Hello,

Can I use stick on cable guide for the rear and front derailleur? I'm missing cable guides for my single speed to 7 speed conversion. I already have a bottom bracket shell cable guide.

As a guide for cable in housing, you should have no issues.
As a cable stop, where housing ends and open cable is exposed- no.

100bikes is correct. If just routing cable housing through a guide tunnel, no issues there as there is no stress on a guide, however if using as a cable housing stop where the cable housing butts up against the stop and the wire itself continues on, that is not going to work as a stick-on piece. Too much stress on the adhesive and it will pop off. Last year I played with this and found that cable stops have to have something more than adhesive to hold it in place. I used JB Weld to hold cable stop to bare metal. It worked for one day and overnight the stop popped off.

I used them, but found that they stopped sticking within a few months. All weather commuting is a good test of equipment performance. Although they don't look elegant, nylon wire ties are effective and reliable. Look for the low profile type as they do look quite a bit better.

Since you need these for shifter cables, I wonder if you really need cable stops. If so, something like this is what you should be looking for:

Agreed, stick on guides will eventually fail. Bolt ons are the way to go. Problem Solvers has em.https://problemsolversbike.com/products

A stick-on guide is unlikely to be strong enough to act as a cable stop. Look for a clamp-type chainstay cable stop:

In my experience stick-on anything tends to not stay stuck on for any length of time, especially with heat and water. Zip-tied or clamped-on will stay put much better.

That sounds like a low budget conversion to me. Those Problem Solvers parts will likely to cost you more than the bike. When I was doing that kind of thing I ran full length cable housings and zip ties.

Can I put the shifter inner cable in a housing for shifter? What I'm talking about is covering up the entire length (shifter to rear and front derailleur) shifter cable with housing designed for shifters. Will it work or the shifter cable requires to be exposed?

No the cables do not need to be exposed. In the long away past, it was normal for the cables to run inside a housing most of the way. Then the exposed stretches were introduced, seemingly to reduce friction and maybe weight. When I compared how cables operated with large portions exposed and the housing all the way, I could not detect any practical friction benefit to the exposed cables. In long term, in my experience, the exposed cable under the bottom bracket solution has been horrible and, over time, I eliminated it from all bikes in my care.

So, it will work?

Yes. You only need a clamp-on stop for the front derailleur. You also need to zip tie the housings so that it does not run loose, but for the trials you only need this one stop. If you start with the rear, even that stop is not needed, as the rear derailleur has one built in.

The only time something billed as "stick on" will hold fast is when you want to take it off.
