I'm considering raising the captains handlebars on my Burley above what can be accomplished with a stem change. This means a stem riser such as Delta, Dimension, or Zoom. I realize it's only one more connection of the steering mechanism., i.e, stem -riser-steerer versus just stem-steerer.

Given the increased weights and dynamics of a tandem, does anyone have any thoughts about safety or is it anymore of a concern than it would be on a single bike?

Has anyone installed or used a stem riser on a tandem?

Thanks.

Have you considered a high rise stem like this one?

What kind of steerer tube? How many cm of spacers are you running already? I would check out your proposed setup with the Fork manufacturer, and the manufacturer of the riser.

And I'd be very leary if the steerer is CF. (other than the Alpha Q tandem fork that is designed for a lot of risers.)

What brand of stem is that? I have a Dimension adjustable on right now.

Merlin- Steerer is cromo.

Give Mark at precision tandems a call... if it is possible and safe... he will set you up.

Yes. They work fine. A stem riser is subject to its maximum stress from a strong rider pulling on the bars in a climb, and that's the same on a tandem as it is for a single. No more concern necessary than on a single.

Same here. We run a Satori (aka Zoom and other brands) on a Cannondale Road Tandem. It's absolutely as sturdy as a 'normal' stem would be.

Yes it's safe (if properly installed).

Thanks everyone. I was in the big city for a couple of days and I have picked up a Delta riser. When I get the Burley squared away I'll post a pic.
