Chain length

The large chain ring on my Trek Verve three was 46t. I replaced it with a 44t and left the chain in it's original length ( thinking because there was a smaller front sprocket it should'nt matter ). I also missed the master link and broke and reassembled the chain with a chain breaker. Been having some chain slip in the higher gears. This may have been caused by a stiff link i noticed yesterday. That is now fixed so I will test ride today. Luckily we have several full service bike shops and i can get a new Shimano chain if i need to. Since this build is not an MTB i don't need or use some of the low gear cogs and I have wondered if i could use an abreviated rear cassette and improve chain alignment by moving the cogs i do use inward. We shall see......

You may be able to get a chain ring with a 10mm offset to bring in the line. Check the BCD and number of bolts. I put an 11-50 on a bike last week and it couldn't hit 1. Too much cross-chaining. The new narrow/wide 10mm offset ring arrives next Tuesday.

I like my 44t bling ring though i did not need the offset. Probably could have been happy with a 46 or 48t as well. Thank you one and all for the input and advice. Bike is running like a champ! This after noon i epoxy bedded my down tube battery mount and it went well. Used Hornady one-shot case lube for a release agent and it worked great. No play anymore between the mount and the down tube.

That is funny, I used epoxy yesterday to repair an electric Vespa-type scooter. It is that persons only transportation. The HB had been vandalized. The throttle was broken off and that side's control housing broken open. To the left the accessory housing was smashed and hanging. The brake levers are attached to these housings. She rode it with duct tape. I had it repaired in twenty minutes. Replacement parts have not been available since 2012. When she saw it she cried with joy. OMG, How did you do this! She kept getting closer and I kept backing off like there was some emotional attachment. No thanks. I used liquid weld. When fully cured it can be milled and tapped. It sets at eight-minutes.

Very cool! I used jb weld (old redneck standby). Let it stiffen up some before lightly mounting it so it would conform to the shape of the tube. Worked a treat!

I use all kinds of unconventional stuff such as: O-ring lube, DOT 5, Horse shampoo, Glycerin, Acetone, Nail polish, Gasket sealant, Heavy aluminum tape, Aluminum anti-seize & Machine gun oil. Try mixing some DOT 5 with Dawn and water in a spray bottle. Shake and mist on old rubber. When it turns white in three minutes, rinse with a light spray of water. This fully restores oxidized rubber and plastics. You will be floored. I feel like an Alchemist sometimes.

Makes sense.! When I have a freewheel that will not come off I first use acetone. As that evaporates it sucks in an application of gun oil. ATF is weird stuff. It has stick and slip qualities. A tranny must slip but also catch smoothly transitioning. One guy said that there is nothing as smooth as a lubed tranny. As for transitioning, I'm not so sure.
