6/4 seamles Ti frames from mom and pop - Guru?(9 posts)

6/4 seamles Ti frames from mom and pop - Guru?Chainstay

How is this done that a small manufacturer can source specialized tubing, design, test and build with the most advanced technology? They not only have Ti bikes but they have full carbon and the latest fad, Ti lugged carbon frames. Are they just a marketing arm with mostly brand labels? Where did these guys come from all of a sudden with customization, colours etc? Are they owned by someone else?

They have a pretty good rep for high end AL bikes. Haven't heard much about their other offerings, but they tend to be pretty pricey.

Simon Whitfield rides a custom Guru, won the Sydney Olympics tri using that bike. They're a Canadian company, been going for a while, do all their own building AFAIK so you can even get the Ti bikes custom-built. I've seen them at races, very nice bikes indeed.

I know Guru and I'm not knocking them. I'm just trying to understand how they can branch out from AL into now making the latest in Ti and carbon fibre technology. I figure they are sourcing the product designs from somewhere.

They buy the tubes from Reynolds as a set just like everyone else.
Does Reynolds design frames for their recommended tubesets?Chainstay

I was under the impression that the large Ti buyers had leverage and that something like 6/4 seamless was hard to get and took some develoment time to sort out the frame design. I guess you are saying is that Reynolds does a lot to help the manufacturers use their product by essentially pre-designing the frames with standard tubesets. I actually didn't know, until now, that Reynolds was a in any material other than steel.

While 6/4 is a great alloy, there is no inherent benefit to seamless tubing, and it almost certainly is not butted. Further it is not tapered, swaged, or shaped. I'd go for a properly executed tube made from rolled/welded sheet any day over a straight gauge, seamless tube.

According to the Reynolds website the 6/4 Ti is butted.

They also refer to the inherent advantage of seamless here

over 6 years and they have never split at the seam. That shouldn't be a concern for anyone. Litespeed told me that they have never seen a 6/4 tube break at the seam. If they have failures they are at the joints. Seamless 6/4 seems like a fine idea and if it works, great, but I would look at who is making the frame. No one does 6/4 ti better than Litespeed.
