    Will there be a trade-in program too ?

    even so the frame flexes much less than aluminium frames the clearance for 4.0 tires is to narrow for upphill.
    the frame was designed for the 3.8 Larry maximum

    5" frames will be presented at unicon

    cheers jogi

    Hi waaalrus,

    Both my regular wheel and test wheel are symmetrically built. And it would really be bad luck that two different wheels have the same tension imbalance (hence the comparison).

    I will try again by paying attention to the bearing caps but I don't remember having trouble mounting and tightening them...

    I don't think that pulling the frame arms apart to get an inflated 4.0 tire in would have any impact, wouldn't it? (it is titanium after all!).

    I will keep you posted with pics

    Context:

    A Triton Triple frame with a 65mm rim and a 26x4.0 tire. When riding, I get some tire rub on the right side.

    Wheel trueness is out because I was able to try a second wheelset in (same side for the rub). It could be tire deformation but I guess it would be consistent on both sides (especially when cranking hard) and less a problem at higher pressure.

    With a Surly Nate 3.8 27tpi @ ~ 30psi: rubs on the right when cranking hard
    With a Schwalbe Jumbo Jim 4.0 SnakeSkin @ ~ 30psi: rubs on the right almost all the time

    Questions:
    • am I just unlucky and the Triton Triple has a clearance so tight that I am out of luck and should get used to it ?
    • or is it possible that the frame has a problem (not straight or flexing) ?


    For reference, I have been running with the Nate in this frame for a while and I only noticed some rub recently.

    Thanks in advance for your input

    Hi Jeff (mountainuni1, right?)
    Thanks for your response
    Right - my concern about using a 180 rotor is that I believe it will rub the frame as the legs of the triton are not straight but angle out slightly. With the 160 rotor pictured a few posts back I got just about 2mm clearance but if the disk grew even a little in size this clearance would decrease to less that 1mm. Too close for comfort.

    I realise your UCM works with SINZ 180 rotor and nothing smaller... I assumed that this would be it wouldn't with with Spirits using 160 - or have I now got that wrong? From your response I guess I have as I now can't logically see why KH spirits and a 160 rotor and the UCM wouldn't chum up happily together and play ball if I have then I'm happy to get the UCM and use it with the KH cranks, and do a little filing to get it to fit. Sounds like a nice option.

    I saw on your site a picture with a diagram of the UCM and there it did state that it would work with 160 to 200mm ISO adapters, but I got a tad confused as others had stated (as does your site's main info) that 180 was the minimum (but I guess they were talking just about SINZ)

    So when it comes to placing an order I should just do it via your website? How long does your international shipping take to Czech?

    Thanks for all your help
    Felix

    160 vs 180 issue and UCM v2 not in the works

    Hi Felix, No V2 UCM is in the works, if it ain't broke don't fix it. Not really understanding the 160 vs 180 issue. The diameter of the rotor shouldn't affect any frame rub. On some applications, I have found the need to shave off the inside head of the CRB's that come very close to the frame stantion, even with a 6mm spacer. But my kits only use 180 rotors, as that's what was fabricated to mate up to the SINZ 5 bolt cranks. If 160 is the biggest you want, then the KH Spirits is likely your only option.

    I see, thanks - I wasn't actually concerned about the UCM stressing the bearings. I was just curious about the off centre alignment of this older triton frame, and before that a bit about getting disk clearance with the splayed out frame legs of the triple. But now it all looks set to be possible and I see that UCM is the way to go. Did you get my email about ordering a V2 UCM? The max size rotor I can run will be 160mm as anything bigger will rub on the frame.

    @bouin-bouin - thanks for the clarification

    Cheers

    QUOTE=mindbalance;1644573]@bouin-bouin

    Here is a close up of the bearing cups. I suspect I do have the off centre version of the frame. I can see that the bearings are not in line with the bolt holes of the frame.

    What are the downsides of this set up? Apart from problems with disk brake set ups using UCM or d'Brake. Are the bearings under more stress seeing as the frame isn't centred above them? Does this arrangement mean a weaker set up overall?

    I am curious what the thinking was behind this to make things this way...

    Thanks a lot

    It'is better to have the bearing in line with bolts for bearing stress but not an issue with Triton frame as bearing holders are machined with precision. Your frame is corresponding to original design, Macduni attapted a Dbrake on such frame but not easily

    Photos regarding disk clearance on Triple.
    It just about clears the frame when crank is mounted with a 6mm spacer. I get around 2mm. If I were to use a 180mm rotor in stead of the 160mm I believe the disk would rub on the frame. It could all be solved with an 8mm spacer moving the crank out a bit more, but when I put one on the remaining axle looked way to short.
    -- Am I right in thinking there should be enough axle to go all the way into the crank splines (up to the space were the threads start for the removal bolt)?

    @bouin - thanks a lot, yes I will take out my wheel later this week (away now with work) and get a close up pic of the bearing mounts. Curious about this...
    Maybe Maguras would be the simplest way to go, but I would like to get a disk option working with this lovely frame and LM wheel

    Cheers

    @bouin - How can I tell what version of the triple I have is? And regarding holes, do you mean on the D'Brake/UCM - they they need some modification, or is there something "wrong" with the older frames that was later corrected? Thanks a lot

    Felix
    Older Triton had the holes in the middle of bearing cap and not in the axis of the bearing, Macduni had this issue. Can you put a close photo of your frame ?
