Revision as of 17:47, 13 August 2007

Riding mountain bikes in Marin is awsome. The climbs are big enough to be real and the trails are very challenging (especially at speed). Hardtails make everything really fun. A long travel suspension bike is pretty much wasted on the riding here and almost makes the trails boring. About 3-4" of rear travel would be perfect but this is commercially unavailable and I'm not ready to do suspension bikes yet. My aluminum welding needs to get a bit better.

A long travel fork is always a charm, but you can't just slap one on these into any hardtail frame. This frame is going to be designed around the longer 130mm and 140mm forks with traditional quick release dropouts.

The Fork

This bike is being designed for use with a Fox Float 140 (140mm) or a Rock Shox Revelation 426 Dual-Air (130mm)

Both forks have a 39mm offset and relatively the same axle to crown dimention (fully extended) of 510.9mm for the Float 140 and 508mm for the Revelation. Either fork should produce the same feel with the 71 degree head angle, 70mm of mechanical trail.

The Tubes

I'm keeping this bike cheap in case the geometry doesn't work out quite right.

  • Down Tube - Nova 29er DT 35 x 8/5/8 $16.20
  • Seat Tube - Columbus ZONA 28.6 X 8/6 X 635 $22.51
  • Top Tube - Columbus NEURON 28.6 X 7/5/7 TT $20.00
  • Chain Stays - NOVA CRMO 22MM OVAL 425 - 12 DEGREE BEND $18.50
  • Seat Stays - DEDACCIAI 12.5 16mm X 0.6 SINGLE TAPER 560 $18.71

Fork Clearance

This bike was designed to give full clearance for a spinning fork.
