No offense, but your current bike could be a Riv poster child for the 'racer look' vs the 'Riv look', bars much lower than saddle vs bars at or above saddle height (<= 2" above).
The Sam uses a quill stem, so you can adjust the quill height. To replicate the fit on your existing bike, get a quill stem of approximately 150mm quill length and a stem length of the your current threadless stem adjusted for the increased seat tube setback of the Sam vs current frame Saddle Height * (cos(STA current) - cos(STA sam)), Probaly 3cm based on a 71cm SH and a 74° STAcurrent (Sam STA is 71.5°). For a higher bar height, you'll need a quill length of 180mm or 225mm. Moving the bars up also brings them back by a few mm, use the above equation and substitute 'difference in quill length' for 'saddle height' Your frame seems to be small or medium, so a 180 or 225mm quill may NOT be able to be inserted into the head tube/steerer tube far enough to get a 'low' bar height. This has happened to people before, since Riv recommends longer quills, assuming you'll use the longer quill to extend the bar height and stuff it into a short head tube. Dont wrap the bars until you are done getting the bars where you want. John Hawrylak Woodstown NJ PS the Seat Tube Setback is greater with the Sam vs current bike, since the Sam STA is smaller (71.5° vs probably 74° on current bike). This affects the distance from the saddle to bars using Stack and Reach by themselves On Monday, January 9, 2023 at 9:42:15 AM UTC-5 Davey Two Shoes wrote: > Hi Everyone, > I'm building up a Sam Hillborne and this is my first Riv build.
