    New question here. Syncros slanted stem caps.

    Does anyone know of a store or on-line location that still has some of these? If not then has anyone ever come up with a workaround.

    There seems to be a school of thought amongst some wrenches that I know that the stem cap is necessary for headset compression only, and that a properly tightened stem will not slip even with no cap?

    try syncros

    Contact Syncros directly. I asked them a few years back, and they sent me a hard plastic one free of charge. They said they didn't have any alum. ones left, but this was the alternative. Good luck.

    That's my line on it too.

    They are way too weak to have any structural ability. Ask anyone who's blown the bottom out of one cause they had no idea what they were doing, it doesn't take much at all.

    I'd leave it in, to keep the crap out, but yeah, once the stem's tight, if you're of a mind, it could be removed without incident, no idea why someone wold, but there you go

    Gotta be one of the worst stem designs ever.

    Post a pic w/ & w/o the cap and the cap itself - if possible...

    Depending on how much you think they are worth, you can often find the entire Syncros stem with plasti-cap on eBay for $20 or less.

    I seem to recall they came out with an Al cap after a while.

    Bonking ... not feelin' well

    I have a stem on my desk with the same dilemma. Was tinkering with a design out of alum that would suffice but since I don't what the original looked like, it would probably not look right.

    I will post something up if it works.

    I can post a picture of an original alu one when I get home if someone doesn't beat me to it.
    Need: McMahon brake for roller cam mounts, Mountain Goat fork.

    doesn't help much but chainreaction had repro aluminum caps for a while but are now sold out. just saying that they can be reproduced and don't need to be very expensive. but i'd look for a cheap stem with the cap. odd sized stems tend to be reasonably priced

    That would be great if you would not mind.

    Ooh, that's not something easily reproduced either... Not impossible though... It's a three step job, creating the base in a lathe (green), the next sawing the top (blue) in the correct angle and lastly 'manually' adapting the top (red)


    ...easier to buy one I guess, hehe...

    Could be cast in resin quite easily if you had an original to make your form.......

    Or, just cut a tube on angle so that when placed on the top of the stem steerer, it's 90 degrees, and use a 'regular' top cap. If the adpter/spacer thingy wouldn't sit properly, then turn a 'regular' top cap with a long enough plug to align the stem with the angled adapter.

    God, 'designs' like that piss me off. And syncros was so snoby about their stuff too.

    It's also kinda fun w/ stupid designs... Like the clutch on a Land Rover 'Series' car (1948-1984). So you wanna service the clutch. You open the repair manual and read the first step: Remove the front left fender... Easy thing, it won't take more than 5 hours (and the same to put it back on) - oh, and you'll need to repaint the car...

    I've had a couple of those... So now I play with mtb's again, hehe...

    Many years ago

    Syncros sent me a handful of little stem wedges that allowed you to use a regular top cap. They looked just like what Schmitty described.

    Nothing a black Sharpie couldn't fix. It's an ugly stem to start with...

    regarding riding sans top cap, headset seems to loosen in my experience. Doesn't seem like it should, but it did.

    what's with that three step job? Seems like it should be one step like the one shown by mtpisgah.

    I have a NOS 1 1/8" plastic, slanted Syncros stemcap. Says "Made in Canada eh!" on the top. Never installed.

    Want to trade for an XT U-II brake or 27.0 Syncros post (with hole at bottom of shaft) and I'll throw in some cash to make up the difference. PM if interested.
