Velothon Stockholm

Riding in Stockholm on closed roads probably makes the cost of riding Velothon worth it. Rode 160km incl 5km master without meeting a single moving vehicle and with good signs and people along the course helping us. The event was awesome if you ask me.

But when you gather the fastest non-racers that is doing their last ”race” of the season and want to press their record even more than it can be dangerous. Never seen so many crashes as today and it seemed like everyone in the 1st group was stressed and wanted to pass. I almost went down twice…

But except that it was quiet awesome. Riding in a really big group in up to 50km/h felt easy sometimes. When it felt slow it was around 42km/h. The hard thing is to sit in right position, cover gaps and to advance, that takes a lot of energy. So after we turned in Nynäshamn and came up to Sorunda it felt like my legs were empty and I would drop any minute. The group had become smaller so it was a bit better but not so far too fall as before.

I’m to bad to drop so I bite in harder and pushed as good as I could trying to ride easy and rest when ever possible to have powers for the fast parts.

After Västerhaninge I dropped the 1st group, people flew by but in some strange way I managed to dig deeper and got a wheel again and we got back up to the group. A bit later a was behind one who dropped and had to try chase up to the first group, enough people passed so I could hang on and get up again. My last drop 😉 In Västberga it was many tight corners and bad roads so the 1st group got split up a bit I think and we were a lot of chasers just behind and never got back up in the end.

Fastest time was 3h45min34sec over the 155km and I came in at 3h47min37sec so just about 2min later. Impressed with being able to hang on with 40,8km/h in average speed for so long. Never thought so before the start. 😀

Sram MY2013 vs Shimano 11-speed

First a document from Shimano leaked out showing the ny Dura-ace 9000 comes with 11-speed and will come in august. Then another document came out showing all the part numbers:

And some text that shows that there will be a new crankset with 4-bolt and that they will stay with 24mm axle. More is they got a new Direct Mount brake that mounts with one bolt one each side like some tt-bikes have. The new STIs will be even smaller and it will be 38% easier to gear up to the bigger chainring on the crank. Will be a electronic group with harness like Ultegra Di2. The mechanical group will be 1908g, 67g lighter than D-A7900. And the will come two new mechanical disc brakes.

For this 11-speed you can’t use 10-speed hubs (not so good like Campagnolo) So Shimano is coming with some new wheels too. 75, 50 and 35mm in carbon fibre for tubular. 50, 35 and 24mm in alu/carbon for clincher. And 24mm for tubeless. This wheels will work with 10-speed group sets and Sram with a spacer. Hub spacing will remain 130mm.

Then off to the competitor. Sram Red as you seen little of in the video earlier today.

Good design as always but maybe not so huge news as everyone hoped. Sram will stay will 10-speed. But will make it better, lighter and stiffer. To start with a bad thing with todays Red, the cassette doesn’t work for CX or in mud. New cassette is like an XX but better, and an 11-28 Redcassette will be the same weight as todays 11-23.

The shifters will have a little bigger knob and you’re able to change a gel padding under the hoods if you want the shifters to be more comfortable. The best good news about this new Red group is the front derailleur. The one we can buy and use at the moment is crap with its weak titanium cage. And Sram listened and made the new one much better with a hole new movement to make the shifting the best and to don’t have to use this small steps to stop the chain from scratching. To make this hole thing better they also worked on the crankset. 4 visual arms and one bolt on the back of the crank arm, like Campagnolo. This with a more hollow carbon feature makes the new crankset lighter and stiffer.

And then it continues. The new brakes are getting changed from this normal dual-pivot and use a cam technology like Ciamillo uses. This is the normal brakes for the Red group. But they are also working on hydraulic rim brake and hydraulic disc brakes. Mostly on the rim brakes that maybe will be released from the beginning. Interesting.

But 10-speed, no electronic and still seems to use Double-tap, should we upgrade? The good thing with Sram is the weight. The new group set (probably with mechanical brakes) is said to be 250-280g lighter than todays Red. Like 1700g for the group. Impossible for Shimano and Campagnolo to beat?

And we will see if you have to come up with something new like Campagnolo EPS, or Shimano 11-speed to be good or if it’s enough with tweaking the things you have, with quick good shiftings, sleek look and an weight a couple of hundred grams lighter than the others to be the winning group set. Keep on fighting! What do you readers think about the three new group set or what do you wish from them?

Campagnolo 2011

Såg en intressant bild på ett nytt vevparti ifrån Campagnolo. Istället för deras vanliga Ultra Torque där axeln är delad i mitten så är de som vanliga vevpartier och kollas numera Power Torque. Om det bara blir för de billigare vevpartierna eller dyrare vet jag inte men ser inte så dyrt ut.

Läste även om att fördelen med Campagnolos vanliga Ultra Torque är att det går att få tajtare i mitten och det blir mer plats för anklarna. Som det även blir med ett BB30vevparti, i alla fall mitt Sram Force. Var även en bild på Campagnolos nya cykelcrossvevpartier men vet inte exakt vad som skiljer sig jämför med de vanliga.

till salu: KCNC RD1 vevparti

En kompis som funderade på att köpa mitt vevparti tvekar så nu lägger jag ut det öppet så vem som helst kan köpa.

KCNC RD1 med KCNCs variant av utanpåliggande lager K-Type. Vevpartiet är kanske inte styvast som Dura-Ace men riktigt styvt för sin vikt och fick bra i ett stort test som jag har för mig Fairwheelbikes gjorde. Jämför du med Shimano 105 eller något sådant så känner du troligen ingen skillnad

Säljer med orginal 39/53 klingor i bra skick. 50t storklinga på bilden.

170mm vevarmar

K-Typevevlager för 68mm BSA

Vikt: 721g med rätt klinga har jag för mig, 712g som på bilden.

Kan skickas och säljs med orginalkartong och bruksanvisning

Pris: 1400kr eller högstbjudande
