Pros and cons of wheel rim designs.

Hi all, I am considering building up some new wheels for my road bike and am looking at rim choices. My current rims are DT Swiss 450s, chosen largely on budget (cheap!) but also on weight (450g). The 450 does not look the most aerodynamic of rims so I was looking at deeper sectioned rims and noticed that they seem to be considerably heavier (typically around 580g). I realise this weight difference is not really going to be a major issue (probably less than a half full water bottle) but it got me wondering, is there any advantage to improved aerodynamics if it comes at the cost of weight? Are there benefits to deeper rims that I am overlooking (stiffness etc)? I assume carbon rims would be both light and aero but I was comparing like for like, in this case aluminium, and I want to keep things affordable.

Do you ride for extended periods at speeds over 25 or 30km/h? Prioritise aero.

Do you do a lot of stop-start riding (eg traffic lights), a lot of sprints, or a lot of climbing? Prioritise low weight.

Do you commute, brake heavily, or else ride with a total lack of mechanical sympathy, crashing through potholes or bouncing up kerbs? Prioritise robustness, which probably means higher weight.

Do you race? If not, prioritise aesthetics, as the performance differences are irrelevant (and you can always claim you're trying for a greater training effect).

Lol, bang on.

Thanks for the advice, I shall bear it in mind.

I quite like a 32 spoke, 3 cross pattern, I have a23's on hope hubs. Archetypes are popular in this bracket.

If well built they will be strong, stiff and on the heavy side.

How heavy are you?

They're vey nice, I weigh about 70kg I think.

Does anyone use asymmetric rims? Bontrager put forward a plausible argument for them.
Looking at the options though, I'll almost certainly end up buying another pair of 450s. DP18s are very affordable now I notice but aesthetically nothing like the old ones and still a bit heavy for my puny legs!

So I asked about aero advantage in the aero thread...

seems to be that if you will save about 15s over 10 miles at 20mph with top of the range aero wheels vs 32 spoke none aero wheels. Not worth the cost for me.

Get some kinlin rims. Cheap and light

go to a wheel builder...

For this, I am going to assume a rider weight between 50kg and 95kg. Beyond 95kg you may want to look at alternatives. Generally riders below 75kg I recommend 20:24 lacing. Above 75kg I recommend 24:28 lacing. Sets are in ascending price order.

NovaTec A171/F172, Kinlin XR-270 rims, Sapim Race spokes brass nipples(24:28)
£220. Approximately 1660g.

I can't go to a wheel builder, I love building wheels! I agree with you dst and jsabine, aero's not worth the money for a rider like me. Kinlin look nice but so far nothing's beating 450g for £35.

Do you want tubeless?

No, I've got tubs on my fixie, but not for me on a road bike.

Tubeless is not tubular

Sorry, they were always called "tubs" in our house; I have tubeless on my fixie.

have a look at the DT swiss 460. wider, can go tubeless, £35 a rim, guessing 10g heaver per rim.

the max tyre with on the 450 is 25. That might limit you.

Unless tubeless is something else...

clincher with no tube in it. the newest bestest thing

We are talking old style glue them on aren't we?

I'm not keeping up here

no.....diffrent

I will look in to it... technology moves too fast!

No, tubeless is not tubular

I can keep repeating myself.

not done it myself but will when my current tyres die.
