http://www.sevencycles.com/bikes/duo65.html I think it is a cool idea, but coming from 7 i think it might be a bit light
Its tie because it is all costom geo and that would be to hard for them to do in an AL bike, as well its lighter than steelRik said:What makes titanium special for a dual suspension bike?
It's as bad as cromo duallies that have "real steel feel"
Ti also does a full carbon bike and steel as well as a cromo carbon and ti carbon mix. So ti is not necisaraly "what they do" at seven, although the bulk of what they do if for the reasons i stated aboveCreeP said:it's because titanium is what they do at seven.
Remember when that suspension design was a URT? I don't.Sandwich said:Remember when URTs were cool? I don't.
Especially ones that do things that shocks aren't really meant to do, such as taking twisting and side loading.Sandwich said:Proprietary shocks are dumb anyways.
dont worry, it's not a shock, but rather a STRUT. Cars have 'em, planes have em.....uhh your FORK is basically one. Struts are designed to take such loading, thats why the arent coil-overs.Rik said:Especially ones that do things that shocks aren't really meant to do, such as taking twisting and side loading.
Yeah, because welding Ti is so much easier than welding Al...TheMontashu said:Its tie because it is all costom geo and that would be to hard for them to do in an AL bike, as well its lighter than steel
no no no....it's because Al gets cranky when you keep changing it's geometry; Ti is more mature and embraces diversity....MikeD said:Yeah, because welding Ti is so much easier than welding Al...
True, I thought about that but I'm sure the rear end would experience alot more hell than a fork ever would, and secondly a strut in the applications mentioned can take such loads, but given the design constraints of a bicycle (weight + cost being major factors), would anything have been compromised in the design that could lead to durability/longevity issues?zedro said:dont worry, it's not a shock, but rather a STRUT.

well just look at the lefty, and just think of all of the front line work the fork has to do. In this case the strut is handeling the longitudinal forces almost exclusively; the lower linkage handles most of the lateral. But its all pretty moot since the bike is only built for a certain level of abuse, but a properly designed strut would work fine in a DH application evenRik said:True, I thought about that but I'm sure the rear end would experience alot more hell than a fork ever would, and secondly a strut in the applications mentioned can take such loads, but given the design constraints of a bicycle (weight + cost being major factors), would anything have been compromised in the design that could lead to durability/longevity issues?
Thirdly, as mentioned... regardless of the above (I'm probably wrong anyway) proprietry parts =
Um yeah and you know like a DW link is just like a single pivot with more pivots...Sandwich said:ok, whatever, it's a urt with another pivot. Or an I drive with no dogbone. It's a half urt. A HURT.
...aannd the BB is still not on the swingarm. Ain't nothing you or anyone else can say that's gonna change itDHS said:having your bb on the swing arm, F-that
how will i reach you inside that box?thaflyinfatman said:Call me next time you service or revalve your swingarm.
I think that that's 'cause of the flexiness of ti. I don't think that many susmension designs function too well if the parts are flexing, so it's not a great choice for the rear end of a suspension bike that has any pivots.Jm_ said:The sad part is that it's only half titanium. Full titanium suspension bikes are extremely rare.
still apart of it and moves. i don't want my feet moving with the swing arm, if i wanted a hard tail i'd buy one.binary visions said:...aannd the BB is still not on the swingarm. Ain't nothing you or anyone else can say that's gonna change it
Ever tried to get parts or service in Australia?zedro said:how will i reach you inside that box?
I have riddin around the klien on a trail as well as a mavrick. I have bounced around in a parking lot on a duo and a duo-lux (and 5 or 6 othern7s) for that matter.klunky said:Those bikes actually ride really nice (well the klein version I rode did). I think the rear axle path is supposed to be similar to the front.
Its designed by Paul Turner.
In reviews it has been stated that it is the best climbing bike out there.
