Miter Sheet Translation ?
Looking at a custom BW and am torn about how it has a level bar drop with my usual saddle height and a short heat tube.
Can anyone generate a stack and reach based on this miter sheet ? I assume it’s to scale so CAD or something could accomplish this ? https://uploads.tapatalk-cdn.com/202...0df1989d7f.jpg |
I use bikegeocalc.com for these tasks.
|
I get a Reach of 359.6mm and a Stack of 509.4mm (based on the assumption of a 10mm lower headset stack). Effective top tube length 515.3mm
But someone should double check my numbers. |

deleted, 448.5 dim is what I needed.

If you print it out 100% portrait orientation it is almost exactly 1:100 scale. Incredible, or perhaps the program was designed as such. Either way I am impressed.

ETT 555
Stack 565 Reach 387 This is to the top of the headtube and not the hypothetical headset cup ETA: Please see post #30, the drawing displays only the bare headtube with no measurements for estimated headset cup thickness. |

Crap! I got Stack calculation wrong, too! (But the reach should be right) Stack should be 547.5 x sine( 78 - 73 ) + 532.5mm x sine( 73 ) = 557.0mm Reach should be 547.5mm x cosine ( 78 - 73 ) - 532.5mm x cosine( 73 ) = 389.7mm |
Thanks everyone,
Maybe I’ll just average the results and hope for the best ? :0 Measurements from seller: TT: 54.5cm (CTC) ST: 51.5cm (but compact geo) CTC Crank to Saddle: 728mm w/ estimated level bars HT: 14cm Stem spacers: 20mm + 2.5mm on top Stem length: 90mm Chainstay: 430mm |
Well don't do that the numbers Mark McM gave you are way wrong
Measuring in high resolution with Gimp I get ETT 559 Stack 563 Reach 388 |
OK, just saw the 448.5 dim:
eff TT 559.6 Stack 581.8 Reach 381.7 (stack and reach being to the top center the HT) |
I only have my cheapie travel calipers but they seem to agree with the pixels. Please excuse the parallax.

You guys are the best.

The most important consideration for Breadwinners is; what livery? Some of the paint options are excellent and some are not so great.
I saw this specific bike in person and was taken aback by how good it looked IRL. https://bikepacking.com/wp-content/u...1-1200x800.jpg |
