Wondering on bike set-up, if there is a balance between having the arm pads in the best place for aero riding vs having room for a more forward out of the saddle position for climbs.
Second question is about goggles. I’m using basico Speedos and am left with goggle rings for several hours after a swim, really adds years to my already actual oldness (bet spellchecker won’t find THAT one). Is there a goggle/brand that is kind and gentle to the eye sockets? Thx, Dave W.
On your first question:
Some riders with short-ish torsos and long-ish femurs may find themselves in a position where their knees hit their elbow pads when they climb out of the saddle on their triathlon bikes.
The best and most practical answer I’ve heard to this dilemma was Dan Empfield’s suggestion to me at a F.I.S.T. clinic to adapt an additional climbing technique specifically for use with aerobars.
If you slide slightly (more) forward, gear *way *down and use a slightly higher cadence you may find better poower output with a slightly lower heart rate than you may experience standing and climbing out of the saddle. This posture facilitates (relatively) high speed climbing even on long gradients at something near optimal power outputs while avoiding busting a knee against your aerobar pad.
Sometimes it is just a matter of the right (or different) technique at the right time.
Question two: try Barracudas.
Go to your swim/sporting goods store and try on every pair of goggles they have there. Buy the ones that stick to your face the best without using the strap.
Go to another store and do the same thing untill you have tried every single goggle available. By no means get that silly seal mask

Another thumbs up for the Barracudas. Not the cheapest but certainly one of the most comfortable.

Second question is about goggles
Goggles are like saddles. Try them all. One persons wonder product is anothers torture device. That said Swedes work well for me.
reply about goggles…I haven’t tried this, but swim instructor says it works; loosen the strap and apply chapstick to the silicone that goes around your eyes. She said that it helps them seal and you don’t need extra force from a tight strap.
Dave, regarding the climbing issue…I’m going offer two suggestions and the first one might be overlapping Tom’s note. On a gradual climb, one option is to remain in the arrow position and slide to the nose of the saddle - put 80% of your body weight in arm pads and pedals and only 20% on the tip of the saddle (on your 'taint) and - this part’s critical - keep the cadence HIGH 90+ rpm.
In a situation where the climb is short and steep and deserves to be “attacked” out of the saddle…then climb standing, but leave your hips back over your seat. As the bike rocks a bit side to side you should feel the tip of the saddle touching each cheek or there abouts - this should keep the knees away from the arm pads (and you may find you climb with more power too).
All the best, Ian
