Thanks, I figure it's petty superficial but was still hoping I could get it to it's former shiny status using the ultrasonic cleaner. Plus I'll be cleaning it again in near future so might be good to figure out a different cleaning solution that doesn't strain it.

I’d be afraid of what CLR would do to the metal much more than tiny surface rust specks.

They're extremely simple machines and before you know it you'll be doing most of your own maintenance a few beers in with music blasting in the background while yelling obscenities at your friends. But do use a torque wrench on your crank pinch bolts and on your carbon bits. Some people say you just tighten it till you hear the crunching sound then back it off a quarter turn but ehhh.

. I did 2 ultrasonic cleans on a brand new shimano cn-m8100 using Zep citrus cleaner with hot water, followed up by an alcohol rinse/5min soak while I waited for my other chain to wax (91% iso since I can't find mineral spirits and like in CA).

Note to self: Be really loving stingy with loctite on suspension pivot bolts lest it makes it past the seal into the bearing, unless of course you enjoy the sounds of rice bubbles as you ride! Many frustrating hours later, cleaned and repacked with grease, noise mildly subdued.

A freshly waxed chain will rust while stored in a slightly humid garage. It's mostly superficial rust and comes off pretty much completely while riding. But also yes, store waxed chains in a dry environment if possible...in a plastic bag or bin.

I picked up some older mavic cosmics without knowing about their poo poo freehubs, and there's enough play that I can feel it pedaling. There's a grinding noise with any pedal stroke of any significant force. Does anyone have experience with putting new/oversized bushings or the hubdoctor bearing kits in mavic freehubs?

I am looking to put a cassette with a little more range on my 9spd road bike. It currently has a "standard" cassette and I was looking at the SRAM PG-990 9 speed 11-34. My hub is currently shimano/sram. So, the only things I should need is new chain and derailleur tune right?

Here are the specs for that one. https://si.shimano.com/pdfs/si/SI-53Z0D-000-00-ENG.pdf You can usually push them a little further than spec, but I am fairly certain you will need an adapter to make that reach all the way up to 34t.

Oh that boy's got a real small cage. 32 could work if you don't have too-compact rings at the front, 34 will for sure need a road link. E: what a beautiful derailer. However it looks like an 11-34 tooth cassette puts you 4 teeth over the wrap capacity if you're using a road double at the front. You'd be giving up a fair few gear combinations at the cross-chain ends if you install that cassette with a road link. Worse with compact chainrings.

e.pilot posted:and if it doesn’t a wolf tooth road link will solve that A wolftooth helps with reaching a larger rear cog than specced, but doesn’t help with an overall larger system capacity. CopperHound posted:Here are the specs for that one. https://si.shimano.com/pdfs/si/SI-53Z0D-000-00-ENG.pdf Yep, best case it’s a GS (long cage), and assuming the usual 16 tooth difference in the front chainrings, that only leaves a capacity of 21 for the rear. 34 - 11 = 23. If it’s a short cage whodatwhere has, a new Shimano Sora 9 speed long cage derailleur is cheap.

Thanks for all the discussion! So, it is definitely the short cage version. And upfront I actually have 53/39 so 14 differential. It will be a stretch for sure, but if it doesn't reach with the wolftooth then only $20 spent + a spare part for future and will look into changing derailleur e.g. sora.

I ran the same setup on my cobbled together “gravel” bike for a while (wolf tooth + short cage 6500 RD) and my solution was to set the limit screws to n the FD to not allow it to shift into the big ring! It was good for my use case on that bike (only gravel, and mostly steep stuff at that, never needed to be in the big ring).

Speaking of derailleurs... Am I right in assuming I can swap any Shimano 9-speed mountain bike style derailleur for any other in their line up? I've got a Trek FX3 I use for commuting all year in Montreal so it gets pretty beat to hell in winter with our rotating schedule of freezing rain, brown slush, and more salt than the ocean. The original rear derailleur is some kind of Acera (RD-M3100 or some such). The tension arm keeps jamming and making the chain skip if I leave whatever gear I was on when the arm jammed. The pivot is probably full of crud. I was going to take it apart last weekend for a CLA but it doesn't have the usual set screw that lets you pull the pivot out. Its a circlip embedded in the plastic casing hidden under a welded plastic cap. Pretty much designed to not be user serviceable. I want to replace it with a higher end model I can actually service. This town is going to make my next bike a belt drive.

Does anyone recognize what chainring has those standoff bolts to mount the bashguard?  I'd like a drop-in replacement for this double crank, just in 165mm, but I haven't heard from Tern what crank they specced. Though I suspect chainline isn't as much of an issue on a longtail, except for making sure your FD still works. What other 104BCD double cranks have a bash guard solution?

kimbo305 posted:Does anyone recognize what chainring has those standoff bolts to mount the bashguard? If it were me I'd have specced an OEM crank since there's much more variety than is available at retail and I could get the exact specs I want. I genuinely can't think of where to start looking for a crank like yours available at retail. Actually I don't know why I wrote this since it's not helpful at all, but here we are. E: that looks like the way Shimano TY501 or M361/M371 cranks mount the chainguard but hell knows if the bolt circle will fit.

I'm putting together a second wheelset for my gravel bike and I can't properly get the tire seated. Always seems to be a "lowspot" and I've tried all the tricks so now I'm worried about compatibility. Wheels are Giant CXR1s and tires are Giant Course 1 28s. Tubeless set up. Wheelset is hookless but apparently compatible with these tires. Any ideas?

Had to take a bike into the shop after spending a fair amount of effort replacing the chain and cassette and fiddling with settings but still getting jams and drops. Heard today that the rear derailleur spring was shot, so I feel a little better about that.

For major components just use whatever web based euro parts retailers are still abusing OEM status to sell Shimano and SRAM parts to the north american market for less than what shops pay their suppliers. When you need smaller stuff like bulk cables and housing just find a shop willing to sell you a box of bulk Jagwire at retail and then sell it by the foot. Your markup will be less than the shop you're buying from but you'll still be making money. For tubes just pay retail and mark em up a buck and if they say 'I can get them cheaper at X' tell em ok go ahead bring me a tube.
