Grand Cru 50.4 BCD Crankset MK II (46/30T) $200
These cranks offer tremendous versatility (chain rings from 28t to 62t fit). They are also light and have narrow Q-factors, or tread. Cold forged 7075 aluminum alloy. Fits square taper BBs. The rings have modern shifting aids. 46/30; 5-10 speed compatible. All bolts/nuts are Allen head. Shifts well with double or triple front derailleurs. About bottom brackets: Most road frames use a 118mm BB. Bikes with 135mm spacing and room for big tires may need a 122 BB with a spacer. Available in 165mm, 170mm, and 175mm lengths.
Classic 50.4 BCD cranks, like the TA, Stronglight 49D, and others, are still sought after by randonneurs and cyclo-tourists. These cranks offer tremendous versatility (chain rings from 28t to 62t fit). They are also light and have narrow Q-factors, or tread

PUT ON GIANT REVOLT (2015 Revolt 1)
Would need to buy the VO crank ($200) and get Tiagra 4700 Derailleur ($37) to make it work. 30/46T X 11-34 = 24.2 to 114.9 GI
Shifters: R460 (Can shift 11-34)
Front Derailleur: R4600 (Max diff = 16T)
Rear Derailleur: R350 (11-34; Chainwrap = 35)
(46-30 = 16) + (34 - 11 = 23) = Total = 39
Would need a derailleur to handle this: Shimano Tiagra 4700 1GS 0 Speed Rear Mech $32.99 - $36.99; Compatible with up to a 34T cassette. Maximum Front Difference: 16T (front double) / 20T (front triple). Total Capacity 39T (front double) / 41T (front triple)
