I remove anodising by dropping item in caustic soda (potassium hydroxide) solution for a few seconds then when bubbles remove item and rinse thoroughly with cold water. Wearing rubber gloves of course.
What did you buy your ebike this week?
- Thread starter Simoto123
- Start date
This week bought Maxxis High Roller 3 Maxxgrip 29 DH tyres which will stay on front all year round. Bought DH because DD seems not to be available yet. Paired with Maxxis DHR2 Maxxgrip 29 DD rears which got cheap from Amazon because spotted a pricing mistake - wanted Maxxterra but couldnt ignore price. Tyres will come off only when worn out, finished with changing tyres twice a year.
Bought four new Presta valves. Why?
Changed four tyres and at same time fitted Fillmore valves. Clogged up several times while injecting Muc-Off tubeless sealant, probably due to Muc-Off sealant particle size.
After fitting Fillmore valves binned old Presta valves. Not changing to another sealant so bye-bye Fillmore, back to Presta. If Presta valves clog up then the cores are easy and cheap to replace, got plenty of them.
No prize for guessing why Muc-Off have developed their own proprietory valves.

I use Continental Revo sealant. It has a tapered nozzle for injecting down the valve. The bottle has to be shaken of course to get all the particles contained in the sludge at the base of the bottle back into suspension. But when you do, they won't even come out of the nozzle! It's not surprising really. If the sealant is supposed to seal 6mm holes in your tube, why would they flow through a 3mm hole in the end of the nozzle?Bought four new Presta valves. Why?

It's not just me either, I got my grandson to try it yesterday. My thought was that if it doesn't work it would be a learning experience for him and if it did work, a learning experience for me! He failed as well.
PS: The only time I got sealant down the valve was when I had failed to shake up the bottle first. The next time I got a puncture the latex just pissed out of the hole without sealing. Inner tube time!
There are pro’s and con’s to those Filmore values. When I purchased my first set I added the syringe, tube and MucOff sealant. What a joke that was. I was only able to inject 10-20ml of sealant through the valve before the valve became clogged with particles. I eventually released a bead and poured 90ml of MucOff sealant directly into the tire.Bought four new Presta valves. Why?

Some sealants have large particles,(MucOff, Bontrager). The permanent spring inside the Filmore valve captures any large, stringy, chunky particles and quickly prevents adding more tire sealant through the valve.
Another effect happens when using conventional presta valves. Over time the air holes clog up and prevent any air from escaping. That’s fine …until you need to change a tire.
Some valve cores will slowly leak air and the sealant will block air from exiting, and eventually prevent air from entering (coliflower effect). This becomes a problem when you need to remove a tire and release the psi to zero.
The Filmore valves have a better seal mechanism. I’ve installed Filmore valves on all the bikes now. As long as I don’t burp or puncture a tire, I rarely need to add psi. Deflating or inflating a tire is easy now …whenever I need to do that.
I use a 5mm ID tube pushed onto the nozzle of a 100ml BD Plastipak syringe, then draw sealant from the sealant bottle into the syringe. The other end of the tube is then pushed over the top of the valve, and the sealant injected into the wheel.I use Continental Revo sealant. It has a tapered nozzle for injecting down the valve.

With a Presta valve with the core removed the sealant always flows freely through the valve body into the wheel.
With a Fillmore valve the clearance around the poppet valve is too small and the sealant quickly clogs up often before even half has been injected through the valve.
Always park our bikes with valves at either 4 or 8 o'clock, only occasionally had Presta valves clog up and if they do simply remove and put in a new one. They're cheap as chips.
Edit: As said elsewhere, Fillmore valves are coming out and being replaced with Presta valves.

Hi
This week I bought my emtb an emtb. Action team was old bike, one55 TM new bike nothing wrong with the action team great bike and does everything well. One55 just does everything better (particularly downhill). No2 son taken over ownership of action team so now I have x2 bikes to maintain.

MOTSUV 32T chainring, to replace the 34T Shimano chainring. 20 times less expensive at AUD$5. There is a thread about them on this forum. The reports are good. I'll report on my experience.
At five bucks, I'll change the chain ring everytime I replace the chain.

Bloke spends £5000 on a bike and then £5 on a chainring 
It is colour matched and like he says for that price you can replace it more often. 
The bike looks great, like something of a fairground
Agreed, I always park my bike in a similar fashion. for the same reasons.
I also remove the Presta valve for filling, but I've stopped trying now because the sealant NEVER goes in. The sealant particles clog the nozzle of the injector.
This is what I use, Muc-Off sealant always goes in no probs. As you can see in the pic, the end of the tube goes over the Presta valve body (with the valve removed of course).
Bloody hell what a load of tosh, bought a syringe of eBay and tubing to go from said syringe to valve ( with valve core removed ) injecting Stans sealant to bead seated rims……..what could be easier……… it’s not rocket science.
This last post wasn’t a reply to your problem with the cranks …….apologies mate.I bought this today hopefully it’ll get those dammed seized crank arm caps off, if it doesn’t work I’ll be getting new crank arms

I liked the T-handle version so I got the 4-way. Mmmmmmm.
The thread on this forum said they were good chain rings, so I bought one. Do you want me to offer the seller more money ?Bloke spends £5000 on a bike and then £5 on a chainring
36t chainring recommendation
Hi All I’m after a 36t chainring, can anyone recommend one & maybe provide a link? Cheers

BTW. the bike was only £2,986. (AUD$5800). Maybe I need to give them more money too ......

Bought a Manitou Mara for mrs.Zeds Orbea Rise, she’s not ridden it this year (since the battery died in December and was slowly replaced through warranty - Orbea being slow not the shop that handled the repair!) and when she did there were complaints about the fox suspension as factory fitted*
I must add that she’d been riding her Ohlins equipped Sworks KenevoSL all year (that we built in January - to replace the unridable broken Orbea) so has gotten herself a taste for less basic dampers…
The Mara is shown for size next to an Ohlins coil that she ran for a short time but clearance concerns meant it’s removal.
I’m a fan of the Mara after having ridden one on my Nukeproof Mega and Trek Rail so suggested it & luckily there was a new one on eBay so couldn’t resist
Have to fit the bloody thing now!

It must be the sealant used then. Does Stans have bits in it?
The Stans sealant seems to be a little thicker … no chunks or bits that I’ve noticed. The MucOff sealant looks and feels like small chopped up wool
pieces along with the fluid. The Bontrager sealant looks to have small particles (blue bits) along with thick fluid.
Certain types of sealant will not pass through the Filmore valve because the bits and chunks get trapped in the internal spring during a syringe injection.
I took a Fillmore valve to pieces to measure it for the below post - there is no spring in it.

Hmmm? I wonder how it’s clogging up then? Smallish passage, internal mechanisms?I took a Fillmore valve to pieces to measure it for the below post - there is no spring in it.

I’ve never had success with injecting some sealants through the Filmore valve. After 10-20ml it clogs up. Now I just pour 80-100ml of sealant directly into the tire (1 bead off).
I really thought it was a spring but I guess the psi keeps the plunger valve closed.
