Except on the one side where the bars twisted in the stem....

Less parts=less stuff to tighten independently=>less stuff to go wrong out on the trail.

I'm sure you can design something that will be just as strong as a one piece part, but in the real world, things aren't perfect. In other words, there may be inconsistencies in bar diameters, crown mounting points, thread, manufacturing tolerances, etc.

I like the transition for just that reason...when everybody else seems to want 5 different parts to make one stem, I'd rather see two.

im not to fond of the transition stem, it supper narrow, wouldn't that affect the torsional stiffness far more then the amount of pieces to it? i think a one piece face plate and two piece "mount?" would be stronger.

 

[kowekiller]

at least the carbon bars are still straight...

Ouch!!!

 

[kowekiller]

I was alittle worried about that too. But once you see the stem and bolt it up it super. Its really light and super stiff. Bars lined up with no problem and the price is sweet.

every stem feels stiff with no load on it. but since it is more narrow it getting more flex which in turn would that not increase the fatigue rate? i mean i know all the stems on the market are relativity narrow but wouldn't it make sense to increase the width?

For what it is worth...

Our direct mount is 48mm wide at the bar, and our regular stem is 50mm wide at the bar. The bread and butter Truvativ Holzfeller stem is around 48-50mm of contact with the bar (uneven width on that stem).

It is hardly "super narrow" but yes, it is not as wide as the fully seperate two piece stems.

I'll agree its not the widest stem. But its not as narrow as you think. Plus the bars are built really thick right in that area and start to taper right about where the clamp ends. So it wouldn't be all that great to extend the clamping surface to the weak part of the bar and crush it. You need a little bit of flex in all parts anyway to stop things from snapping right away.

nice piece

nice piece

Looks comparatively heavy and bulky compared to some of the others that have been posted, not a exactly a bad thing though.

170gr low profile and some meat on the bone!!

 

[Bikael Molton]

why does that Persist stem have 6 extra faceplate bolt holes?

it is wight save and looks cool..

 

[RedOne]

speed holes

 

[Bikael Molton]

cool is in the eye of the beholder...

I wonder if it makes cool/annoying whistling sounds as the wind blows through there while you are riding.

 

[bullcrew]

Thomson stem! Notice they engraved it for Jerry at hippi tech as well "hippie go fast" and an address on the other side as its not yet out.

Really disappointed in the Thomson stem especially considering how svelte and good looking the regular X4 is. To each his own but I certainly won't be buying one.

"really disappointed in the Thomson stem especially considering how svelte and good looking the regular X4 is. To each his own but I certainly won't be buying one."

I was not going to buy one either because it is not a good looking stem. But the more I looked at it, the ore I like what it does. It is light, lowers the bars and is a strong design. If they come out by march I will buy one.

 

[mullet_dew]

So on that Thomson, whats the point of the extra material that covers the crown bolts? Looks like a lot of material just for some aesthetics.

 

[al-irl]

probably just for asthetics but it works for me. It has some nice lines and am sure would look really sweet when on the bike. Nice and neat.

It took me a little while to come around, but I like it a lot now. Simple, clean looking.

Jerrys (hippietech) bringing it over to the shop tomorrow so Ill snap a few pics of it from different angles.
I like it it is simple and this is the 5th generation that Jerrys been testing over the last couple of years, thomsons work is second to none and definently take a bit to release stuff but when they do its done right.

You can say that again....
I have a few Thomson Stems and seatposts, and they are beautifull in every way......... Right down to how they function.
If that stem was a available a couple months ago I would have bought it.

yeah they make light but super strong stuff! Ive always liked there stems and posts, Im wanting to mess with with it a little Ill weight it as well (ofcourse lol) as get a pic of it. I dont expect it to be as light as some of the offerings but I do expect ot to be solid based on there x4 series especially the 50mm lineup for DH.

 

[samdemo]

so with the Thomson DM, if you wants to check the torque on the stem to crown bolts, you need to remove the handle bars? having said that, it's not like i check the torque daily but if a creak starts to appear.....

Yeah I could see that but overall thats not too big of a deal like a BB or other item. A little work never hurt anyone besides you will want to clean your bars and readjust them anywase! I know Im psychic OOOOAAAAAAOOOOO!

 

[Bikael Molton]

Wow lots of judgments on how the Thomson looks. No wonder we have silly light stems out there, if the primary concern is aesthetics.

I would trust Thomson's stems before the rest of these fly by night companies. It seems like a stem is the first thing manufactured when some random dude decides to start a component company in his garage.

 

[bullcrew]

I think they should make it so its reversible a raise direct mount or flip it over and be a lowered direct mount!
I like it a little extra material can be good. Just make some holes on the top covers and its a dual purpose depending on course!

 

[Carnaza]

It seems that the twenty6 direct mount stem got a little upgrade..

if you check the following photos you can see the difference... the face plate is a little wider.. and the "new" stem (purple) it`s a little heavier as well 140 grs v/s 125 grs (old one)

Po1nt pedals and stem are on order for me, cost a small fortune but I can't wait to get them...

 

[daisycutter]

You will like them. They are well made. The pedals are great

 

[Jase76]

I'll be running the same combo, I already have the stem but we've had a bit of a wait over here for the pedals. I'm really looking forward to giving the pedals a try. Po1nt gear is top notch.

 

[yetirider1975]

and I too have the same combo! you wont be disappointed!

 

[bullcrew]

I dont have the same combo and you will be dissappointed!!!! LOL
I have no idea, I just had to throw it in after the 2 posts above. Had to be a little different.

 

[frango]

Correct me if I am wrong... does Thomson DM stem hold h-bar with just 2 (two) bolts in the middle?

does this put your mind at ease?

Thx, this is what I... hoped

 

[Gary]

WTF?

is that Thomson plastic?

think I'd rather chance my luck with a couple of jubilee clips
