Bora One Maintenance and/or Upgrade

[skidrrr]

Just one year on our far from perfect roads and my rear wheel hub has a slight but noticibile vibration. It is time to maintanance I guess.
1. I'm wonderng what is the best grease to use for campy USB hubs?
2. If bearing needs to be replaces can I use hb-hy100 kit and not hb-sh100 to replace and upgrade my one to ultra?

Judging by sceme in the catalog hub internals look the same

You can use any bicycle grease for the USB hubs. To convert 'ONE' to 'ULTRA' you need both the HB-BO100 and HB-HY100 kits. The HB-HY100 kit should read 2xE, 2xF, 2xG, and 2xH. You will also need to buy the Campy race extractor kit to remove 'B' from the front hubs and 'G' from the rear hubs, as well as a race press tool. I don't know the part numbers from someone on WW has done it and described it in the Bora WTO thread.

Campagnolo uses Kübler Isoflex Topas NB 52 - white barium based synthetic grease. (Also sold by Campagnolo rebranded as “Campagnolo Professional Grease”). NB52 is a very good premium lubricant made for rolling and plane bearings and also water resistant and long lasting.

Thank you Priit and pdlpsher1
I'm definitely going to buy Campagnolo Professional Grease and will think about upgrading bearings to CULT

For now I just re-greased it with what my friend suggested and borrowed to me.
It is a toxic green shimano premium grease


Interestingly drivetrain side bearing was noticeable dirty while left one was quite clean



I still can feel slight vibration when I roll the wheel in my hand but it is better an I'm ok with that

Side note, what size GP5000 are you running on that wheel and how do you find it?

For better aero I used 23c. Even thouh I did only 2rides so far I find GP5000 quite insipring and way more fun to ride than GP4000SII.
Comparation with s-works turbo cotton is a different story. I can't decide yet what sensation I like better. Turbos are softer but GP5000 seem to accelerate faster.

The Shimano green grease is a very good grease. It's tacky and repels water quite well. It's common to see the drive-train side being more dirty than the NDS but your DS is super dirty. I'm glad you took care of the dirty bearings.

I'm running GP5K 28's on my Bora 50 Ones and Bora 35 Ultras. Love the comfort and handling of the wider tires.

Are they the newer, wider, Bora's? If so, have you taken vernier calipers to the GP5k28's and measured how wide they inflate?

How often should the maintenance (cleaning & greasing) be performed for CULT bearings?
Campagnolo says on their website: "they must be cleaned and lubricated with synthetic oil according to the periodic maintenance table." but don't provide a "maintenance table".
My mechanic is saying every 1000km

PS: Campagnolo recommends synthetic oil, not grease for CULT bearings : https://www.campagnolo.com/WW/en/Suppor ... e_bearings

Every 1.000km? That's 2 weeks of riding for me in the summer.

I'd probably say every 7.000-10.000km, but summers here are pretty dry the last years (who'd thought a Dutch person would ever say that?) and roads are generally really good.

Water = killing. That's for sure.

These are the newer ( AC3 ) ones. You can tell by the brake track.

@skidrr - Is the vibration also without the tire... in other words : Tires can cause vibration also.
