saddle-in aka :(Ln is a rider-bicycle coupling that creates an advantage by locking the pelvis in place with a tailbone counterforce, resulting in more power and speed along with ideal riding form, optimized aerodynamics, and back pain relief…
go faster, guaranteed.
a cyclist mechanical advantage that provides a counterforce to each pedal stroke … go ahead, take advantage!
it locks your pelvis in place with a tailbone counterforce. it is like riding while in a leg press or on a recumbent bike… we've got your back!
power, optimized aerodynamics & form, back pain relief, and, of course, go really fast!
though it is advised to begin in the middle of the top tube, the ideal location of the hook is a matter of preference and of top tube angle.
• for flat top tubes, hook placement is 1/2 the distance from seat tube to handlebars.
• for angled top tubes, hook placement is 3/4 the distance from seat tube to handlebars.
though known as the tailbone harness, the ideal location of the counterforce and placement of the logo on the harness is on the sacrum(or sacroiliac position) per the image below…
note the skeletal structure and positioning above the tailbone.
• feeling muscles not felt before
by locking the pelvis in place and activating glutes with proper joint angles, it is expected that the entire lower body power production system is engaged differently and more effectively.
• initial awkwardness
saddle-in is a different way of riding on the upright and a period of adjustment is purposeful… think of saddle-in as having someone pushing your back into each stroke of the pedal.
• perineum pressure
as saddle-in pulls you into your crank and into your saddle, there may be increased perineum(soft tissue) pressure… as such and for all cyclists with or w/o saddle-in, it is advisable to use a saddle offering perineum relief.
"scooting back or forward in the saddle" is a matter of adjusting tether or riding with a more aerodynamic position which will enable individual comfort in a rider's fore-aft saddle postitioning...
the intention of :(Ln is to ride seated with more power and speed than that achieved standing…we appreciate this is a significant paradigm shift… just saddle-in and ride seated…
note that decoupling will occur with out-of-saddle forward positioning and when standing up on pedals… again, :(Ln is designed for fast coupling/fast decoupling (quick release), for performance & safety.
testing & field reports have repeatedly demonstrated higher efficiency, power output, and speed when seated in saddle-in as opposed to standing without...
riders report that more experience with saddle-in leads to staying in the saddle more and more efficient coupling and de-coupling...
faster in/out of harness
loosen/tighten just one side and always get-in/out of the harness with other 2 adjustments in-tact. leave t-string in position &/or right or left side of harness webbing… riders report they maintain 2 of the 3 adjustments fixed when getting in/out of the harness…
fast couple-in & couple-out
saddle-in is designed for
fast in/out & safety…
• to couple-in faster; lean-in with left hand, practice, and goreallyfast!.
yeah, we know "you don't wear no girdle or t-string!"…
however, optimum performance dictates that the t-string is a necessary component to ensure the counterforce is located/optimized "low & on the sacrum" (per above harness location)
strap-in & goreallyfast!
• adjust hook location fore & aft
• adjust overall bike fit
• adjust harness fit
• adjust harness tautness
• adjust tether tautness
