Deuter Bike One 20L pack here.
Great pack, have used it a number of years (since September '14) so had my moneys worth (cost me £65!). Multiple useful pockets, good straps, good features. Solid and dependable. No damage/wear other than fade and a couple of tears on the 'rain cover' (which I have on all the time as it's high-viz). My only 'gripe' would be the rear being kept flat by a piece of foam which has.had no strength, so the 'air contours' on the rear to keep it away from my back only half work. Taking it out the pack goes all floppy so would have to swap it for something firm and cut to size. Doesn't bother me too much as I'm not riding more than 20-30 mins tops (and any pack is going to give me a sweaty back to some degree)...
You were sucking your thumb when I went tubeless on my other bikes
Ouch, burned haha! I'm probably not as young as you think!
What reservations do you have? I can only speak for myself of course, but the only road tubeless issues I've had were in the initial setup and totally my fault!
Pretty much the same experience as me (so far)... Have not even bought any worms yet and probably should...!
Lunchtime viewing from Hambini - BB removal and checking on a Tifosi carbon frame

BB alignment on the frame is a dogs dinner - he states that the life of the BB would be reduced by 75%!
Thanks. Really like his write-ups but its been a few weeks since I caught up. Does he do much on YT?
We're sure he can be trusted to be unbiased aren't we? He certainly seems quite honest in what he's demonstrated and the GCN video I saw of him he was very instructive (about bearings and how they're sized and labelled I think?), without being too cycling specific. Well worth a look if you can find it.

Carbon is hard to make precise, at the cost of a bike frame at least.
I'm all for fully machined metal inserts bonded into the frame which means bearings line up.
Yup totally agree. Metal is much easier to machine very precisely, but then you've still gotta have that insert correctly aligned in the frame. If that's a manual 'build' process of layering carbon in a mould holding the insert in place then it's never going to be perfect in a 'handbuilt' type frame. Then again it's the misalignment of the two sides of the BB which is the problem, the whole insert being slightly out isn't a huge issue, providing there's not two sides of it which are then out of alignment. Those with machines laying/building/injecting carbon frames really should have no excuse!
The pain I had identifying my Specialized sizing 'type' in the frame to identify the correct BB I imagine is only part of the battle bike shops encounter (other brands have that information readily available). Thankfully for me mine had a machined metal insert in the frame (great) but there did appear to be one each side with a gap between them... Obviously I'm unable to see if there's additional supports between them keeping them aligned. I sure hope so! If there isn't, then they solve nothing with any bearing alignment!
My Wheelsmfg BB30-OUT pushed straight in the DS. Bit tight. There's a rubber O ring around the BB and that really was tight, but was able to push it in by hand. Would've pressed/rubber malleted it in if any tighter (and the little man wasn't in bed almost above me). NDS screwed in perfectly, again quite tight.
'Tighten to 35-50nM'. My torque doesn't go that high and
I got the spanner not
the socket/adaptor anyway, so that was man tight + 3 grunts.
The Praxis M30 BB it replaced had a collet type system, where the DS pressed into the frame (around as tight as the Wheelsmfg but no rubber O ring), then the NDS screwed in expanding the BB to grip the insert. It bottomed out, so relied on sizing rather than relying on torque to hold it in place. It worked quite well, but with a slight gap there muck/dirt/water would get in there. I think it then sat there and worked its way between the insert and BB, eventually causing a bit of a creak and groan. Quite easy to take apart and clean out (bought the £20 Praxis tool for removing the BB). Got quite bored of doing it every 3-4 months and tried various ways to stop the ingress to little avail. The soft alloy of the bearing covers made sealing the bearings a PITA and mine eventually got damaged with all the removal & refitting making things worse. The rubber covers on the Wheelsmfg should cope better than those alloy, along with the torque/0 oring of the BB fitting keeping water/dirt/grit out of the interface. That's my hope anyway. Also going for standard bearings so no 'mare' changing them.
