System
Design Proposal

2. Needs Addressed
• Laces hard to tie when
under high tension
• Difficult to get correct
lace tension
• Cold hands make tying
even harder
• Frequent adjustment not
practical with tied
laces – especially when
using double-knots

3. System Description
Laces slide freely
in one direction
and lock in groove
when released
Left lace in Right lace in
bottom groove top groove

4. Usage
• Start day—loose laces for
increased comfort
• Top of run—tighten laces to
optimum riding tension (with
gloves on!)
• When needed—release laces and
adjust tension
• Bottom of run—loosen laces for
chair ride or hiking
