Hi everyone,

I’d like to confirm the compatibility of the Magene P515 powermeter crankset with my current bike setup and make sure I have all necessary tools and components before starting the installation.
I've never installed a powermeter or changed my crankset before, so I want to be sure that everything is compatible before I order it.

My current bike setup:
   •   Bike: Canyon Endurace CF SL 8.0 Disc (https://www.canyon.com/en-de/endurace-cf-sl-disc-8.0/2185.html?dwvar_2185_pv_rahmenfarbe=BK%2FGY&dwvar_2185_pv_rahmengroesse=S&history=1)
   •   Groupset: Shimano Ultegra R8000 (50/34 chainrings)
   •   Bottom bracket: Shimano Pressfit BB72 (PF86.5)
   •   Crankset: Shimano FC-R8000 (Hollowtech II (24 mm spindle)) (https://bike.shimano.com/en-NA/products/components/pdp.P-FC-R8000.html)

Magene PES 515 Info I've found:
   •   Comes with PES20 crank arms (24 mm steel spindle)
   •   Uses standard 110 mm 4-bolt BCD
   •   Magene offers its own QED chainrings, but I’d prefer to reuse my existing Ultegra R8000 chainrings if possible.

My main questions:
   1.   Is the Magene P515 crankset fully compatible with my bike (PF86.5 BB72, Ultegra R8000, 24 mm spindle)?
   2.   Can I reuse my existing Ultegra R8000 chainrings, or do I need to buy Magene’s QED chainrings due to BCD differences (as Shimano’s 110 BCD is asymmetrical (ChatGPT said that they are not compatible))?
   3.   Do I need to replace the bottom bracket, or can I use the existing one (it’s running smoothly)?
   4.   Did I forget any essential tools or parts?

Tools I already own:
   •   Allen keys
   •   Torque wrench (up to 25 Nm)

Tools I think I still need to buy:
   •   Shimano TL-FC16 (for the preload cap)
   •   Chainring nut wrench (for removing/reinstalling chainrings)
   •   Threadlocker (Loctite 243) or grease for chainring bolts

I’m not planning to remove or replace the bottom bracket, so I assume I don’t need tools like the Park Tool BBT-9 (for threaded BBs) or press-fit tools.
Any confirmation or corrections would be much appreciated. Thanks!

• It should be compatible with your bottom bracket and R8000 chainrings.
• You don't need a chainring nut wrench for the Shimano bolts because the nuts are built in to the large chainring.
• You will actually need a 44mm 16 notch bottom bracket wrench like the Park Tool BBT-9 but you'll use it for the Magene spider lock ring. Also, get the wrench style and not a socket/cup style because it has to fit over the spindle. Torque spec is 35-40 Nm but you may have to just guess if your wrench doesn't have a 3/8" square drive hole for a torque wrench.

Hey everyone,

I’m currently putting together a rain setup for bikepacking and would love some input from folks here. I’m mainly looking for lightweight options that pack down small, since space is quite limited.

1. Rain Jacket
What’s your go-to compact rain jacket? I’d like something that fits easily into a jersey pocket or saddlebag but still holds up in sustained rain. It should also have a hood which goes over the helmet. Bonus points if it doesn’t turn into a sauna after 10 minutes. I’ve seen some offerings from RockBros and Santic—any first-hand experiences with those?

2. Rain Pants - Long or Short?
Curious what people wear on the bottom during rain. Do you go full-length rain pants, or just stick with shorts and deal with wet legs? I’m debating if long pants are overkill, especially in warmer temps. I saw some lightweight overtrousers on Ali, but not sure if they’re worth it for the occasional shower.

3. Shoe Covers
What are the best rain shoe covers out there that are actually waterproof and durable? Has anyone experience with the ones from YKWBIKE?

What do you guys think? Does this look like a structural failure to you?

Is it far too narrow?
I read of the 105% rule, which states that the external rim should be at least 105% of the tire width.
And the wheels I mentioned have an external width of 34mm, which is more than 105% of 30 mm.

Are there no downsides at all to have wider rims?

Yes I've also heard that from an aerodynamic standpoint, deeper front wheels make more sense.
But I would have tought, that a shallower front wheel would reduce the impact from cross winds.
Which Serenade model do you have?

so what's the ideal situation there? same real width, tyre slightly wider or rim slightly wider?
