Sugru Moldable Glue

I first read about this stuff in the mechanics subforum and then watched some youtube on it. I bought mine on ebay. It comes in different colors, and I read you can mix them for a custom color. I immediately thought it could help save a couple of my saddles. This Turbo, I picked up for $5 the other day.



After some Sugru, it looks pretty good from 5 ft.



I used surgical gloves during all this!

That Turbo was ripped all the way around. I was a little too liberal with the stuff on the non drive-side. It's good for a flip bike now. I have another Avocet Racing that just had one little rip I had repaired with a piece of tape. It looks great now with a little bit of Sugru in its place.

You can do all kinds of home projects with this stuff, but I'm not really into all that. The only other thing I've done with it is to put it around my grocery pannier hooks where the original rubber and my occasional tape applications were not holding up.



Once you open a package and expose the stuff to air, you have to use it all within an hour or so, I guess. So get 2 or 3 projects ready. I would think torn brake lever hoods would be another good use for Sugru. What are some others? I have one package left.

I'm curious about this stuff - it might be good for getting rehabbing levers with unobtanium hoods, like Dura Ace 7401. I haven't seen it done, just a couple conversations about potentially doing it on forums. Someone's got to take the plunge and report back!

The stuff hardens in the packets after many moons though.

Other possibilities ...

- Repairing a big nail hole in a tire tread (but not until you get the bike home and let it cure for a day).

- Making "handles" for your $5 park cone wrenches.

- Those black inserts in Dura Ace brake caliper cone nuts. Or maybe the same use with Huret rear derailleurs.

- Custom pedal dust caps.

- Finishing tape for bar tape. wtf? Now i'm really reaching. lol.

Weirdly timely thread. I've been considering getting some of this stuff to do a repair of a divot that was taken out of a black, plastic dust cap on a Suntour Cyclone pedal (I clipped a curb, when I some idiot in a car encroached too close to me). I wonder how hard the stuff gets. I was thinking about putting an overabundance of it in the hole, letting it harden, then filing/sanding it down to fit the original shape.

Sounds like the perfect application. Search "sugru black" on ebay and filter by U.S. sellers. Buy the least expensive item, probably a 3-pack. Use a disposable glove.

I wonder how hard the stuff gets.
It's like rubber, I think.

That would probably work.

I put too much on my Turbo saddle the first time. A couple days later, I filed it down and opened another little condom-like package of the stuff to finish it. I wish i had not used so much the first time. I should have rolled out a long piece for the whole back of the saddle, and then worked that in. I would not have needed to open another package.

Yeah I have stored it in the fridge but it probably has expired...that's a frequent problem the (segue alert) the OTHER favorite gook I go-to all the time and maybe even more practical for some of the same repair opportunities that folks might try Sugru on: Epoxy Putty. If you buy the (smallish) tootsie roll at big boxer shops you'll probably only find it in battleship gray in the plumbing aisle or a tan color for wood, but if you look deeper you can find it sold by Mohawk for woodcrafters in a longer tube in black, white and dozens of wood-species-match colors like "walnut" "mahogany" "maple", plus you can blend colors together when you knead them. The putty sets up (I'm guessing) much harder than Sugru because when hard you can drill, tap and sand it but before it cures you can do a lot of shaping and smoothing with rubbing alcohol. But there's a limited time-window, the Mohawk in particular "kicks" pretty rapidly, maybe 20 minutes until hard, but I leave ALL epoxies 24 hours to "fully cure".

Sounds interesting. I used black acrylic caulk on a good sized gash in a leather saddle. Really didnt think it would work but it held up fine. I used caulk for rips in my rubber mat floor covering in my van too. Thats holding up well too.
