Im using zip p 303 for all purpose ride. I was advise to get a climbing wheels like 101, frlcrum zero LE, or maybe notubes alpha 340. 303 is 45mm. Will lower profile wheel like 24mm helps and can climb better ? Please advise.
All things being equal (ie weight), the the deeper section aero wheel will be faster in ALL conditions. Including steep climbs. The speed advantage will be greater the flatter things get.
Unfortunately, assuming you are talking about the same manufacturer/rim material/rim design, the deeper section aero wheel will weigh more than the shallower section "less aero" wheel. So you have the classic trade-off between aero or light weight.
A good example would be the Enve 6.7s vs the Enve 3.4s vs the Enve 1.25s.
At the speeds the PROS ascend "moderate" climbs (5-6%), the deep 6.7 wheels will be fastest. As the grade increases, speeds decrease, the aero advantage decreases, and weight factors in more. So at some point (we're just estimating %'s here), the PROS will find that the 3.4s will be faster than the 6.7s when the grade is, say, 7-9% and that something superlight but less aero (the 1.25s) are fastest when the grade is 10% or above.
This does not factor in "feel" or the ability to vary tempo on those grade climbs. A guy like Wiggins who climbs like Indurain (steady) will likely stick to these recommendations, while a guy like Contador who climbs like Pantani (huge kicks, change of pace) might favor a lighter, less aero wheel.
The trick here is that this is what works for the PROS, at PRO speeds. If you climb a 4% grade at 20mph like these guys do, then don't worry so much about the weight, and ride deep section aero wheels. You'll be faster. But if you're the average weekend warrior with an FTP at 3.5 W/Kg, then you can reduce all those percentages, because you will be climbing at a slower speed than the pros and thus the aero/weight trade-off shifts in favor of weight. So maybe you ditch the 6.7s for the 3.4s when the grade hits 4%, and find that the 1.25s are faster than the 3.4s when you're at 6-7%. That's the idea anyways - the slower you climb, the more you want to favor light weight over aero.
Of course, most rides involve flat sections and downhills - on all of those sections, your deep section aero wheels will be faster.
Finally, most climbing also involves descending, and descending often involves dealing with crosswinds, and sometimes gusty crosswinds. Some riders will handle these conditions without a complaint, others will find that high-speed descending on deep section aero wheels is a near-death experience... and if that causes you to grab your brakes to stay alive, you will lose time. So make sure you can handle your wheels of choice in a strong wind - if you can't, there's a good chance we will see them here in the Classifieds after a spooky session in the mountains.
