Found this after removing the black primer.  Anyone know what it is?  Looks like maybe a tag or something?  It is embedded in a rather thick layer of un-reinforced epoxy in the downtube.

What did you use to remove the coat of varnish and paint from the frame, a solvent or hand sanding?
Did you weigh the frame before and after to estimate weight gain?

What are you guys using as a chain guide? Want something light that will fit.

I sanded the primer off down to the epoxy with 400 grit wet sandpaper (would not recommend, too labor intensive).  I didn't weigh before and after, but I belive the matte clearcoat I sprayed after is a little lighter but not worth it unless you just want to see the weave.  I used the Shimano chain guide SM-CD800 ISG05.

Two rides in, this thing rides like a Cadillac compared to the M2 Stumpjumper circa 1997 I've been riding.  BTW the grip and pace is unreal.

Some of the details of my build.  Shock pivot pin threads were kind of buggered up, so made a new Ti pin with some stainless bolts.  Also turned a custom 8mm to 1/2 bushing for shock mount out of TECAPEEK.  Accents in copper, plan was for "dolemite" to be in chrome, but that failed miserably so black for now.

Did you modify the shock pivot pin in length?
Mine is around 2mm too short. If I tighten the screw the bushing for shock mount will be clamped in a way that it can only move the rear shock with quite big force.

Thanks

I did not modify the length, did not notice any need to.  I did make the bushing also though.  My shock pivots freely.

hi,

how is the ride?
what about the suspension performance, both when pedalling and when going fast downhill?
and what about flex in the rear?

I'm considering this as my xc ride, with some races to manage.

thanks

I attached the FC-M8100-1, which has 52mm. It's fine. I use 32T chainring. I don't know if you will get troubles with clearance with larger ones. Shifting is also very good, but that's what I expected from shimano as the crank is designed for 142 as well as 148mm rear

Thank's. I want to buy 52 mm because I will use carbon wheels from my old bike non boost for now. Will add conversion kit. Let's hope it will works fine.

I bought them because they have a smaller q factor.
I wanted to have the smallest possible value. I feel unhappy riding pedaling with the feeling of being a cowboy.

Hello, I am looking at this model and your photos help a lot, thanks
In theory, what brand model does this FM909 look like?
