Advice on bolts.

[PedalUma]

The 3 spd + 350w bb interests me, I´ve been looking for something that suits my ´vega mixte.
The stays & fork are too narrow for hub drive, but that setup might be ideal. The ´Vega is
race built with Tange pro tubing. The frame set weighs just 3 1/2 pds. There are carbon frames
that aren´t as light. Kit specifics?

Your classic mixte will outlive a new carbon frameset. They become brittle and cannot take a ding. And I am attracted to the fact that you are taking imbedded carbon and pushing it out, instead of mining, manufacturing, and shipping something 100% new. I love the ride qualities of old high quality steel frames. They make some of the best electric bikes. Tange! Cool. I bolted on a TSDZ2 to those three-speeds. Here is an old Centurion in the process. The motor got painted in a brushed aluminum color. I just tested it. All is well. It just needs the pedals and chain. You can see the connector to the battery by the black water bottle cage on the down tube. The new chain is currently in the ultrasonic parts cleaner to remove the sicky shipping grease. Then the chain will be treated with nano-ceramic lube after lunch.

They are color specific to the dropout angle.
John, That was a kilt guard I removed. You need to be 1.9M+ to ride it.

WOW!!! I had spent HOURS searching for these a few years back, actually in 2014. Wanted to use a SA 3spd with drum brake but couldn't find the right adapter.

I found a centurion frame in a ditch by the road,frame,fork,& bb, nothing else. Built it back. Stripped it down
to the original paint & road it for 2 yrs. ´til It put me in hospital. It was cursed. Stripped & put it back where
I found it. Love the mixte, the frame flexes ever so slightly in turns; It carves turns like a good pair of skis.
Took it home 1/2 hr, after it posted on CL, (girls bike $60) Seller hadn´t a clue what it was. I put 10k onto
it before going electric.

Not true! Use Blue! No heat but a good hold.

Other than not working, a product. With loktite blue on the rear axle, I had to remove 60 lb groceries, take the panniers off, turn the bike upside down out on the road, move the axle back and re-tighten. Worthless. Lots of fans of this useless ****. Poster that thinks torqueing to the limit fixes the axle in place must never have ridden a bike more than 1000 miles. What really works is screws built into the frame that push back on the axle. Not seen on any bike after my Mother's 1947 Firestone. Next best is double nuts counter-torqued.

@john peck, Hardcore road bike racers like to feel it in their bones and fillings. Their bikes have a short wheelbase so they are twitchy. Riding a Mixte for them is 'Riding a wet noodle.' I also like how a Mixte has a long, stable wheel base and with a classic steel frame absorb road chatter and flex and carve like skis. You don't feel wave chop on a log yacht. This one is 48V, 750W. Check out the chain. This was from over two-years-ago, before my builds started getting cleaner.

You can tell a race mixte from others, the have a more vertical seat tube, Yeah, they´re twitchy alright.
Kinda like the difference twixt a Fokker tri-wing & an F. albatross. It´s agile, but it can hurt you if your
foot is forward on the side you turn away from. What chain is that? What bike, can´t see the badge?

Next best is double nuts counter-torqued.

Or use chainring bolts if its a horizontal dropout, which is what uses those dropout set screws. i have them on both my Chumba and Lynskey frames, as well as my Motobecane Lurch. For the first two, the set screws affix the entire dropout which is vertical so this kind of slippage does not happen.

But for where it does, a chainring bolt will slot directly into the dropout as a perfect fit, with the bolt flanges on either side acting as retainers. Then bolt the wheel on using proper torque spec vs. praying that overdoing the torque will work (as noted it won't).

The bolt shown in the pic is a Wolftooth alloy bolt meant for a single chainring (i.e. short depth). Truvativ steel bolts work equally well and are much cheaper. In this case look closely I used a steel inner to beef it up. But there's no real need as the load on the bolt is miniscule. As you can see you could even stack two of them in this particular dropout if you were doing something nuts like using a super tall Snowshoe 2XL. Between this and a chain tensioner I eliminated all BS associated with singlespeed setups, slippage and chain tensioning.

John,
Good eye! The bike is a Kimpton Red M7i from Public Bikes. The chain is a KMC City Hunter.

I ditched the white housings and white tires and used extra-strong brakes. I also used black grips and saddle. The brake inserts match the frame. I like the painted rims. I purchased it new from the manufacture as a blem. It had a nick in the paint which I repaired. These bikes were designed to be used at hotels and resorts as day rentals. Because they are low step, anyone can ride one. The IGH makes it low maint for a rental bike.

My pleasure to be useful. Here is an electric bike I made that is going out today. And my go to daily rider with the Union Jack. Both are Nexus three-speeds with 350W mid-drives.

That looks rather nice to my Jaundiced eye
