    V2 OPI Steerer

    V2 OPI steerer has arrived.

    Hope it solves the creaky/flexy V1 OPI stem issues.

    I would too . . . if it were JUST a creak. But the V1 stem flexes/pivots from side to side when torquing on the bars or hitting gnar. I can see, feel and hear this whenever I get on it. Drives me batty. Can't tolerate it. Must fix.

    A new conventional stem and steerer is way more than $75. So . . .

    But you are right, C'dale should make this a warranty/recall item, as the V1 was clearly a defective design. At least offer the fix "at cost". A whole new stem is only $110.00.

    Dam,
    I paid $80 for my entire V1 OPI stem. It does not creak. So, I'm just going to wait.
    Lead by my Lefty............... right down the trail, no brakes.

    if it's as bad as all that, then you are 100% correct - they should sort it for you.

    mine has be good thus far, but i only ride xc. it sounds like you give it a good workout!

    good luck!

    Yeah, I think I paid about that for mine at like Bikewagon or something. was creak free for maybe the first 250 miles or so, then started in and has gotten progressively worse and flexier. Prolly needs to be re-torqued if not re-installed w/ fresh anti sieze. But obviously, the root cause is the poor design.

    500 miles of hard singe track on mine and not a peep....I suggest re torquing and re lube is in order if yours makes noise.

    Yah - there are countless threads/posts of people repeatedly doing that to temporarily fix the creak/flex of the OPI stem.

    It's a very poor design, which is why it got redesigned in short order. Hopefully, the redesign is a permanent fix, as the stem is not exactly easy to remove and relube/install.

    My '13 scalpel just arrived at the shop, the first order of business is to see if it had the V.2. This would be great as the V.1 on my '12 was a pos and I replaced it with a fatty steerer and stem which solved the problem of flex and creak, but it looks retro and the new stem looks much better. Besides on a bike at this price point I shouldn't have to swap out parts like that.

    Thanks for showing it...That new design does look a lot better. The base of the stem is now locked against the top inner spacer, so should be a lot more solid than merely having the steerer thread hold it in place. That steerer thread is a very fine pitch and hauling on the bars puts an awful lot of leverage onto it.

    I am glad they continue to improve these things. A free trade in for our old steerers would be nice, or yes, "at cost" (can't believe that would happen unless it's a safety concern, though).

    By the way for any UK guys (like me) you can get them at Qwerty cycles as below. The pic is the old one but Qwerty said all steerers are the new design now:

    Just ordered one - Great price at £19.00 too!

    Update: V2 stem installed and ridden - It really does feel a lot more solid, much better. I'd recommend it if you don't like the "play" or creaking in the current one.

    My LBS lubed the steerer tube on my 2013 F29er 1 and while it reduced the creaking, it did not fully the resolve the issue.

    I agreed to the repair only if Cannondale (or the LBS) agreed to upgrade the component if the lube did not work.

    My LBS has ordered the upgrade and it may be a few weeks until the part is delivered...

    Yeah, I pulled, cleaned, lubed mine a few weeks ago and all seemed pretty good, except for the continued "flex". Today, it began creaking wicked and wildly, again. I put flex in parens because the 2 pieces actually PIVOT on one another. Its not really stem flex. The flex comes from the lefty top clamp and the upper headset bearings - the only things keeping the stemp from pivoting freely.

    There is just way too much movement at the interface of the 2 pieces. Once the lube gets squeezed/washed out and/or contaminated, it creaks like a mutha as it pivots.

    Can't wait to get the new steerer installed.

    It's interesting how different people have different experiences with the OPI stem. I've had one on my RZ120 for about the past year or so and have well over 1000 miles on it and there has been absolutely no creaking whatsoever. During this time I have not disassembled or re-greased the bearings or threads. I would still like to get the V2 model just because I like having the newest stuff.

    hi! can you please tell me if I have V1 or V2 OPI steer by just this pic:

    http://i47.fastpic.ru/big/2013/0522/...fbb706244f.jpg

    or there is no chance to tell that by this picture ?

    Sunny_12: Sorry, you can't tell from that angle.

    You need to look underneath the head tube.



    You see the bit this guys has in his fingers? That sits underneath your head tube. On the bottom of that are some small white numbers / letters. If it's a V2, it should have "V2" printed there amongst some other letters probably.

    Yeah I think so, I can't remember if mine said "V2" or "Mk2". I'll check but don't think I'll be around again until next week to post but it sounds like you have the newer one anyway...

    Make sure you plug the bottom, dirt gets in it and works it way up. That's the main cause of the creaking

    Hey guys, Just thought I'd pipe up here.
    I'm a mechanic at a Cannondale shop, and have been working on a few customer's bikes with the OPI v1 creaking issue.
    We've yet to receive any v2 replacements yet, but I wanted to share some things I've noticed. The commonality among the bikes that have has issues is length of stem. No 90mm stems have been noisy, just the long ones. Basically, the amount of leverage seems to be deforming the threads on the steerer. We've replaced a couple of OPIs in favor of the old-style one piece steerers- problem solved!
    As soon as I get some v2 assemblies on customer's bikes, I'll report back.

    Los
    Whiskey is my yoga.

    It has printed "134 MK2 RB1" on the bottom... could that stand for ver. 2 ?

    Yep "mk2" are the magic letters to look for on the V2 steerers.

    A few weeks after re-installing my V1, it began to sound-off once again.

    So I just installed my V2. Seems more solid w/ less torsional flex with just just applying pressure on the bars.

    The threads on my 90mm V1 were definitely deformed, presumably from all of the movement between the stem/steerer crunching the threads and any grit in between.

    I agree that a lower steerer tube cap would be a worthy mod. Tons of crap quickly works its way into the greasy threads of the assembly. If anyone discovers a plug-n-play option to cover the hole, please post up. I am contemplating spraying some expanding foam in mine! LOL.

    I think folks w/ a '13 bike want to know how to tell if their assembled bike came with the V1 or the V2, without having to disassemble the stem/steerer. The V2 is marked with "MK2" on the bottom underside of the steerer.

    The 2013 bikes have not been equipped with the V2 steerer unless it's an XL headtube and Lefty clamp spacing. An easy way to check is that the first style steerer has a synthetic flat shim just above the BB tool interface area. The V2 steerer uses a rubber O ring there instead.

    That's what the C'dale product update information sheet (tech note 130197) that came w/ my V2 steerer says.
    "The new steerer item has a shoulder and is easily identified by "MK2" laser etched on the bottom."

    BTW, the other digits laser-etched on the bottom are a date code and headtube length in mm.

    but i guess i don't have a rubber o-ring down there.. as well as there is no synthetic flat shim .. i should check that tonight back at home .. maybe in the shop they did forget to put that on..

    i am having strange sounds: DSCF0729 - YouTube

    I thought it was from lefty.. now i am thinking about steer and inner spacers

    should bring it tomorrow to a local service

    The O-ring is necessary, otherwise the steerer will be able to move up/down in the headtube a few mm.

    thanx, Stumpjumpy, now I understand that at the shop they mounted it incorrect. In the C'dale lefty hybrid 2013 manual page 11 there is a scheme with I guess old V.1 steerer and it shows only 3 outer spacers and no inner spacers. Do I understand right that V2 goes with inner and outer spacers, while V1 goes only with outer spacers ?

    here SCALPEL 29ER CARBON ULTIMATE - Scalpel 29er - Full Suspension 29er - Mountain - Bikes - 2013 is no outer spacers also..

    i am getting a bit confused.. the scheme http://icimg.com/kh058doc.jpg says, that if there is 3 + 1 (red) spacers inside = there should be 3 spacers outside. Now I suppose that at the shop they put all spacers outside and no inside..

    well, tomorrow will show... if there is lack of outer spacers, can I buy it somewhere ?

    Stumpjumpy, please, what do you think.. if I have http://i47.fastpic.ru/big/2013/0522/...fbb706244f.jpg only 2 black and 1 red spacers and nothing more.. the correct way is to put 1 black + 1 red inside, and 1 black outside ?

    you are helping me very much with all this stuff !

    The spacers just adjust stem height. All are optional, except the chamfered red one at the base of the steerer's shoulder, which is required. If any additional spacers are used to adjust height, an equal amount have to be used on the lower (internal/invisible) and upper (exposed) portion of the steerer.

    I suspect the sound u hear is the upper spacers rattling around because of the space created by the absence of the lower O-ring. Can u move those spacers around by hand, or are they tightly sandwiched in there?

    Alternatively, there may not be the correct number of lower/internal steerer spacers used, allowing those to rattle around freely (and also defeating the purpose of the V2 redesign).

    now the picture is getting clear !

    I can move them around easy ! well not like the wheel of fortune , but I guess you know what I mean ! I tried to cover them with my hand while shacking the bike - but the sound didn't disappear.

    Now I think I understand why my arms get tired , i think I have unnecessary spacers up outside !

    I feel some relief =) I guess you helped me to find a problem with this rattling sound, you showed me an incorrect positioning of these spacers and i hope the reason for my arm ache =)

    tomorrow I am going to the service and tell them what to do, after that i hope the problems will go away..

    If the sound did not go away when you held the spacers, then it is likely the lower/internal spacers that are rattling because the correct number were not used.

    Take it to the shop and when they pull it apart to add the O-ring they will see if a spacer is missing.
