Will a 42/52 tapered head tube fit a standard tapered fork?

Yes, that should be an IS style headset for 1 1/8" upper steerer and 1 1/2" lower steerer.

Is IS just the bearing in the frame or do you still press in cups?

IS involves bearings directly against the frame. Ensure the bearings have the same taper angle as the frame and headset.

I have a pre-2010 RC2 that I lowered to 100mm. I cut the spring (blue) and left it slightly long in hopes to keep the fork stiff..it was an absolute PITA to get the compression cap back on because I was pushing down on the spring. Mind you I'm not a 200 lb gorilla. Essentially I added a bunch of extra preload to the spring.
My issue is that the fork is not stiff enough and I'm assuming the only way to remedy this is with a yellow spring or some other equivalent? Will it be difficult to source one?

I recently acquired a new bike and it has a Manitou Sherman fork on it. It needs a front axle, but I am having difficulty figuring out what it uses and where I can find one.

I believe it needs a 20mm Hex-Lock non-boost through axle, but I'm not entirely sure if that is correct. All of those I see for sale online are running over $50, which is a bit more than I am willing to pay, although I'd be fine buying used if anyone has one for sale here in Lower Mainland, BC

I just want to make sure I am correct in thinking that it is a 20mm hex-lock axle I need.

I currently only have a picture of the front of the forks, I now realize that the picture I took of the dropouts is way too blurry to be of any help. I'll try to get a picture up later today when I get home.

Manitou Sherman fork on the project DJ will be removing the front brake

Pretty sure that fork is before the says of boost and 15mm axles all together. There were few forks that were not a standard 20x110. Your's is almost certainly a standard 20x110. Having said that, I don't think any other axle with work other than Manitou's. Contact them directly, you might luck out.

I strongly suspect they won't fit tightly enough and the post will rock back and forth. If the bottom edge of the post contacts the frame, you could crack the frame from the localized loading.

The Ripmo af does not have a 34.9 seat post diameter Big Grin

But seriously, try to locate one locally. Or order one from Jenson or Universal Cycles or ?

meh that was the one trade-off of cancelling the ripmo
I’ll check some shops tomorrow, i’d use jenson but the shop that ordered mine initially put their order through jenson, so not likely to get here any quicker haha.

If you don't mind it in silver, QBP has tons of them in stock in their Reno warehouse. Any shop can order from them and it arrives the next day.

The Chris King Dropset 2 is a 45x45 bearing top and bottom. Also the Promax IG-45 uses 45x45 bearings.
