Options
(1) Stay with current stem and bars
(2) Get Redshift 30 degree stem and keep current bars. The stack and reach would stay the same.
(3) Get Redshift 30 degree stem and bars with a modest rise (e.g., 1.5 cm). [Redshift Kitchen Sink has 2cm rise.
(4) Get Redshift 6 degree X 70mm stem and Top Shelf 50mm rise handlebars. This would increase the reach by 1cm and the stack by 2cm.
(5) A Redshift 6 degree X 70mm stem and the current handlebars. This would result in similar to original stem.

How do I choose the right length and angle for my bike?
We put together a set of instructions that can help you determine the length and angle of your existing stem and provide guidance on what to chose based on riding style - check it out here.
How is the ShockStop Stem different from other suspension stems?
There are a lot of ways the ShockStop is different - so many in fact, we wrote a whole blog post about it. Check it out here.
How do I measure my steerer tube diameter?
The easiest way to determine your steerer tube size is to use a pair of calipers to directly measure the diameter or take your bike to the local bike shop and they will be able to measure it for you. Alternatively, most of the time a manufacturer will list this under their specifications in the Frame/Fork section. Make sure you are looking at the correct model year as these sizes can change year to year.
The 1-1/8" ShockStop Stem is the standard size used by most modern bikes. The 1-1/4” version can now be used on popular brands such as Giant and Canyon bikes.
