stem idea

[proanti1]

okay, this might not work too good for mountain bikes, but may be a good idea for road bikes. i want to try to mill a stem out of plexiglass or acrylic stock, does it seem like a good idea?

It doesn't. Wouldn't it be heavier than a standard alum/carbon stem?

I don't klnow about strength but boy it would look cool!

Keep in mind you try to overbuild products for the worst possible scenarios: either repeated out-of-the-saddle exertions (over years) or a couple of crashes.

I think it would be too brittle.

[alexchannell]

bad idea, any stiff plastics I know of are quite brittle

it would look cool yes. but it would not work at all. Just the force needed to tighten the clamp bolts would probably be enough to introduce cracks. Maybe out of Lexan, but still I wouldn't try it, not even for road biking.

i agree... looks cool but would deffently sent some splinters down when you try tightening the clamp bolts. and even if u made it out of the "unbreakable" "allmighty" lexan it would do the same thing just after you tighten up the clamp bolts then go ride a few times. trust me lexan isnt as strong as they say it is. i use it on my robotics team at school and it says that a 4'x4' square can hold like 185~195lbs but i cant.(tried lifting a 180ish kid on it and it completly snapped after holding him up for 20 seconds)

It is true, it wouldn't handle the clamping force... I have 2 E-13 super-chargers, and both have cracks from the chain-ring bolts.
