bracket found on the Pro 2XL frame, along with support for 10, 15 or 20mm rear hubs and built-in chain tensioners. Since Syndyt sells this size alongside the Junior and Pro 2XL frames in the same range, top tube length is the main spec separating the three. No description copy or reviews are included in this listing.
