Pearl Izumi Elite RD II Road Shoe Review



Pearl Izumi Elite RD II Road Shoes vs. Louis Garneu Ergo Air Pro Road Shoes:
Compared to the first road shoe I bought, the Pearl Izumi Elite RD II Road Shoes were excellent.  Prior to the PI's, I purchased the Louis Garneu Ergo Air Pro Road Shoe, a "Performance Bike Exclusive" shoe.  The fit and ventilation was excellent, but the major design flaw involved the buckle. The spring housed inside the buckle snapped the release tab.  Although Performance Bike offered to repair the buckle for free, I decided to return this shoe because I knew the material used in the buckle was too weak and it would eventually lead me to replace the buckle again and again.  Out of all the barriers that could get between me and my training, a defected.shoe should not be one of them.

The good:
After approximately 3,000 miles on these shoes with a few scrapes and impacts from criteriums/ fails, these shoes still looked great and have been extremely reliable from the start.  The buckle seemed to be composed of a more durable material and was designed more intelligently compared to the LG Ergo Air's. In order to lock/ unlock the buckle, it only requires only a little bit of force to release the strap.  I like this because it never feels like the buckle wants to break.  With regards to comfort and weight, the leather upper fit better and it also felt noticeably lighter than the LG Ergo Air, although I could not tell a big difference once they were on my feet.  In terms of performance, the carbon fiber was stiffer during high power efforts and hard accelerations, but the difference was small- I only noticed the difference because I consciously tried to feel for it.

The not so good:
In terms of ventilation, I have to admit that the LG Ergo Air's were better.  The LG Ergo Air had noticeably more ventilation than the PI Elite RD II- though I wouldn't sacrifice the PI Elite RD II's better fit just to have a little bit more ventilation.

About sizing for these shoes: 
For an idea of what size to buy, I wear 9.5's for most shoes and occasionally have to get 10's, but the 44's (Pearl Izumi) fit perfectly!

Pros:
  • Lightweight - carbon fiber
  • Ratchet Attachment
  • Not ugly
Cons:
  • No replaceable heel or toe pads
  • Could be a little more breathable..

Kinesiological Approach To Bike Fit: Cleat Position

CLEAT POSITION:  There are four types of adjustments which can be made to a cleat.
Fore/ Aft:  FORE:  Positioning the cleat forward allows the ankle to move more freely, allowing for a smoother pedal stroke.  The trade-off is that this requires more ankle stability, calf strength and puts the rider at risk of developing quad dominance.AFT:  This position limits ankle motion.  This provides added stability to the ankle, allowing the calves to rest, but makes the rider prone to bouncy pedal strokes.  When switching from a forward cleat position to a rearward position, a lower saddle position is needed to compensate for decreased plantarflexion.Lateral/ Medial:  The goal is to spread weight evenly across the foot side-to-side.LATERAL:  Shifts weight towards the outside of the foot (small toe side).MEDIAL:  Shifts more weight onto the medial side of the foot (big toe side).  Limits the maximum amount of external rotation available before the heel strikes the crank arm.Rotation:EXTERNAL:  S…

How To Hold an Aero Position

There are climbs and then there are winds.  For many cyclists, riding into a strong wind can be more difficult than climbing, mostly because cyclists are required to reach a low aerodynamic position which can be uncomfortable, difficult or painful to hold.  Cyclists must demonstrate adequatehamstringandlower backflexibility to hold an aero position comfortably.  The flexibility needed to ride well in the wind can take time to develop, but with enough dedication and experience, anyone can become proficient at holding an aero position safely.  Here are some steps you can take to make holding an aero posture as comfortable as being on the hoods:

#1 LEARN YOUR LIMITS.
The worst thing a rider could do is force a low aero position and hope for the best.  With low back pain being one of the most frequent complaints among pros and recreational cyclist alike, the chances of long term pain- or injury-free riding are slim.  Develop the flexibility first, then shoot for the next lowest position yo…

Eagle Creek Park Cycling Grand Prix v2.0 - FIRST PLACE & FIRST PODIUM FINISH!

I can't even begin to describe how awesome it felt to have two dreams come true at once!  I always wondered what it would be like to be on the podium, but I never thought I had a chance at first place!

THE COURSE Below is a map of the course highlighted in blue.  It ran counterclockwise.  There were a few corners that stuck out to me.
Bottom right (corner #1):  This wasn't a very sharp corner, but the trees and brush made it difficult to see around it, so the group had a tendency to slow down and merge into a single line here.
Top right (corner #2):  This corner was very sharp, so oftentimes the group would merge into one or two pacelines, especially at higher speeds.
Top left (corner #3):  The inside half of this corner was covered by loose asphalt, so it wasn't an ideal or safe place to pass.  Pretty much everyone had to take a very awkward, wide line.  We could only fit about three abreast in this corner.
Bottom left (corner #4):  This was a very fast corner that led straigh…
