For 2002<br />

Our steel frame geometry<br />

remain unchanged<br />

from 2001.<br />

Geometry<br />

These bikes have angles<br />

and top tube lengths that<br />

put a rider in a more<br />

upright position. The<br />

angles have been adjusted<br />

to make the bike stable<br />

with the more recreational<br />

weight distribution (as<br />

opposed to the forward,<br />

aggressive position of racing<br />

bikes).<br />

Ride<br />

Although our steel<br />

mountain bikes are more<br />

upright than our racing<br />

bikes, it’s a subtle difference.<br />

These are not cruisers<br />

or hybrids, but simply<br />

more comfortable<br />

mountain bikes. The more<br />

upright position allows a stable ride, and easier balance<br />

for the more casual rider. Extremely technical terrain<br />

may be more of a challenge, but this bike wasn’t<br />

designed for the rider who spends the majority of their<br />

time attacking Moab slickrock or slippery Mt. Snow<br />

singletrack roots. By contrast, these bikes make cruising<br />

dirt roads and doubletrack fun and easy.<br />

Frame details<br />

The advantage of Cro-Moly steel is higher tensile<br />

strength and fatigue resistance; it’s no more rigid than<br />

good hi-tensile steel. For this reason, we’ve only used<br />

Cro-Moly in the seat tube, which can see lots of flexing<br />

as the seatpost quick release is used. For the rest of the<br />

bike, we’ve focused on providing the best ride for the<br />

cost. By carefully designing the frame geometry, tubing<br />

wall thicknesses, and tubing diameters, we’ve managed<br />

to create a frame that rides like those costing much<br />

more. This allows riders a viable high quality alternative<br />

to chain store bikes which don’t ride nearly as well.<br />

Full top tube cable routing keeps the cables out of the<br />

muck for friction free shifting and braking.<br />

The rear dropouts on these frames are forged steel.<br />

Forging provides the highest structural integrity, which<br />

is very important for keeping the dropouts in alignment<br />

with the rest of the frame. If they are not in alignment,<br />

premature wear of hub bearings may result, along with<br />

imprecise shifting of the rear derailleur.<br />

Although designed for casual riding, we see folks<br />

riding these bikes on long dirt rides, and even road centuries.<br />

To keep you hydrated and happy, our steel bikes<br />

have 2 water bottle mounts, except the 13, 16.5”, and<br />

Ladies frames. These frames size do not have enough<br />

seat tube to allow a water bottle mount to be used.<br />
