The Tester Approves thread (see first post)

I've got spare praxis ones if you want?

Beam me up Scotty!

Beam me up Spotty!

Bit rude.

He is so young tho

Something like Shimano Sora maybe? or get the CX50.

Please remind me of the choice for single ring black steel chainring bolts?

remind me

My new wheels came with Novatec hubs (tester approved so far, all good) that feature 'amigo' brand 6902 sealed bearings. They already feel a bit notchy so I'm thinking some pre-emptive maintenance might be in order.

What's a tester approved 6902 2rs bearing? I seem to recall SKF being tester approved, but have also found FAG bearings for a similar price and Enduro for a bit more. Also found ceramic or semi-ceramic bearings for a bit more.

Any of those others worth considering?

FAG will be fine.

Cheers tester :)

Is there a tester approved rim tape?

rim tape?

What sort of rim tape? I like the Schwalbe blue snap on tapes for tubed clinchers.

Yep, for a clincher rim with spoke holes. Thanks.

Just had a flat caused by some Vittoria tape and had ordered some Schwalbe tape as a replacement but just wanted to check there wasn't a better option I had missed.

Looks pleasing blue.

Titanium bolts (for stem, rotors, chainring) - what are the arguments against them?
(except for the obvious price increase)

Soft, corrosion, stretchier than steel so torque settings might not be the same as the standard bolts, won't save much weight and the places you'll save from won't make much difference anyway.

Get lighter tubes. Eat fewer pies. Be more aero.

And if you want corrosion resistance, you can get stainless steel bolts.

@Emyr @fizzy.bleach - what I suspected. Thanks!

You can, although an A2 or A4 stainless bolt won't be as strong as an 8.8 or 12.9 high tensile steel bolt for the kind of sizes you'll find on a bike.

Will A2/A4 be 'strong enough'?
I have no idea the tolerances the specifying Engineers allow for the bolts used on bikes.

Depends on the size of the bolt, the way it's loaded and the loads put on it. They'll be strong enough for some things, but not for others.

Also, using stainless screws in aluminium threads will make sure it's your expensive aluminium components which corrode rather than your cheap fasteners.

Fasteners are a significant part of the design of an assembly, the designer will have considered multiple factors when selecting the OEM fasteners and if you want to second guess that then you probably need to do the same work yourself

Is there a tester approved tubeless sealant?
Are they all the same?

I think you're the first to ask, but 2 years ago Tester was holding out for decent tubeless road wheels... https://www.lfgss.com/comments/12317364/

I use Schwalbe, on the grounds that it's exactly the same as Stan's but cheaper.
