Can I use RockShox fork fluid in my Olin's DH-38? Or do I have to find that specific oil they recommend? Cuz that seems pretty dang hard to find.

Hi! I got a 2015/16 Giant reign the other day and discovered some pretty nasty cable rub on the lower link, right up against a weld. Safe to ride? I didn't even know this level of cable rub was possible to be honest, it really ate into it

You mean this little groove near the weld at the middle of the pivot?

I wouldn't be too worried about it. Just try to make sure the housing doesn't go back in there, or maybe try a different routing method altogether.

Yeah, that one. I wouldn't think it'd be a problem, but simultaneously horrified that it dug in that deep into a solid chunk of aluminum

I've seen worse. I wouldn't lose any sleep over it.

Spiral wrap is your friend, doesn't stop scratching but it's not hard enough to frett away the aluminium

Hi All,

Had a question as to which adapter I would need to purchase for my YT Decoy as I am upgrading my brake set up from SRAM CODE RSC to Shimano Saints 203 front and rear discs?

Assuming your current rotors are 200mm then all you need is a 1.5mm washer on each bolt, under the new caliper, to make it fit the 203mm rotors

How do I know the maximum rotor size my bike could take? It is a Vitus Nucleus 29er VR 2021. Thinking of putting a bigger rotor up front and moving the front to the back

Front should be good to at least 200mm and the rear you will have to check with the bike manufacturer/website. Sometimes the rear has more issues with tubing interference.

.

It should be written on the rotors, alternatively, the specs say the front is 180mm and the back is 160mm

Try it. Put the front rotor on the back wheel. Take the caliper spacer out from between your front brake and the fork, and put it between the back brake and the frame. As long as the rotor doesnt rub on the frame and the caliper all lines up properly without interfering with anything, then 180 at the rear should be fine.

I'm not sure id be keen on having a 200mm front rotor on a fork with quick release dropouts though. I've seen powerful brakes yank the wheel right out of a fork before. I'd stick with 180 front and rear until you upgrade the fork to something with a thru axle

oops didn't realize it was a qr dropout I didn't think they even made forks with those on them anymore.

That's a great idea, thanks. Otherwise might just have to go externally routed, or the ole analog dropper method Wink

Ok i have two potentially stupid questions;

1) I am attempting to fit a 230mm shock off of a santa cruz onto a rocky mountain, but the bearing mount is making things seem unlikely. is there any way to change the hardware/add pieces to get proper fitment with these, or are they sort of SC only?

2) What is the safest way to knock out a pressfit bb at home without a bearing press?
