New Wheels

I’ve been bitten by the upgrade bug…..Oh No!!

Just put a set of Neuvation R28’s on my Roubaix. Not sure exactly how much weight loss was attained, but I’m guessing about 1 pound. Of course I have to justify the purchase, so I headed for a hill I climb frequently. Its about 1.5 miles long and the grade averages about 7% with the steepest bits around 10%.

Nothing scientific, just watching the Flight Deck, my slowest speed was 1 mph faster than my slowest speed with the old wheels. The lowest gear I used was 1 cog higher than I used previously. In general, I just felt faster.

I read an article recently that tried to mathematically debunk the rotational mass argument. It made sense at the time, now I’m not so sure.

Now the question…is it the wheels or “placebo effect”? What’s been your experience?

I guess my purpose is served, regardless of how; I’m a little faster on the hills.

Bit of both.Stock wheels that come with a bike are generally machine built and they are not perfect in many ways. Different spoke tension- possibly out of true or Oval. On top of that the cheaper wheels have cheaper hubs and the bearings will not be perfectly set up. By going to a better quality wheel, although they may still be machine built, they are made of better components and are checked after build to ensure they are good. So the wheel is better so they will do their job more efficiently.

I recently got a pair of hand built Ultegra wheels. The ultegra wheel that was tweaked by a builder before I got my hand on them. They have made a difference over the hand built "Training" wheels that I got earlier in the year. I checked them out up against the trainer's and they are faster. No Placebo effect for me as I just did a ride on Sunday- that I did on the saturday- in the same weather conditions and all that had changed on the bike was the wheel. Even used the same model of tyre at the same pressure. So in my opinion- The better the wheel- the faster the rider. Or was it that I had changed the tyres to one that I know I like, from one that I was a bit wary of?

And on the rotational mass- Acceleration with a lighter wheel is far better. Once up to speed- then I doubt that they have any advantage- but All that braking and slowing for corners takes momentum out of your steady pace. Lighter wheels will help you get back up to speed quicker and on hills- Lighter wheels and a lighter bike and 150lbs body mass do work.

I guess you didn't have any problems putting 28s on your bike then, by the sound of your post. Now you got me thinking about going the same way. Not right now, but in the near future. How much clearance did you have?

George, R28 is the model number of the wheel not the tire size. I'm running 23's on mine, so I can't be much help on the "will 28's fit thread".
