don't see how they would help you. they would only bring your ankles further out but consider the 4 mm in relation to a seat height of let's say 750 mm
i find them helpful because of too little foot/ankle clearance (wide and flat feet)

i only have to look down to see that i now have proper clearance and do not run the risk of touching the crank arms especially when wearing booties
if 4 mm is too much, one can still move cleats
the only drawback for those racing criteriums (and all others that like to pedal through corners..) is the smaller ground clearance when cornering
Don't the extenders only come in one (?) length of about 20mm?rpenmanparker wrote:If you don't want to commit to the longer pedal spindles, you can get extender bushings to set the pedals wider. Then if you like that, you can get the wider pedals, or just stick with the bushings.
And the ones i've cursed and sworn at are only suited for use with pedals including spanner flats.

How do you determine if a rider needs a longer axle and can it be measured before purchasing? Is there a certain pelvis width that dictates a longer axle?
When you have a normal body build and move your feet just normal straight on the pedals, go standard.
Do you have larger feet, strange angles in legs/feet and touch the crancks frequently is there? Go for a longer spindle.
Also some shoes require bit more room than others. (Can remember people complaint about older types of Fizik shoes)
If you have a bike or used in the past you can look up spindle size to get an idea.
Knee should track over 2nd metatarsal.
Some riders need to be narrow, some need to be wider. Lower Q is not always better.
Have someone who knows how you pedal watch you ride.
You can play with width to some degree by moving cleats and adding 1mm pedal spacers. Most pedals can take 3mm of spacers.
If you get as wide as you can go with the 3mm of spacers and cleats full wide- you may be a good candidate for the +4mm pedals.
