74 degree seat, 70 head angle. 405mm chainstays, 540mm front center. 150mm head tube with 25mm upper headtube extension. Reach calc comes in at 314mm, stack 548mm. ETT (Taiwan) is 471mm. 155mm maximum crank arm length. Front derailleur spec'd for a maximum 46 tooth chainring. Stem spec: 90mm -6 degree, 70mm reach bars. Addition of heat tube extensions top and bottom, Might need to be reworked. This was done to increase stack while avoid adding 40 mm steer spacers or avoid using a tall riser style stem. 650bx28 tires with room for a 650bx 35. The extra space should permit fenders to slip into place with 28. Wider rubber, no fender is the rule here. Unsure if trail of 69mm, paired with 45mm rake is sufficient for neutral handling? Professional guidance is welcome! Many a small frame's offer bottle bosses that are poorly executed. Boss placement will probably need extra attention to get them just right. Desire is to get frame's derailleur clamp band to fall in between my seat tube bottle bosses. When placement is perfect, two large bottles do fit, so hopefully that can be made to happen with this design. Fizik Argo Tempo R3 specified in design is a short nose saddle, 160mm width, 255mm in length. Shoe size 37 euro, SPD SH-56 cleats are set ball of foot, slightly to mid foot position.
