Cycles In Motion 650b Randonneur

this prompt the decision to upgrade it to full Campagnolo Super Record especially with the bigger saddle/bar drop.

This seems like a non-sequitur. Can you expand on this?

Fit a little more aggressive, closer to my road bike than tourer.

I seeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee.

+1 on less gears. But why not go 135mm and be able to make a symmetrically-tensioned wheel (if you use an offset drilled rim)?

Fork looks good. What's the light on the seat tube?

Integrated dynamo rear light, the wiring go inside of the frames, made by Compass.

I got a 13-24t cassette for it (removing the 11t to make it into a 6 speed).

I edited^^ to ask: why not go 135mm and have a nearly symmetrical or actually symmetrical wheel?

I love the fork and like the build in general but please throw that particular rear light into the bin. What paint are you going for?

135mm? is there's a 6 speed freehubs that is avaliable in 135mm let alone 130mm?

Also, having a wide hubs mean that the chain line will not be very even, a 120mm hubs mean that the chainset can actually be moved closer to the bottom bracket than typically.

Lastly, I also have a 650b with 130mm hubs, I used to ride it with 6 speed plus a couple of spacers, but it's not exactly a solution, in the end, I put Dura Ace 10spd on that 650b so the Cycle in Motions will have 12 speed with friction shift.

Here's the hubs I'm going to use, it's the middle one with a much shorter freehub body (compare to the last one with the normal 8-10 speed one).

With shorter freehubs body, less dishing is needed.

Aha yeah chainline, of course.

Though if you could switch those^ axles over you could have a 130 or 135 with a the short carrier body and less dishing. What hubs are they?

Hope Trails will take 6 8s sprockets. Admittedly you have a redundant disc mount but they are super loud. Does fuck with your chainline as you mention.

The chainline is the thing, I see.

You might know this already if you've got the parts, but from my expirience with the same hub (SunXCD 120mm), using a 7 speed cassette with one cog removed, it's better to take off some other one than the smallest. As the smallest has the spacer built into the cog itself, and the others are just made of plate with separate spacers, if the outermost cog is not one ment to be that, it's splines will sit at the edge and partly over the edge, on the freehub body, as the splines on that don't continue that far. So it will work, but it's more likely to mutilate the freehub, and you can avoid this by taking any other instead.

The project is really interesting, subscribed.

Not to contemporary need or popularity, but really interesting build. Digging the 6 speed choice. What will you be balancing the gearing up front with?

46/30 chainset, with a spare 48/32 for flatter route.

30/24 give a similar gearing to 34/28, and 46/13 are plentiful, I don't intend to descent as quickly as possible, just to climb well enough.

Also have a 14-28 cassette for more range, I have been ridden with 14-28 for years and was more than enough for everything.

@Samuli I have taken this in consideration, I intend to removed the cog from the carrier and fit custom spacers, the alu freehubs body does get chewed up but as long it's greased, lockring torqued and sufficient space, it will be fine, thank for mentioning this tho.

Remember how awesome your old friction shift 5/6 speed bicycle feel? That's why.

Also the chain line mean chain last significantly longer due to less cross chaining even on the extreme big/big.

I have a Dura Ace 7400 derailleur to be fitted soon, a modern derailleur doesn't really work because the screw limiter doesn't stop it from going over the cassette!

Should I rename this topic to 11 speed are dead?

I fucking love this project, cantis get me excited .. always. cc/ @snottyotter

and yes

Techincally, it's a 12 speed bicycle!
