If I'm going to replace them I will need to get the right ones and unfortunately if the info is in the service manual I didn't see it and I'm at work now so not in position to check. And just in case I can't work out timing with @texasnurse this morning I may go ahead and order from Amazon...but before I do that I need confidence I'm ordering the right size.



Looking at Bikemaster I see they have 10mm and 15mm rubber valve stems. Interestingly they have two different 10MM stems, the TR412 and TR413, but I don't see any explanation of the difference between the two on their site. As well, their 15mm stem is also labels TR412. I am confused...LOL!!



Finding a stem puller isn't nearly so complicated but if I'm going to the route of replacing the entire valve stem I damn well need the right one.



Who knows the answer?


Tr412 is the factory stem

Cool...I'd probably go with something like that if I didn't already have 90 degree attachments. But very good for those that haven't done gone to 90 degrees yet...makes it MUCH easier to check your pressure and add PSI.

Question I have is that while the product description says "10mm" all of the other references say "11.3mm" which leaves me wondering if 10mm stems would be the right choice or if I need to search for 11.3mm now.

@KeepRidin - Am I correct then that these unscrew for install and you screw the base back on once it's threaded through the hole in the rim? As opposed to the rubber stems that get pulled through the hole in order to seat in the opening.

As I think about it while typing this, since my son just got a used starter bike I could replace my stems with something these and just give my 90 degree extensions to him. Please let me know about these aluminum stems and how they're installed.

I'm trying to decide what to do and communicate with @texasnurse in time to make a decision today and order/ship what I need today so I can knock this out in time to get some riding done this weekend.

Thanks,
Chris

@ChrisHead You are correct on install. I put a dab of locktite on the threads just to be safe. I was worried about leaks around the stem at first but 6 months later I haven't had to add a single PSI, so I think we're good. There is enough space inside the wheel to get a socket on the nut, and I used a decent set of channel locks with a rag to hold the stem side.

I wish I would've measured these before install as the product description is very confusing, I just hoped for the best and was glad it worked, lol.

I wonder if those angle valves mess with your wheel balance? I am sure the wheels would have to be balanced once they are installed. So far I haven't had any major issues checking my tire pressure or putting some air in with the regular valves installed.

Both tires I mounted with these 90 stems needed weights opposite the stem (no surprise really) but didn't need more the the factory tolerance stated in the service manual.

And another advantage of balancing beads. . I put them on all my scooters. Now if I just remembered to have them facing right so I could reach them easier,
the ceramic beads ( or Ride On ) makes it a plug and play event.

That which does not kill me tends to really piss me off.

With Ride On there's no need to plug. And the ceramic beads have not interfered when I used a plug. .
