[Closed] Adding a stealth-routing hole - good idea?

I've done it one 2 bikes and I've not died yet.

I guess it depends if you're worried about warranty or not.

My - erm - friend is contemplating it on second hand frame, so out of warranty.

So no - he's more concerned about dying horribly in a freak broken seat tube incident.

I'd ask the company tbh- I did it on my Hemlock, Cy did some engineering sorcery and went basically "It's [i]probably[/i] fine. Do it as close to the BB as you can, make the whole as small and even as you can, and don't come running to me if you die". Worked out fine.

(If I was doing it again, I'd do it offset to one side though- I centred it and it was a pain in the arse to drill and tidy. You want an angled hole really, or oval, because the hose doesn't go through at right angles.)

Did it on a cheap carbon frame with no problems for the few months I continued to use it. I cut a slot by drilling two holes close together and made sure it was filed smooth.

If it is going to worry you just go non stealth, I have a more 'it will be fine' attitude to it.

That's how I did my Enduro, spotted some of the team bikes were like that so asked one of the mechanics the best way to do it.

My latest one I've copied how they're done on their other similar frames and gone in through the head tube. Possibly more chance of death... maybe. I'll let you know!

I guess alot depends on how you ride.

Will it weaken the frame, almost certainly.

Do you ride the bike hard enough for that weakness to be an issue to the point it causes it to fail? Only you know that but I suspect short of crashing most of us dont put enough force and stress into the frame to cause it to fail even if the hole has weakened the frame.

I'd ask the company tbh

Yeah - probably best thing to do!

Will it weaken the frame, almost certainly.

I figured it would, but then all frames have small blow holes / bottle bosses etc., so it's more gauging how much it will weaken it. I know Litespeed advised on areas to route a stealth house on their older frames, in relation to heat treated and butted areas.

Pretty much my thinking. 🙂

I did it to my bandit. Same place as the later models.

A slot is better for routing than a hole. Drill two small pilots, then make them larger. 6mm from memory and then file the gap in between.

Not wanting to pee on the bonfire, but we had a decent quality commuter bike in the workshop, only a couple of years old, with a crack right the way round the seat-tube from one side of the (manufacturer drilled) hole for the mudguard eyelet to the other. Not saying it'll happen every time, just to be aware that it's a possibility.

What about doing this on a steel frame, from a rust point of view? I know frames aren't watertight, but being so close to the filth...?

I think it was [url= http://syntace.my1.cc/liteville/pdf/RockShox_Reverb_Stealth_an_Liteville_engl.pdf ]Liteville [/url], not Litespeed

Drill a small hole under the bb to let out all the water that'll flood in too

I think Turner gave it the time up on the burner. I've seen a few pictures, looks tidy.
KS lev is so good though, I probably wouldn't bother with a stealth.

I asked Brant,he said it's built like a tank but don't quote me on it.So I drilled my Codeine whilst it was still in the wrapper.
I did'nt die.
The person I sold it to did'nt die (probably,but I've not seen him lately).
YMMV

I think it was Liteville , not Litespeed

Yes - you're right. My mistake. 🙂

As above is it really any different to water bottle holes?

Yes and no. They tend to be a little larger and a bottle hole usually has some support from a bolt*.

*Well, that's my layman understanding of it.

The frame is designed to have those, so yes.

make the whole

Interesting.

Drilled out one of bottle cage bolts and it took a cable fine. Aluminium Scale it is so the bolt for the cage was a kind of threaded rivet.

I did it on my previous bike a Lapierre Spicy by copying the location of the model from the following year.

Worked out fine.

Can't get a drill in to where i want on my latest bike Saracen ariel or i would do this mod to it too.

Friend of mine did by just removing one of the bottle bolt inserts and using the hole left behind.

I'll probably do it to my Alline 160 if I need to replace my Reverb in the near future
