CrankShaft Posted January 29, 2018 Posted January 29, 2018 My zipp 404 FCs are about 2kmh faster average speed than my Shamals on any given day for the same fitness and route. My Zondas are 1kmh faster than the shamals though. They are 17c vs 15c. All sets have 25c Conti GP4000s Zondas are 5k ... Shamals 13k Zipps 28k No money - buy the Zondas with credit card .Got cash to bling - buy the ZippsGot just enough - get Shamal 17c

Bitumenous Posted January 30, 2018 Posted January 30, 2018 Morning y’all, so which rims are actually worth getting? Where do I go to shop for rims? And NO, deep pockets I dnt have (just bought a bike) I am currently running on Campy Scirocco 35mm
Bitumenous Posted January 30, 2018 Posted January 30, 2018 Ok I posted before I read. Sounds lome the previous message is a good indication ????

I'm also a Campy wheel fan, those wheels are awesome
Paul Ruinaard Posted January 30, 2018 Posted January 30, 2018 Carbon rims are great for eating up some of that road buzz. My average speeds are faster on carbon than aluminium. So are you saying carbon rims are like a carbon frame and can actually reduce road buzz if made correctly. I was always under the impression that carbon rims were more rigid than ally, so were harsher than ally rims, or am i misinformed?
Martin PJ Posted January 30, 2018 Posted January 30, 2018 I rode with Chinese carbons for three years training. They were good value for money. The front wheel melted in a race coming down a mountain pass. So don't use them on very hilly races. I believe this is possible with most carbon wheels that are clinchers. I had Campag Boras that were 10 years old, they were very fast on flats. Gave them to my son, now he races with them. Before that I had old Zipps 404's they climbed very well because the back wheel is so stiff. Also pretty fast on the flats. Maybe as fast as the Boras'. These were both tubbies, which are better imo for races, they can ride through potholes and the clinchers can't really. The tubbies are less likely to delaminate from braking heat because the braking surface is not being pushed apart by the tire, the tire at 10 bar actually strengthens the wheel, punctures are a pain through, as it is not so easy to repair the tubbies.

Thomo Posted January 30, 2018 Posted January 30, 2018 If the Zondas are quicker than the Shamals, why even consider the Shamals?I think he said get the 17 Shamals, as opposed the the 15 which he had.
'Dale Posted January 31, 2018 Posted January 31, 2018 They just look so damn goodEnough reason to get a pair
Mountain_Goat Posted January 31, 2018 Posted January 31, 2018 Quick question, everyone says that carbon wheels can melt/delaminate when doing too much decending or breaking on steep decents but I've noticed all those videos and articles ect are from Europe. Here in Cape Town however, our climbs are nothing compared to the climbs in the other parts of the world so my question is should one be concerned about the possibilty of melting/delamination due to braking on what we would consider steep/long decents here by us?
mecheng89 Posted January 31, 2018 Posted January 31, 2018 High speeds - Carbon 50mmVery high speeds - Carbon 60-80mmClimbing - alu OR carbon 35mm So, it depends on your location where you ride/train, and the types of races you partake in. My personal experience - they accelerate better, but the weight advantage isn't as much as one hopes. Braking the wet is ***. Noise from the brake pads suck. Proper pads are expensive. But they sound wonderful (rolling).

I was always under the impression that carbon rims were more rigid than ally, so were harsher than ally rims, or am i misinformed?Carbon is designed to be stiffer, which gives the impression that power transfer in more efficient (less loss through flex). Aluminium is a more compliant material, but there is the slightest weight penalty. Bike manufacturers are hard at work making carbon frames more comfortable. Aero bikes for example have a generally stiffer chassis compared to the comfort ranges, so NOT recommended for races like the Fast one .

This is for clinchers, I believe tubbies would perform better as there is no outward pressure if the rim is slightly plasticised. My rim melted coming down De Beers pass near Ladysmith, it was pretty steep, the rim melted about one third the way down the pass. I was braking a lot.

Agree with what Martin has said.From the research that I've done the problem is with carbon clincher deep sections. Tubbies don't seem to have the braking problem or it's a lot less significant. In SA they still melt. Know somebody who used a Chinese carbon set for about 3 or 4 years and then the brake pad went through as it had worn out.
