grabcad

This is the first in the world model of bicycle frame ready for 3D printing in titanium. When prices of 3D printers will drop and build volume will increase, just download, print and enjoy riding! Frame specs: - 29er hardtail, M size - exclusively for 1-9, 1-10, 1-11 drive train systems (no front derailleur mount), preferably SRAM XX1 - 1.5" head tube, preferably for Lefty 90mm - 83 mm BB for PressFit 30 - 156 Q-factor crank - max. 38T front chainring (assuming 49mm chain line) - 2.35" tire clerance - Syntace X-12 dropouts - 160 mm post mount, direct mount disc brake - 34.9 mm seat clamp - 31.8 mm seat post - weight: approx 1.28 kg Restrictions: - should be printed only in titanium alloys (preferably grade 5) as the project was optimized for titanium alloys. No static analysis was performed for other materials - please respect any licensing agreements (e.g. the company Syntace requires signing an agreement regarding manufacturing frames with their dropouts) - you need to make bottle cage threads yourself (only holes are printed) due to printing technology limitations - there is no cable routing at this moment - use your drill or zippers:) - there is still a lot of space for improvement, e.g more detailed wall thickness modification on the basis of FEA results Model: The model was made in SolidWorks and Rhino, with use of T-Splines in both. FEA static structural analysis was performed in Ansys Author: pawel.alexander@gmail.com
