Uber-Tall Cockpit Dilemma

[Mike S]

Now that I've been riding my ridiculously perfect-fitting 64cm Sam
Hillborne a bit, it's become clear to me that my 64cm Quickbeam w/
Dirtdrop stem & moustache bars gives me less extension than is ideal.
I impulsively bought the QB when it first debuted, and I should have
gotten a 66 or 68 over the 64. Also, using the Nitto lugged seatpost
as far back as possible, and it's still not enough reach.

In addition to not being enough reach, the Dirtdrop is at the minimum
insertion line and it's only about even with the saddle, and I'd like
it higher. The option I am most in favor of right now would be
replacing the DD with a 13cm tallux, in the belief that a technomic
would give me more horizontal extension than a DD, and the 3cm
additional quill length would make up for the loss of up-angle. I'm
also considering being slightly reckless and raising it above the min.
insertion mark if I can't get enough height in regulation.

The other option would be to get the stem extension Riv sells and
throw a technomic in there I guess, but the thought of the something
so kludgy on an otherwise excessively nice setup is a little
horrifying for my perfectionism to bear.

I'm just wondering if there are any of you tall dudes who've had
similar issues with getting bikes to fit, and if my hypothesis will
actually work in achieving more extension AND stem height. Thanks for
any input!

have you looked at the super tall periscopa? Ben's cycles has them in I believe but with only 80mm extension might not be what you are looking for.

I don't have any tactical help to give you besides encouragement to try whatever your gut tells you.  I will say that the risk associated with running your stem above the max height line is that the wedging part that is expanding the steerer is at the part where the steerer is weakened by the threads being there.  The risk is you literally pulling the top of your steertube off.  It's a really rare thing that those of us that have worked at shops have seen maybe a handful of times per decade.  That failure, though rare, is almost the fastest way to get your head on the ground.  So the risk is small, but the penalty is large.  I would not go more than a couple mm above the min insertion line.  

What I do have is empathy, as the process of buying, setting up and riding bigger Rivendells has finally led me to conclude that my custom racing bike is too small, and I'm parting it out.  I'm not saying that you should punt on your QuickBeam, but I am saying that I know what it's like for a good fitting bike to ruin another bike that had SEEMED to fit right for a long long time.  Best of luck with your efforts.

Thanks for the suggestion, but as the DD has an extension of 82mm,
that wouldn't be helping me. I could live with the bars being level
with the saddle, but a couple centimeters more extension would be
really awesome. I'm not even sure that a technomic has that much more
than a DD, but if it does, I may just go for the stem riser and
technomic option.

If only I had fully downed the Grant Petersen buy-a-size-up Kool-Aid
when I was a greenhorned Rivver...

Mike:

 

Think about using a Soma High Rider Stem Adapter, along with a threadless stem.  You'll get up to 60mm more height out

of the stem adapter than you can get out a Technomic or a Tallux, more extension that the Dirt Drop, and you can gain a

bit more height by using a stem with some rise to it.  And the Soma part is available in silver.  It will look more ungainly 

than the Tallux, but it might fill the bill for what you're looking for.

When I wanted to get my Noodles high enough on a 48 cm (19"), level tt, short ht mtb (my Herse was a 60), Riv told me that the 10 cm DD had by far the greatest height of any stem they sold -- they didn't sell the Tallux then, but the 10 cm DD was far higher than the TD or the T. I was able to get the Ns higher than the saddle with a lot of quill to spare.

Also, don't use your saddle to adjust bar reach! Get your saddle in the right place for pedaling efficiency and saddle comfort and measure all other component positions from the saddle.

This is what I was looking for: http://www.rivbike.com/Articles.asp?ID=326

It shows clearly the height of all the different stems they sell; the 10 cm DD is still the highest.

Here's another useful link for comparing the relative reach, height, and extension of different Nitto stems:

Well, according to RBW the DirtDrop gives me 82mm horizontal
extension, so that's not so appealing to me. I can live with the lack
of height above saddle, as it is my city fixie and I can roll with
what I'll call a "more aerodynamic" setup, but more stretch would be
really nice. It's sounding like a stem extension & technomic may be
how I need to solve this...

Mike,

Thought this might help.  Though, you might already have seen it:

RivBike Nitto Stem Comparison

Good luck!

Are you dead set on a quill stem? VO makes a nice quill to threadless
adapter. If you need more height, Soma makes a ludicrously tall
version. You would have many more options with threadless stems.
Again, VO has some nice options.

I'm 6' 4" and this will be my solution for getting a set up bars up to
saddle height on a sport tourer conversion project.

You're welcome. Glad to be of help.
