BTW here's a link to some personal reviews (and you can look at other reviews at this site): http://tinyurl.com/6a7yb
Just have been browsing some older issues of the Tour magazines in search for the promised rain tire test (asdf where is it) and ran across a tire shootout between the Conti Attack/Force and the Schwalbe Stelvio Evo Front/Rear, where they gave explicit numbers for the tires' adhesion in wet conditions.
Conti Attack/Force // Schwalbe Stelvio Evo Front/Rear
real width: 20.8/22.1 // 21.4/22.5
weight: 191/208 // 243/231
wall thickness: 2.6, 0.5/2.8, 0.5 // 3.2, 0.6/3.3, 0.6
rolling resistance coefficient: 0.0068/0.0064 // 0.0076/0.0064
rolling efficiency: 43W // 45.3W
rolling resistance: ***/**** // ***/****
stabbing time: 79/180 // 140/145
puncture safety: ***/***** // ****/****
adhesion factor in wet (wet adhesion, sliding friciton): 0.54, 0.43/0.58, 0.43 // 0.56, 0.5/0.57, 0.49
difference (adhesion/friction): 21%/26% // 10%/14%
Wet adhesion: ***/*** // *****/*****
wear: medium/medium // high/very high
Thanks for the comparison between the 2 rain tires. However, its difficult to understand the numebrw and what they mean. Obvoiusly, width, weight, wall thickness, and wear are easy to figure out. I am a bit confused on the other factors and if higher or lower numbers are an advantage or not. can you translate? Thanks
The wattage number e.g. is measured at 30km/h with 7.5 bar pressure for 80kg total weight (rider+bike) and 56% of the weight on the rear wheel
Here the Conti saves 2.3Watts over the Schwalbe.
Adhesion based numbers: the higher the better.
And even more good if the numbers are close together (a low "%"-number for difference).
Those stars (*) help to clarify the results.
***** very good
Seems like you have used the veloflex Pave's in the rain. Those schwalbe rain tires are currently backordered about 5 weeks in the 23cm size. I would try them, but i want to set up this bike right away. I would love to know if the pave's are really good in wet conditions. they are the best tire i have ever ridden in dry conditions and would love to have the confidence to ride them in the rain. Appreciate everyones opinion, but i am no longer a big fan of any conti tire, so i will not go back to the ATTACK/FORCE combo. If the scwalbe tires are that good in the rain and worth waiting for, i can deal with what i have for a month or so. any more input would be greatly appreciated on the Pave's in the rain.
If you were to ride a crit, I'd perhaps go for the Schwalbe, because of the so-said best grip (haven't tried them myself). For everything else I'd be more than pleased with the Veloflex. Although their puncture safety might be argued, though I myself cannot confirm those rumors /about puncture safety) - Conti had been _much_ worse to me.
