It takes 1/3 as many watts to go 20 as 30, so I would give your bars 2 watts if you ride at 20.

Chains.

Some guy in our group ride had a very fancy looking time-trial bike. Every once in a while he would sprint past the group, and it was very noisy. The noise made me think it was inefficient either mechanically or aerodynamically.

The fact that they make no claims about the aero of my frame probably means that it was ok, but not in a way that beat anything else. Run that calculator I linked to: http://www.cyclingpowerlab.com/ComponentAerodynamics.aspx Cervelo S3 is 2 watts at 28 kph. So aero frame is waste of money. You reall...

I would like to add up all of the watt savings I implemented since Aug. Watts are speed-dependent, so I will say for 30 kph. 1.

Shimano has to make them also work for the 260 lb guy who races down hill and hits a pothole.

I wonder why Shimano does not just do that?

Most light bikes seem to use Red. That is a great deal for what is probably the best choice.

Dura Ace skewers are heavy but I am not planning to change them. When I get my tires I will recheck the weight. Should be 16 lbs.

Since the C24 wheel is slightly larger than typical, they should have called that a 25mm tire. The bike looks very good. There is that test that shows it as faster. I go to great lengths to only buy things Amazon Prime. I came very close to not getting latex tubes since Amazon didn't have any in 25-...

The day that I learned that I had to carry a spare tubular tire with my tubular wheels was when I realized that the weight savings of tubular wheels was not real unless you have a team-car following you.

Can't I just carry a patch kit?

I wish these had lower Crr as I love how they look (true slick): But about 6 watts worse than a GP4000SII per pair. Just because the Pro4 Service Course and Comp are not at the very top of the Crr chart does not in any way assume they’re not good tires. As I mentioned previously, I think tires like ...

When I was shopping for tubes, the title would say 25-32mm but the description would say 18-23mm. So I could not take the risk of buying from them.

Then there were the ones that said 700x25 inch.

Oh. Thanks. I wish my wheels were wider, but that is the C50 or C75.

In any case, I ordered 25-622 tires, which is how I think sizes should be listed, and tubes marked as 25-28.

http://www.bicyclerollingresistance.com/specials/conti-gp4000s-ii-23-25-28 The 23 is 25mm wide. The 25 is 27mm wide. And that is on 17mm wide wheels. My wheels are 20.8. http://www.bicyclerollingresistance.com/road-bike-reviews/vittoria-open-corsa-cx-iii-latex-tube-2014 Open Corsa CX-III 25mm is 28m...

I ordered Conti. They are $48 each with 2-day Amazon Prime free shipping. One thing that I liked was that people say that the 23mm measure 25mm on a 17mm wheel. I have a 20.8mm wheel. I ordered the 25mm and I bet they measure 28mm wide when mounted, but yet less than 28mm tall - so they should fit. ...

Some people complain about the GP4000 ride quality and/or sidewall blowouts. Other people give them stellar reviews. People in my club think the Michelin Pro4 is the best all-around tire. Taking the tires off - sealant was a bit messy. Not horrible as it didn't spill. But still, I think you may be r...

How do we know these are better tires than the GP4000S?

They had a buy one get one free promotion on the tires last April:

http://www.solonbicycle.com/about/world ... -pg157.htm

I bet their 26 would fit my bike.

They are $100 each on their website. I think you said $55 each.

What should I do - sell both and get 25mm/25mm to have matching size, or sell one of them and put 28mm on the front and 25mm on the back?

Sounds like you purposely put a larger one on front. Why did you do that and does your reasoning apply to me?

Where did you order the tires from?

I am getting some rub on the cross support beside the brake. I can't use these. I have to get 25s.

Anyone want to buy these from me from what I have into them?

Playing around with the European websites last night, it seems that Starbike is the cheapest if you get the 5% weightweenies discount. I compared Merlin, Ribble, Bike24, and Starbike. For the helmet? If you back-search eBay, they sometimes are about $155 shipped. Sometimes less. There are none now ...

My Pro One 28mm tires arrived today from Starbike. Ordered on 10/25. So seven days. Was able to get it on by hand but had to use some soapy water to stretch the last bit over the wheel without using a tire lever. It inflated with a compressor. So far I have no sealant in them and will see if they ho...
