Stem Raisers

how do I work out the angle and will that also have the

Any thoughts, advice, wisdom greatfully received.

How about 5" risers?

You'll get the increase in height and be able to tune
cockpit length by rotating them.

One caution, the higher the rise on bars, the more likely
they'll spontaneously rotate during hard braking or braking
on a steep descent.

I used a three inch stem riser on a previous bike I used to
own. It raised the bars high enough for me. I had no problem
turning or braking. The riser I used looked just like the
one in the link you sent. Give it a try you will most
probably be satisfied.

Hi

I wondered if anyone has experience of using stem raisers?
I've got a Trek 4500 (2004) with Rock Shox Judys on the
front and I've been given (foc) some four month old Duke
XCs by a friend. I'm quite keen to install the Dukes but
the steerer doesn't quite give me the handlebar height I
want (in the region of 1 1/2 to 2 inches short). Two
options spring to mind: one is to get a new stem with a
different angle, in which case how do I work out the angle
and will that also have the effect of moving the
handlebars forward or backwards in relation to the saddle?
The second option seems to be a stem raiser such as (
deltacycle.comraiser.phpOpen ↗ ) the Delta
Stem Raiser which clamps onto the outside of the steerer
and the existing stem in turn clamps onto that. It looks
very simple in design, but the question is are there
significant drawbacks to using such a device and what are
the safety implications?

Any thoughts, advice, wisdom greatfully received.

All the best,

Dan

Those things look scary. Do you notice any flex?

He said he only needs an inch or two. No need for big
risers, unless he has risers already. Risers do seem more
stable than this stem raiser. As GT mentioned they look
awfully flexy.

The stem raiser would be nice if you want to be able to
change heights from ride to ride - e.g. I'd like to have my
handlebars higher for easier rides and lower on more techie
rides. Changing bars from ride to ride isn't a very
attractive option!

Yep. I made my old MTB into a cruiser by putting on some
3.5" risers. It did just that, one time - that's when I
realized I didn't have any tools on that bike (and I was
just riding around town so I didn't have my 'bak with tools
in it). I ended up riding a few miles with the bars
horizontal!

I can help with this bit at least...

habcycles.comfitting.htmlOpen ↗

That'll help you understand the change in bar position
(relative to the saddle or any other point on the bike that
isn't capable of moving much...) when you change stem rise
angle or extension.

the $695 ti frame

None at all. It was solid. When I broke my frame (which G.
Fisher replaced) and bought a new fork, I no longer needed
the riser since the new fork ( Mazz EXR Pro), compaired to
the old fork (RS Quadra 21R), made up for the handle bar
height difference.

All the best,

Dan - I use that very unit on my BASE bike, it's a solid
piece of kit, and mine has taken many knocks, on 2 different
bikes. Only thing, with mine I managed to strip the two bolt
threads out (very heavy handed as I am, and I've had the
part on and off heaps of times, too). I just drilled the
threads out (counter bored), and sank 2 x steel nuts in
there instead. Like I said though, that was no fault of the
part itself, just my heavy handedness.

Just as you say - solid as a rock. I haven't noticed any
flex at all from mine, even under the heaviest of
braking forces.

That's an interesting suggestion and not something I had
thought of. Could you recommend some 5" risers for XC riding
(nothing too expensive - i.e. no carbon)?

That's quite comforting. I couldn't *see* any reason why
a raiser shouldn't work but its rather safety critical!
I can't get this product via my LBS and I'm cautious
about ordering unusual products off the 'net. Thanks for
your opinion.

I think we've all stripped a bolt at some point! However
that sounds good in other respects. Stripped bolts don't
worry me so much I just wanted it know that it was safe to
use. Thanks for the advice.

I've been using one for several months, it is rock solid,
and really ugly. Be aware that there is a minimum rise, and
it'is more than 1-2 inches if I remember correctly.

I believe Nasbar has one, just like the one I used.
