Mass market ideas on fitting don't cut it on the 29er! The wheels are larger and the real concern is getting the saddle to top of handlebars correct. For example the riser bars really throw things off.
Controversial career
Lance Armstrong has announced his retirement. He become increasingly mired in controversy. He was to take part in a number of events on the US calendar in 2011?
Was Contador the straw that broke Armstrongs back?
Armstrong revealed his decision in an interview with The Associated Press on Wednesday in Austin, Texas.
There will not be a 8th Tour de France!
The allegations of doping in his former US Postal Service team that surfaced in 2010 and they will not just go away!
Did you know sit ups, crunches and back extensions do more harm to the lower back than most people realize. Now jump on your bike and you will realize more what a bad fit can cause an ouch!
Enlightening information protects your spine.
A couple of reasons to avoid these exercises:
1) "The sit-up imposes approximately 3300 N or about 730 pounds of compression on the spine." This means that every time you do a sit-up, knees bent with feet locked under something, sitting up from the ground to vertical, that amount of pressure is crushing your intervertebral discs. "The National Institute of Occupational Safety and Health has set the action limit for low back compression at 3300 N. Repetitive loading about this level is linked with higher injury rates in workers, yet this is imposed on the spine with each repetition of the sit-up!"
2) Back extensions are no better. On the roman chair (this is the piece of equipment that is set at 45 degrees and you can lock your feet and rest your thighs on it so that you can drop and lift your upper body, working the back) performing one back extension, imposes over 4000 N or about 890lbs of compression on the spine These types of exercises impose up to 6000 N or over 1300lbs of spinal load and compression, then add road noise. These exercises are referred to as the "superman". Please avoid these exercises at all bike fitting costs! The deadlift both work the back and spine in the biomechanically correct fashion. There is no isolation of the muscles and the body works as one functional unit.
How does the core function on a bike?
3) The most important aspect of abdominal muscle performance on a bike is obtaining the control that is necessary to A) Appropriately stabilize the spine, B) Maintain optimal alignment and movement relationships between the pelvis and spine to the saddle and C) Prevent excessive stress and motions of the pelvis during movements of the extremities i.e. too low of a saddle.
4) Hopefully Point C above enlightens you? You can see that what we are trying to do is train the core to stabilize the pelvis, and to efficiently transfer force to the arms and legs.
What does this all mean?
5) In cycling, there is obvious risk taken by working out, but if we can make good choices we can do a better job at avoiding injury.
6) In sports it is necessary to have abdominal strength in flexion. avoid too much spinal loading while still working hard. Cycling exercise can be tough and its best to work the abs while minimizing the spinal loading and reps performed.
Avoid any type of back extension where possible and try to work the core as it was meant to function. Lot's of front support, side support, and anti-extension exercises will make a difference.

My fees have increased for 2011.
No Complaints! For $300.00, or less, I can guarantee a minimum of 20+ watts without altering HR.
How? The WN fit is CAD based. It provides me the blueprint for your success. When correctly positioned, more effective muscle recruitment is possible, and pedaling technique is amenable.
The result is increased watts, without increased effort.
Every person that I have fit since training with Tom Coleman (Wobble-Naught “WN”) has achieved between 20-100 watt gains.
Penn Cycle & Chris Baiser are a real force. Chris is a real warrior!
ISM is really strong in straight line events, tri and gaining in tt.
New for 2011 and all about straight line performance!
Their report: From the start gate to the finish line, you will slice through the competition. ISM’s winning design allows for increased hip rotation, thus decreasing a rider’s aerodynamic drag and opens the diaphragm for easier breathing. Riders report an increase in wattage due to the more aggressive positioning. Sloped front arms provide extra relief to the superficial perineal space. NO NUMBNESS – NO PAIN. Uses light weight foam and gel pads with titanium alloy rails. 245mm long and 130mm wide.
Available in Black or White
MSRP $224.95
We have been telling the industry for years that hip rotation is key for performance.
That is why we find the correct tilt of saddle, not eye it.
But a 800 lb. ape can't communicate.
They claim upright is the way to go?
