350s heavy AF though, but they are reliable!

*laughs in total silence*

Try an Onyx Classic. They weigh about a King and a half, ha. Worth it though, to IMO. Also dead reliable and low maintenance.

[smmokan]

for 32h (from Fanatik's website)
King: 184g + 342g
Hope Pro 5: 188g + 312g
1/1: 165g + 295g
Hydras: 155g + 295g
350: 165g + 271g
240 EXP: 144g + 255g
OneUp: 142g + 220g

I wouldn't call that heavy AF. And ~$350 less than the 240s - that's a pretty bad $/g upgrade, even coming from a guy who puts Ti bolts on his bikes.

Anyone have time on the OneUp hubs yet?

i've got some slight play in my cranks, subtle but there, feel it in the pedals, can repeat it by holding all the other systems fixed and just sort of moving the cranks

XT 8100, ck BB thread fit 24, stumpy bsa shell

i checked the preload and the fastening bolts on crank itself and everything is ship shape there, not the pedals either , isolated those as well and they seem to be fine...
is it almost certainly play in the BB? or perhaps something intrinsic within the cranks (they're probably 200 rides old?)

bought an el cheapo shimano bb to throw in while i service the CK, well see if that alleviates things,

nerd question:
in reviewing the overhaul process, i reviewed the proper install alignment of the spacers etc. It's interesting- in almost all other threaded bb, hope shimano, others, it calls for a cup spacer between the cup and frame 2.5 drive side, pretty standard.

On CK it says to use SPINDLE spacers, 2.5 drive side, between cup and spindle

whats up with this? could you just install the CK like a standard using one of those standard 2.5 mm cup spacers? is there some load advantage to using spindle spacers? are the cup thread lengths not accepting of a cup spacer?
Hope, but same as shimano

Do floating rotors decrease brake noise? Shimano Zee calipers, fwiw. I put a new-to-me wheelset on the Smash and since my old rotors were at 1.5mm (yikes!), I ordered some no-name stainless rotors from AMZ that had good reviews, and got a set of MTX Gold for the front despite shop guy at Absolute warning me they'd be noisy, since I'd heard they were the sh!t. Got them bedded in properly, and now when they get a bit of heat into them, the front howls. Seems like a floating rotor would change the vibration frequency and thus the noise, but I thought I'd ask here first. I'd sure like to keep the MTX Gold pads, as the power is as advertised, but damn they are loud!

I'm at about 50% success rate on MTX golds being super loud. Thicker rotors seem to be quieter. Currently having good luck with galfers and hayes rotors. I had bad luck with magura rotors. None of them were floating.

I run Red's bc they are quiet, though not as much "whoa" as the gold.

I rode with a guy (~230 lbs) on a full power ebike a week ago, who had Hope floating rotors. I have no idea if they're noisy while descending, but I could hear them pinging from several feet away as they cooled down in between sections of trail when we stopped.

My new MTX golds also became loud AF by the end of their first day. Earlier bike I put them on they were not loud at all.

MTX does say you might need to prep the rotors if coming from metallic pads and I definitely did not do that...

Can confirm MTX Gold squeal like Pulp Fiction Pig. Especially paired with Magura rotors. Fuck. That. Shit.
Good luck recently with Galfer Pads and with either Galfer Rotors (1.8s for trail bike) or Sram HS2 (2.0 for the DH rig).

Edit to add: Pretty stoked for my mini-discovery. Realized the keychain spoke gauge that comes with the Park TM-1 tension meter is perfect for measuring rotor thickness. Quick interwebz hunt shows its unobtainium for whatever reason....

What is this bolt I found while recycling the box my Transition Sentinel frame came in? Looks like a T25 with a hole drilled axially through, forgot to check the size though. I did take the frame to a shop to have them press in a headset so it might have fallen in there.

Another "what rain jacket are you wearing?"

Thanks for the responses to this. Neoshell has been my go-to for ski touring for years. I'll give it a try for summer activities. Looks like there are a few super sales on the PI and Spesh options.

I’m installing Magura MT-5s on my new trail bike—pics coming once it’s built. The levers and calipers look to be identical. Does it matter which one I mount as the rear?

They can go either way. The part numbers are the same for front/rear/left/right. They come with long lines on both, so you can mount them what ever way you want.

I have a weird chain noise problem and am wondering if anyone else has experienced this or knows if there is any way to fix it.

I have the Stans wheels that came stock on my bike - 2020 Fezzarri Delano Peak. Over time a weird problem has developed where I get bad chain noise in any gear above 5th when riding rough terrain and hitting something hard, but none below. My chain is short/tight, my clutch is tight and I have serviced it recently. I have a chain noise damper thing on the chain stay and can’t even see if/where the chain would be hitting anything. I even just re greased the freehub and replaced the freehub bearings. I’m fairly certainly this is pedal kickback chain slap where hard hits are engaging the freehub. It’s the “durasync” freehub without a lot of engagement points. I can tell the noise is the same noise that happens if I quickly stomp on the pedals so that the hub engages abruptly. Has anyone else experienced something like this? I can be riding a tech downhill, getting this noise, then shift down one gear and it is pretty much silent.

[Spencer123]

We are moving from SLC to Bellingham in October. My wifes Code RSC's are about ready for new pads. Anything to know about what works best for the wet winters? Right now she has the stock Sram metallic pads which havn't given her any issues. Metallic vs organic up there? Better after-market options suited for the climate?

Thanks!

Which rear mech? Shimano clutches in my experience need a service around 700-800mi. Took me a while to figure out what was causing problems, but this is important. Don't have the clutch problem with SRAM. Basically the clutch gets very stiff and grabby, and will not spring back. Service is a 15min job.

Jesus H Christ... looking at a 2022 Giant Trance X Advanced Pro 29 frame...

What size BB does this frame actually use? Giant's website specifies it as "SRAM Dub PressFit". No shit.

I think it's BB92, but have no way of knowing for sure.

[wendigo]

vital has it at 92

I have the Shimano XT and have fully serviced the clutch. It feels normal - like the ones on my friend’s bikes.

BB92 was the Giant standard for their 2017-2020 bikes, I'm almost sure it still is.

Thanks, Dee. It looks like the only thing I need to change is the direction of the bar clamp so the little arrows face up. I appreciate the help.

Anyone know or have experience with a bike fitting system called id match? https://www.idmatch.cc/en

Started doing longer road rides and am experiencing really bad lower back pain now so thinking it's time for a proper bike fit.

There's a local guy who does bike fitting using the above system. Seems a touch gimmicky to me but I have zero knowledge in this area. Anyone use it by any chance? Thoughts?

A tool is just a tool. They can make the job easier, but it's the person running the show that makes the difference.
The biggest issue with systems like this is that they are decent at getting people within a "box of acceptability". Your knee angle should be this, hip angle that,.... etc.
That may help your issue, or you may be someone who can't be in a normal box.
