So many interesting bikes on this page. I wish I had more patience to really learn about working on bikes but I just do it as a money saver.
That said, I just converted my daughter’s 7 speed dutchie to a single speed because she didn’t like the shifting aspect. I used a Muqzi tensioner with a GearClamp cog dual clamp: https://www.bikeparts.com/BPC385397/gearclamp-single-speed-conversion-kit-for-shimano-sram-freehub
It went fast and the chain is nice and tight. However, I have two questions that are slightly unrelated.
1.) I used a liquid soap rub on the bars to get the grips on and the outside half is sliding around. And better ideas for getting grips on?
2.) The hand breaks for the rear breaks are not springing back into place but when I tighten more the breaks are rubbing on the wheel. Should I be using a tool to tighten the break cable? I’m just pulling with my hand…Thanks ahead of time.
i’ll second barthartley, isopropyl alcohol is the move if you don’t have an air compressor
what kind of brakes? try testing them without the cable, like just in your hand. if they’re caliper it would be easy to tell if the spring is bad. if they’re canti/v remove the cable and test how the arms move on the boss, if they don’t spring independently then the spring is probably the issue. also if you work on brakes with any frequency, or even if you don’t, a fourth hand tool is a must for getting brakes tuned.
I don’t have an air compressor but I certainly have rubbing alcohol (91% IPA). I can take the grips off, wash the soap off and dry and then rein the bars with IPA. Thanks.
Thanks for the break information. I have always worked on my bikes since I was 12 and my attitude with breaks is, good enough. However, being that this is my daughter’s bike she will be using to commute to work I am more concerned about issues.
This may shock you but I didn’t know hand brakes have grips. I thought the system ran on tension only, good to know.
This is the bike BTW…

I’ve worked on those before and they’re notorious for bad rear brake adjustments due to the cable routing. Often times the cable or housing gets kinked from the factory which causes a ton of drag.
Thanks again. Watched a few brake related videos tonight and after learning more about how brakes work I fixed the issues as best as I could and came to the realization that the brake levers on this bike are total garbage. On my bike I have entry level Tekras and they are so much better. There were three issues, two of which I fixed.
1.) The noodle slipped further down the cable then it should have. I slid the cable cover and noodle up to reduce cable slack.
2.) the barrel tighteners are garbage. They seem to be stripped. I played around as best I could but they don’t seem to tighten the levers at all.
3.) Way too much cable. If I was going to shorten the cables I would buy a whole new system but the brakes work fine now so I think she can manage.
The grips are only wiggling at the last inch so seems like the excess soap migrated to themselves of the bars. Not going to uninstall the grips for such a small amount of movement.
All and all the single speed conversion is done. I would share a picture but it’s not really a bike that I am very interested in. Just a bike for a 15 year old girl to ride across town to work.
Thanks all…
