Why is there no topic about the new M5 cranks yet?

Seen yesterday at bike motion.

Has anyone made pictures?

I really liked the BB, crankarms are very square, they are milled 7075 Aluminium, black anodised.

They put TA chainrings on, 110 mm.

238 grams must be a new record............

That's absurd -- 238g for a crankset? That's lighter than most brake sets. I'm a little incredulous.

I saw them at Bikemotion this afternoon. 238 g claimed, integrated design. Didnt look that special at first site, just (ano) black with ano red bearing cups, no logo's (yet). Probably hollow since I didnt see any machining at the back of the arms, like the Extralite's.

I've seen them today and talked to the producers. Looks great and they are really light, I had them in my hands. M5 also claims they're stiffer that Clavicula's.

They were only finished yesterday afternoon and arrived at the trade show at about 5pm. The guy from M5 asked to wait to post pictures till after the show (then he will have pics on his website). I couldn't take pics today, but will do so tomorrow; I might not come online untill Monday or Thursday night... sorry.

Let me get this right: 238g for two cranks and the BB too? That's the same weight as a Chorus BB alone :o

Can't wait for more news....

...look out for a THM Clavicula in the For Sale section!

Btw, :welcome: Daan! Nice topic you chose as your first, will lead to some pretty hefty discussions I think.

Saw them only very shortly and they looked not that light (so they have to be hollow). It was the first finished crankset so I think testing still has to be done (if they are in the stadium where 0g where early this year it could last a long time before these are ready to sell).

The guys from M5 told these cranks would be available begin January 2007. They will have a nice finish with the M5 logo on it.

"Weight is less than the Clavicula; price will be also", he said. So I asked "how much will it be?" and he estimted about 750 euro.


btw: it was nice meeting you, sharkman. And thanks for the goodies you brought me. I just mounted the Tune Skyline skewers: they look awesome.

Just received an email from Bram Moens, apparently, 238 is for the arms only, the axle and cups weigh another 120 g:

They should read the add carefully.......238 gram for the cranks in 175 mm with a 110 mm BCD , 120 gram for the axle, bearings and bearingholders, blades too choose....Will come later by M5 in a lightweight version as well offcourse.

The rear hub is 164 gram.

best regards, Bram Moens/M5

Still very light!!

looks very spartan. not quite as revolutionary in design as i was expecting - though if i am right, the cool stuff is hidden inside. the spider strikes me as both a bit agrarian, as well as elegantly simple and perfect for the tt crowd (in a 130)... i have asked bram and srm about doing a powermeter version, but haven't had any response from either of them. once we get a few in hand i can send one to srm and see if they would be interested.

can't wait to get my hands on them...

They look rather.............plain, I guess. All the goddies must be hidden. It'll interesting to see what comes out first, these or the boxers.
