General Cycling Discussion - OCLV carbon sole repair

I have a second hand pair of Nike Hautacams. I noticed that the heel on one of the shoes is coming unglued from the sole.

After surfing around there does not seem to be a clear fix. Aside from taking the shoe to a cobbler does anyone have any thoughts about repairing this?

Buy the glue and DIY? http://www.quabaug.com/barge

I did not see one that dealt with carbon or synthetic leather. I emailed them though.

Thanks fiest.

their change to less volatile solvents, removing the toluene,
one hopes, doesnt reduce the adhesion..
Toluene is the active ingredient in the glues I used, as a kid,
to assemble those [styrene] plastic models.

(but catalyzed epoxies are a different material, a chemical reaction..
they don't un combine, once mixed and cured.

MEK is another solvent. where 'a well Ventilated work place' matters..

the surface preparation before you apply the glues will matter.

but I expect with all the bikies in PDX , some shoe repair shop
will be willing to take it on.

I went to Dorian's in downtown. He has done similar shoes and can fix them, however his experience is that carbon soled shoes will become unglued at some point due to the forces involved and the stiffness of the sole. The weakest point will break which in this case is the glue.

I paid $20 for a $150 pair of shoes. So if I have to put another $30 into them I am still coming out ahead. Problem is that he is booked until June.:eek:

So he said to use a SMALL amount of shoe goo because it is easier to remove than acrylates. I am only worried about water getting in there and causing more damage. Here is hoping.

I'm not a racer type, so I get out my LL Bean Rubber bottom boots this time of year...
heck it's going to rain until June, anyhow..

Yeah I got my booties ready. It gonna rain til June which is why he will be busy till then. Bonus is that he may be able to put some new SIDI replacement heel pads on the shoes for me. I think they were made by the same factory.

UPDATE:

I shoe gooed my sole over the weekend and let it settle with a 100 pound weight on it. It appears good and solid. Time will tell and the first ten miles went well with no separation. I used very little about 1/8 tsp of shoe goo that I squirted from a syringe.

So here is to another 10 and another. Hopefully this will get me by. Oddly, when I emailed Sidi they asked me to contact Trek because Trek has more experience with OCLV carbon?! I emailed Trek and they were not that much help, but they bcc'd Vibram and Vibram got back to me.

Vibram does carbon??? I told Vibram what I did and they asked me to keep them apprised of the situation.

FYI - You cannot resole a FiveFinger KSO. I asked.

OLCV is a technique they build the frames, by, Trek, Their term..
You may be misusing the acronym , Sidi is cueing on that , perhaps ,
by mis-applying it to shoes..

I paid $20 for a $150 pair of shoes.
now you know why they got rid of them..
May have gotten value just from typing for a week, about them ..

Treat it like a boat repair perhaps?
Grind off across the crack , leave it rough.
mix epoxy , and lay some more carbon cloth across the gap
get out all the air bubbles.. Vacuum bagging is one technique,
then let it cure.

The shoes actually say OCLV on the sole. Optimum Compaction, Low Void.

I bought them barely used. So a little money for shoes that will out last me. I am cool with that. Not real sure I want to go grinding on my shoes.

Oddly, since that is a Trek term, could Nike shoes have been made by Trek??? The mystery deepens.
Bum Bum Bummmmm!

I got a pair of MTB Shoes made for Nike, In Italy, most of the stuff is Pac Rim.

why not go down to Nike HQ, in Beaverton, since you are in metro PDX,
see if they have any help in the Prototype department.
where they developed the contract specifications,
followed buy their various vendors.

Optimum Compaction, Low Void..
yup, I expect that got the air-bubbles out.

where can I get some Black Lorica? my favorite toe clip touring shoe
had a lace covering flap, i'd like to add that feature to some SiDi touring shoes
just an inch of attachment, and velcro where the lace holes attach..

a square foot would be enough..

Black Lorica??

Deek and Brians next adventure downtown here has second hand cycle shorts for cheap. Could use a pair of those.

not Lycra, .. Lorica .. is the trade name of the Synthetic leather SiDi uses.
I'm looking for that faux leather like the rest of the shoe ..

How is your shoe goo repair holding out? I want to choose a good type of glue that holds up well.

I have a similar pair of Nike OCLV Team Discovery model shoes which are the best fitting shoes on the planet (for me!) and I will be trying a similar repair. Mine has a rivet in the heel where the striker pad is. That rivet has pulled out of the sole of the shoe. I want to re-glue the heel and screw the two back together after glueing. After the glue is dry I will extract the screw and pop in a rivet.

Thanks - Jim
