Hoping for some advice Please. I've been given a 2001 Specialized M4 Stumpjumper that has had most of its components replaced. The problem is, it is currently running a 6 degree rise 1300mm stem that just feels too low when I ride (Original spec is 120mm 10 degree rise.). I feel like I'm craning my neck up all the time and feel that if I were only an inch or so higher this would help enormously. If it is an aheadset setup and the fork steerer has been cut to size, I can't use spacers, can I? So, is the only option buying a new set of forks and leaving more steere length so I can fit some spacers for more height?
Well, you could of course try a Riser Bar, perhaps combined with a new stem with a large degree rise.
Or you could try a Aheadset stem riser. There exist several such products:
Satori Heads Up:
Delta Stem Raiser:
Both are clamped onto the fork exactly the same way you clamp a stem to fork. The advantage of this system is that it is very easy to install. The disadvantage is the new minimum height for the stem, and perhaps a slightly funny look, if you put to many spacers above the stem. So this system isn't so flexible.
BBB has another type of stem riser, that works very much like the old quill stems.
BBB BHP-20 Extender Sizes: 25.4mm / 22.2mm. / BBB BHP-21 Extender Sizes: 28.6mm / 25.4mm.
To install this, you need to:
Measure the inside diameter of you fork, so you can get the right size of stem riser.
Remove the so called 'Star "Fangled" Nut' (some call it a Spider) in the fork. (I took a piece of broomstick and a hammer, and moved the Star Nut down the fork tube)
Buy extra spacers (the silver "spacers" you see on the picture determine the height of the stem rise, so you need to place real spacers around theese.)
Know how to adjust your headset (I have a Campagnolo Hiddenset system) to remove play.
The BBB system is slightly more troublesome and intrusive to install, but has the advantage that it is easy to adjust its max height (meaning no spacers above the stem), and perhaps no minimum height. It is also cheaper than all other stem risers I have seen.
Whatever system you choose, watch the cable length. I can just about get my stem and bar unto my stem riser without stretching my cables too much.
I installed a Satori stem riser today (I had actually bought the BBB riser, but it turned out to be the wrong size). The steering and riding experience becomes rather different; much "slower" and much less "sporty". Perhaps a shorter stem could cure some of this.
