Giant Revolt X Advanced Pro

Revolt X Advanced Pro 2 (2024), Giant UK spec: Handlebar "Giant Contact SL XR D-Fuse, 31.8mm S:44cm, M:46cm, M/L:46cm, L:48cm, XL:48cm"; Stem "Giant Contact, 8-degree S:50mm, M:60mm, M/L:70mm, L:70mm, XL:80mm" (stem angle 8 degrees as printed; note the geometry table's Stem Length row prints 60/70/80/80/90 mm for S-XL, 10 mm longer than the spec line, and its Handlebar Width row 440/460/460/480/480 mm). Fork "RockShox Rudy XPLR, 40mm, cartridge damper12x100mm thru-axle" (a 40 mm travel suspension fork). Seatpost "Post Moderne, dropper, 30.9mm with 30mm of suspension ... 415mm / 100mm drop" on every size.

Five sizes S, M, M/L (Giant's table header prints ML), L, XL; the spec Sizes line agrees. The frame has a two-position flip chip dropout ("adjusts the wheelbase short for quicker handling, or long for improved stability at speed. The long setting also allows for larger diameter tyres up to 53mm"; "53mm max tyre size in "long" flip chip position, 45mm max tyre size in "short" flip chip position"). FLIP CHIP: in rows B, E, G, H, I, J and M Giant prints two values per cell separated by a divider, the second marked in the page markup as the "highversion" (the page gives the two no text label). The first values are the short setting (425 mm chainstay) and are the ones stored here; the second, long setting values are: seat angle S 73.4, M 73.4, ML 72.9, L 72.9, XL 72.9; head angle S 70.9, M 71.4, ML 71.9, L 71.9, XL 71.9; trail S 80.3, M 76.8, ML 73.4, L 73.4, XL 73.4; wheelbase S 1034, M 1036, ML 1041, L 1051, XL 1067; chainstay 435 all sizes; BB drop 69 all sizes; standover S 743, M 761, ML 778, L 796, XL 814. Stack, reach, top tube, head tube and seat tube are single values. Bike Insights files the same two settings as the MY2023 Revolt X Advanced Pro "Short Flip Chip" and "Long Flip Chip". The fork is a 40 mm RockShox Rudy XPLR; Giant does not say whether the table is drawn at sag. Giant's row keys: A Seat Tube Length, B Seat Tube Angle, C Top Tube Length (recorded as top_tube_effective), D Head Tube Length, E Head Tube Angle, F Fork Rake (fork_offset), G Trail (printed, kept), H Wheelbase, I Chain Stay Length, J Bottom Bracket Drop, K Stack, L Reach, M Stand Over Height, N Handlebar Width, O Stem Length, P Crank Length 170/172.5/172.5/175/175, Q Wheel Size printed "700x 42C" on every size although the stock tyre is 700x45c. Giant does not say whether the seat angle is effective or actual (null), does not publish front centre (null) and does not state the stack datum (null). PROBABLE MAKER TYPO, FLAGGED NOT CHANGED: row F prints Fork Rake 50 mm on every size, but Giant's own printed short-setting trail (76.9/73.5/70.1) is what a 45 mm offset gives on these head angles with a 45 mm tyre (about 75 to 77 mm on S), while 50 mm gives about 7 mm less (69.7/66.4/63.1); Bike Insights records 45 (not checked against RockShox). The 50 is stored as printed.
