Carlperkins Posted May 8, 2011 Report Share Posted May 8, 2011 thinking of running my cables through my frame and grinding off the cable guides etc. is drilling 2 holes in the frame a good idea? will it effect the strength of the frame?

PaRtZ Posted May 8, 2011 Report Share Posted May 8, 2011 Well, if youre talking about drilling holes in any of the tubes, yeah of course it will affect the strength! I assume you want to know if you do it, will it break a lot quicker than normal but thats usually pretty difficult to perform stress analysis in these circumstances. Its been done before and continues to be done, but for the sake of 'looking better' sacrificing frame strength and the life of the frame is not worth it. Whats your reasoning for wanting to run the cables through your frame? Please dont say that your grinding off the cable guides to save weight....

Matthew_Gibson Posted May 8, 2011 Report Share Posted May 8, 2011 Onza are filled with holes from new! I dont use them, cant bleed a brake for shit on the bike, has do be on a bench for some reason, only reason I dnt use mine! Quote Link to comment Share on other sites More sharing options...
dirt jumper jake Posted May 8, 2011 Report Share Posted May 8, 2011 Dont. Unless you can drill a perfectly round hole, it will crack. Quote Link to comment Share on other sites More sharing options...
Sam T Posted May 8, 2011 Report Share Posted May 8, 2011 Will effect your warrenty aswell. Quote Link to comment Share on other sites More sharing options...
Carlperkins Posted May 8, 2011 Author Report Share Posted May 8, 2011 its not a new frame. just wanted to do it to make the frame look cleaner. now it seems like not such a fresh idea haha. Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted May 8, 2011 Report Share Posted May 8, 2011 I think it'll be fine, dont drill on a gusset or weld. Try and use a pillar drill or a some sort where you know it wont slip and clamp the frame solidly. Quote Link to comment Share on other sites More sharing options...
wip-bikes Posted May 8, 2011 Report Share Posted May 8, 2011 It will certainly weaken your frame unless you braze/weld on an internal boss or reinforcing ring depending on the material. I run them internally but i make the tubes suitable. If your not too bothered about the frame, hay give it a whirl they do look cool.

Carlperkins Posted May 8, 2011 Author Report Share Posted May 8, 2011 hmm.. well the last thing i want is to drop off and lose my face due to a snapped frame. i think ill just leave it for now, it would look mint cosmetically but probably not worth it.

wip-bikes Posted May 8, 2011 Report Share Posted May 8, 2011 (edited) Well if you do try it, just make a good job of the holes Edited May 8, 2011 by wip-bikes Quote Link to comment Share on other sites More sharing options...
P1NKY Posted May 8, 2011 Report Share Posted May 8, 2011 u can do it as adam from tarty bikes has on his 20" and looks proper sexy, and strength? depends were u drill if you copy adams idea u can make it look sexy and not compromise frame strenth Quote Link to comment Share on other sites More sharing options...
Carlperkins Posted May 8, 2011 Author Report Share Posted May 8, 2011 i got an '09 neon bow, im basically just doing a little project mod, making it sleek and light for some fun. id prefer to run cables internal and have a completely sleek frame. ill look at adams thread tomorrow, maybe PM him and see what he thinks. i dont want to build the bike up, make it nice and then twang it in half haha.

Rich Pearson Posted May 8, 2011 Report Share Posted May 8, 2011 its not a new frame. just wanted to do it to make the frame look cleaner. now it seems like not such a fresh idea haha. Thought about trying superglue? I know what you mean about trying to make the frame look tidier, especially when I got my new Zhi and hated the look of zipties all down my top tube, soooooo -> My bike. Just ziptie it in place (you'll need about ten zipties) and carefully apply a layer or two of superglue. I've tidied mine up since those pics and removed all the white residue. Just looks generally really tidy. Should save you having to go drilling anything Rich Quote Link to comment Share on other sites More sharing options...
Bigman Posted May 8, 2011 Report Share Posted May 8, 2011 I did this to a CZAR frame that I had, I made sure that the hole at the top of the headtube was inside the gusset so there was extra strength there, as for the other end, I just positioned it where the cable would line up for the rear brake. When the frame died it did not die where it was drilled! Adam Quote Link to comment Share on other sites More sharing options...
Carlperkins Posted May 8, 2011 Author Report Share Posted May 8, 2011 so you mean like this.. under the red bits are two holes in the support im guessing you mean go through one of them? then out the arse end somewhere. this is an example, i dont have that frame.

Endohopper Posted May 9, 2011 Report Share Posted May 9, 2011 I've done this to 2 frames now without ill effect , but balked at trying it on the carbon top tube of my Koxx for obvious reasons ! I guess this differs per frame , my Base TA26 has pretty solid tube thickness ( yay , cheap Taiwanese frames ! )and the end result is pretty neat lookin'. As said , just ensure that the holes have smooth edges and are at carefully chosen sites , I actually did mine coming in / emerging at an angle to suit the natural curvature of the cable . Note : brake cable , not hydraulic hose - I can imagine pretty serious complications with fittin' olives . Have fun actually fishing the damned thing out of tube at the far end ! Protip : surgical forceps and patience . Quote Link to comment Share on other sites More sharing options...
Bigman Posted May 9, 2011 Report Share Posted May 9, 2011 You can see here where the hose went into the frame, unfortunately I do not have a picture of where it came out, but it was on the side inline with the slave. Adam Quote Link to comment Share on other sites More sharing options...
Carlperkins Posted May 9, 2011 Author Report Share Posted May 9, 2011 yeah ill be running brake cables most likely, gonna go for dual BB7's, cant afford hopes. i think ill strip the frame and then have a look for a suitable place to drill. for the rear end i will probably run the cable out of the end of the tube. like. if you imagine and onza t-pro.. there is an "onza" logo on the end of the tube, just infront of the rear tyre. i imagine drilling a hole in that wouldn't have any effect on strength.

Ash-Kennard Posted May 9, 2011 Report Share Posted May 9, 2011 just take the brakes off Quote Link to comment Share on other sites More sharing options...
Matt Burrows Posted May 9, 2011 Report Share Posted May 9, 2011 It depends on the frame really. It certainly hasn't effected the strength of mine, but then my top tube is thicker than most frames downtubes Quote Link to comment Share on other sites More sharing options...
RossMcd Posted May 10, 2011 Report Share Posted May 10, 2011 I have done it on two bikes. I done it on an onza t-pro and a 07 zoo python. didnt affect the strength one bit. So just do it On the neon bow let the cable come out from the end of the tubing. Thus it will be easier to get it out the other end. and it wont weaken it either.
