BBB Stem Extender

The guy at the bike shop cut my fork a bit too short on my LHT due to a language barrier (I'm in Korea) I have been making due with a very short 70 mm stem with a 35 degree rise that works pretty well. I would still like the cockpit to be a little closer to me though. Its possible that I just need a smaller size frame and that I may just need to either get used to it or go down to a size 50 frame. However, thats expensive.

I am wondering if I used a stem extender like this if it will be able to bring the bars further towards me because of the angle on the steerer tube. This in combination with flat and short stem maybe enough to get the bars just a little closer in to me.

Is this a piper dream or should I try it? I am pretty comfortable on the bike up to about four or five hours. Then my arms get tired and sometimes my upper back is a little sore later. This could just be that you can not spend that much time in ANY riding position without being a little soar or it could be that my top tube is a little long. I am not sure. I can post pictures of my riding position if you think that would help diagnose the problem?

Here is a link to the stem extender:http://www.rei.com/product/804413?pr...:referralID=NA

It looks A LOT nicer than the clamp on ones that I have used before. Are the clamp on ones better for some reason other than just being a little easier to install?

Thanks for the help guys, as always its super appreciated.

That appears to be designed for a threaded steer tube and threadless stem... iow an adapter and extender. If I'm reading it right, it won't work on your threadless LHT steer tube.

I think dcrowell is right, the product you linked to won't do what you want. However, I think this might:

It will bring the bars higher up, but not really much closer. However, higher bars might make you more comfortable, even if they aren't much closer.

Good luck,

Chris

Because of the angle, bringing the bars higher also brings them a bit closer. I use one of these risers on my Trek 2300 and like it very much, especially since I want the bars higher than I can get them with stock components.

The product I linked looks a lot like a quil stem system but if you look closely on the package it says that it works with threaded AND threadless forks. I will try and take some pictures of my bike a bit later tonight and post them for reference. I don't think I want to raise my bars anymore than they are because they are already at the same height as the saddle. However, I was able to get them that high by a very steep and short riser stem.

What kind of bars are you using? Assuming flat bars, maybe you could try a butterfly bar (this sounds like it would help your comfort problems...)

If drops, then a steertube extender plus a shorter stem could bring the bars back a bit.

Incidently, if it were me, I would use the BBB extender, it looks like a good design, but make sure the inner diameter of your steertube is the same diameter on the package...

I am using the stock compact drops that come on the LHT. I used butterfly bars on my last bike and it was.... ok. My hands went numb a lot I am did not like having my arms spread so wide. I like the drop bars a lot better. How about mustache bars? Do you think that might help?

I use an extender to raise my Nitto 135 Randonneur bars, and an adjustable stem for the same reason. Works for me, but not as pretty as your linked one.
