Hi All

I kind of new to all this road biking stuff and last year bought a Specialized Allez. I want to buy a new stem for it and was wondering what size I would need? I only ask as it has one of those comp set stems with the adjustable angle shim and I just though to myself that it might not be standard size.

Cheers All

    I was considering changing my shoes. The pair I have now are okay for walking to the pub, but struggle to maintain a good pace while shopping.

    What size should I get? I had been looking at a pair in tan, but they were only available in a size 11. I think a black pair would be much more suited to the type of walking and standing around that I intend to use them for. A friend of mine has a pair size 8 and he says they're really good. What do you think?

    Opinions appreciated. :wink:

    there are different models of allez, no idea if all have the same size comnponents

    if you can find your model on the specialized website, look at the specification and it'll tell you some important info...

    is the steerer alloy or carbon, i think it'll be aluminium

    what's the steerer diameter, probably 1.125 inches (1" 1/8), you can measure this

    what diameter are the bars where they are clamped

    what are the bars made of, alloy or carbon, again i think al

    for instance, on the site, one model allez says the stem is...

    Specialized Comp-Set, 3D forged alloy, 4-position adjustable, 4-bolt 31.8mm clamp
    and the steerer aluminium

    (which sounds like yours)

    once you know steerer size/material and bar size/material, you can look for compatible stems

    Perhaps it would help if you mentioned why you want to change your stem. :wink:

  • Allez stems - all 1 1/8" standard steerer tube so that`s easy ! 6 degree rise (unless you`ve got one of the adjustable Comp-set / Pro-set stems, which you have, which have various adjustable angles )Then, the length of the stem is governed by what size frame you got? 52 has a 90mm stem, 54 and 56 have 100mm stems, 58 has a 110mm stem and 60 frame has 120mm stem.

    What`s the reason to swap it? weight? Looks? Bored with it? Buy something fancy in carbon, and swap the `bars while you`re there :)

  • Thanks all. Even for the response about shoes!?!? :shock:

    I have the 4 position comp stem and want to replace it for a 0 deg stem if I can find one. The lowest +ve angle I find too high and the smallest -ve angle a little too low. Also, I wouldn't mind something that looks a bit better too!

    I don't think I made my question clear enough. All I wanted to know was if I had a smaller steerer tube on my forks to accomodate the shim for the stem. Having taken the advice and looked on the Specialized website it does have a 1 1/8 steerer tube.

    The details should be written on it. It's almost certainly 1 1/8" on the steerer and 31.8mm on the bar clamp. Probably 6 degree angle.

    Carbon stems generally don't make a lot of sense, they are heavier than alloy ones and more expensive.

    As to length, as long as possible and slammed down on the headtube is most Euro but you should probably heed skyd0g's posts on that matter.
  • Run a standard 6 degree stem, then adjust the steerer spacers to put the `bars where you want `em. Once your back gets used to the position you can remove them in small increments as desired.

    I say 'shoes', but that's only so t' Southern softies could understand, tha knows. What I meant were 'clogs', but not them hobnail ones that we used t' ave. I were thinkin' somethin' more streamlined like. Mabbe wit' hobnails o' titanium, or suchlike. :wink:
