This is a super secure way to mount a mirror, lights etc to your Omnium. I'm using any star-nut and a PNW mirror. The hardware from the mirror is the same thread pitch as the star nut.

I could see this being really handy to mounting different things. Just don't do it on the front if you ever want to use your extender bar again.

Hey everyone,

At first I wanted to put a motor on my Omnium, but I eventually changed my mind. Instead, I decided to make it lighter and customize it a bit more to my taste.

The idea is to give myself some motivation to lose weight, get back in shape, and actually enjoy going out riding again.

I ride a stock Omnium Cargo V3 with the dropper seatpost and dynamo hub, which makes the bike relatively heavy.

So I started removing things I didn’t really need anymore. First was the child seat mount, now that my son is old enough, i also remove the tenders. Then I swapped the dropper post for a Thomson seatpost.
I didn’t really save weight there, but I also changed the saddle for a Brompton Swallow. I had an old TUNE handlebar lying around, so I installed it, and a cheap second hand TUNE stem should arrive soon.

I also changed the tires to a GravelKing SS+ 45mm in the rear and a Panaracer HP406 up front.

Honestly, the bike already feels completely different.
I didn’t realize how stiff a carbon bar could feel.

There are still a few things left to do, like finding a lighter crankset. After that, maybe it’ll be time to think about changing the wheel rims… or maybe even the whole wheelset.

If you guys have any ideas to make the bike lighter without spending thousands, I’m all ears.

Especially when it comes to the wheels.

(And yes, I know… the green grips have to go.)

I made a ittle holster for my kryptonite lock.

A small bag but a big improvement.

I had upgraded from a stock crank set and an unreliable square taper to hollowtech II.

My previous cranks had a habit of loosening on NDS, so I decided to go to hollowtech and 34t ring.

My setup is 12 speed Shimano SLX, non boost version, matching Shimano BB and Zrace chainring.

First I couldn't remove the crank on the drive side, using a crank puller, the threads got stripped, so we had to use a bearing puller, that gave us enough space to use a little flat screwdriver and hammer to undo the old BB.

Then we found out that V3 Minimax BB shell is not MTB spec, so we had to use 2 shims under BB shells to fit it with cranks.

Shimano gave me the wrong plastic nut for NDS tightening, but lucky me I got hold of one that had longer threads.

And because I had a small brain day, I overtightened it and now I can't undo that, so my cranks are stiff. But hey at least I can ride.

So yeah, use road standard things I guess....

I bought a used Omnium from 2023, seems to be one of the last V2 Wifi without the V3 dropouts.

Today I switched the installed Mudguars because they have been damaged by the previous owner.

On the front wheel I recognized that the mudguard is quiete squeezed in the fork. That much that it damaged the paintjob and a little bit of rust evolved (eventually more from the guards than from the frame).

The new "official" V3 mudguards are more on the plastic side, but they are also quiete jammed in there. Is this normal? I tryed to fix the framedamage with some paint and think about applying some protective adhesive.

55mm tires fit, even with some room. I think Wifi is confirmed.
