    My Custom made I-9 ( Infinity 29ER)

    All Columbus tubes@ fillet brazed
    Trail XC endurance geometry.....
    Mated with a Rohlof hub to become a solid working horse!!
    Got about 1500 miles on it.

    A dream in all aspects....currently building two more for clients/fellow riders (one is XXL).

    Internal cable routing is sick.

    I agree. Very clean. What's the third cable do?

    Question- Could the internal routing on the rear stay comprimise the strength? I have never seen three...just one.

    Rohlof uses 2 cables, one to shift up, the other to shift down.

    Cables

    Two for the hub gear change. Its a "pull-pull" cable method - no spring like open der. Third is obviously the braking hydraulics pipe.

    Those tubes are very strong for their intended job - condensing inwards delivering and absorbing energy to the top tube.

    That said the holes are round so there are no stress points. More than that the holes are brazed around with those leaf looking internal cable routing cowlings 1.3mm thick steel.

    And most importantly - its the " alloy of the legends....."

    No worries

    Sickbike! Have you though of using a monkeybone to replace the leverage arm of the Rohloff?

    The cable routing is the highlight of this frame, even more so than the rohlof drivetrain!. is there access to the seatstay through the seat tube with the post removed?

    Notice the seatstays do not connect to the seat cluster symmetrically.

    I'm not personally a fan of internal cable routing but this bike looks nifty.

    Why doesn't you build your frame with OEM dropout ? That will be more discret than a long torque arm (until on a custom frame !) ...

    sweet bike....

    I love the internal cable routing. Do tell about the geometry and ride quality.

    I was a bit worried that the paragon drop outs are not designed to take so much torque.

    But i am thinking of taking the next go with a monkey combined with a EBB and a belt drive.

    Make the "infinity" even more infinitive .

    And I would not dare take material out of the seat tube at that specific point.
    Not worth the integrity of the frame loose at that area, Just to have access.

    The cables housings just slide down from TT to SS.

    I am an Industrial designer but had to consult with a talnted friend - a goldsmith jewelery maker regarding the precise distances between the cable opening and have those in precise composition regarding the fillet brazing tube proportions.

    He had his say and that was that

    looks like a great bike, the internal cable routing is just......beautiful. Do give us some geometry numbers and also curious about the weight with the rohlof hub

    Good job! spec

    bike is 12,7 kgs if i remember the exact number
    Building custom bikes methodology at my shop starts with wheel base
    in proportions with height torso and inseam

    Its a 1905 mm wheel base a 71 deg on head angle and 436 mm chain stays - rails on tech descends fo my height . With no derailleur and chain rattling all over the frame, feed back is just awesome. Riding position is a bit high for dedicated performance bike.
    Some riders would prefer a lower BB (in about 23 mm) , personally i like sitting high on those open fields.

    Thanks for all the replays and feedback!!

    Awesome. I really dig the internal routing for everything.

    Beat me to it. The torque arm is am eyesore of epic proportions. Paragon makes a left side dropout insert for the sliders in that frame that gets ride of it. And like you said there is always the dog bone.

    Will do

    A Shimano Alphine hub might be in use on this frame , so not sure the internal cable routing should be the same due the cabels having to run on both
    sides of the frame with the alfine. So another design would probably be implemented.

    It will be fillet brazed for sure though.

    Thanks.

    Phisicswise, as mentioned by others,
    It makes sence to remove the torque forces
    away from the axle an dropout.

    I have to hand it to Rohlof for doing an amazig job, torque arm or not
    This thing puts the whole bicycle gearing industry in a
    prespective. Very important company for all of us.

    I had not heard of this Rohlof hub and thought "man, why arent there more of these things out there."

    Then I did some quick searching and found out they are something like $1700 bucks.

    While that replaces a hub, cassette, shifter, derailleur, front shifter and derailleur, I am not sure it's $1700 cool. .

    You can get them on ebay for ~$1000 or so.
    But do consider the fact that about 70 % of the open gearing dies
    Within a year....every year.....its a very costly method.
    Their fragility is stricktly the coperatives intrest, to make
    us consum and consum. ....

    The Rohlof lasts forever.

    Beautiful frame. How do you keep the water out of internal routing holes to prevent rust? Is it treated?

    Very cool

    And with all the thought into running all these internal cables, I would have expected the front brake cable to be inside the fork to prevent damage and not "hanging out" as it is...

    Hey thanks
    Oil based treatments left to dry befor assembly
    And anual treatments as well driping in with a 15g
    Needle.
    A touch or rtv at openings on the top tube.

    Totaly none issue

    You can get away with wd40 every six months
    forever on bare steel tubes on on non exposed parts especialy with good ventelated
    frame openings.
    Frames left with just welding gas holes should be looked
    with more attention to my opinion.
