Godzuki26 thinks there needs to be a Weightweenie Scott Scale 900 SL build in the USA. So here we go!

Who are you (no off-topic talk please)

I guess the question is, which Sram version could you tune to make the lightest? AXS has a 7g headstart, but my moneys on ye olde cable pull.

I didn’t get too far on the bike as the custom bottom bracket I have installed on the bike does not work. As mentioned earlier, the bearings are too thin and do not support the 30 mm axle of the THM crank. Spinning was ok but any torque caused the chain ring to rub the frame. I also noticed the stem bolts on the GrigioCarbonio stem came loose as I torqued it slightly under spec to not damage the 81 gram handlebar. I had to soft pedal back as I did not have tools with me to retighten the bolts. So, my initial experience on the bike was not good but this was a small test ride only before I tune it to make it work. I need to install a beefier bottom bracket and I need to use a good carbon paste and torque the bolts tighter without being afraid. I will post pics of the finished build once it is in a rideable configuration/status. I have some tweaking to do and have a lot of free time this weekend as my wife is busy and will leave me alone.

I need some Weightweenie tools so I got a Barbieri Nana pump. It is made of carbon and titanium. It is not the easiest pump to use but when testing it out to inflate my tires it does work decently with some effort. I obviously removed the decals and sanded it so it is matte like the frame. I also redid my mini tool to make it lighter. I used a carbon plate to make a new handle and replaced the heavy steel bolts. Now the tool is the size of a thumb drive.

I'm loving the custom multitool. I think it's inspired me to finally make my own, 42g toolmanator 5 is simply too heavy ;)

Ha! Absolutely brilliant that you are tuning your tools too! Thoroughly enjoying this thread.

The pump will kill you when you use it for a high-volume tire.

I carry this tool with the 6mm allen cut off:

@Marin a that’s a cool looking multi tool. As for the pump, I do what I always do. Start pumping with something useless, my friends don’t want to wait, so they let me use their pump.

The Maxxlite tires suck. Not quite as bad as the Furious Fred but still close. Too narrow, weak sidewalls, and no grip. I guess fast on hard packed fire roads but that was not the case. Switching to S-Works Renegade 2.3 tires and will run the tubless with sealant. Maybe I can save a little weight with Barbieri carbon valve stems. Also check out the C2Works Carbon hub axle that saves 10 grams on an already weight optimized rear hub.

In grams the weights of both suspension and rigid versions. The weight of the suspension version is slightly over 6000 grams so I failed at breaking sub 6. The weight will get beefed up once I put thicker tires on and go tubeless. I would need the GrigioCarbonio frame to break sub 6. You really can’t go any lighter on the rest of the parts I have used.

Weight in lbs for us Americans. Did I mention how I hate this Park hanging Scale because it measures in oz. I need the Alpine Scale that measures in hundredths.

nice....

I'd only swap the eggbeaters.... they are terrible engagement wise compared to what is available.

Hello. Thanks. It is not comfortable at all. I think the Berk Combo is not going to work as I find it too stiff. I will need to switch. I am not sure yet on the handling characteristics as I have not been able to really push the bike with the current tires. Once I switch to a tubeless setup I should be able to ride it better.

I am also having trouble shifting to the largest cog. I already tried playing with the limit screws as well as completing a master reset. The derailleur hanger does not go in far enough to shift to the largest cog. I realized this when I needed to use it the other day.
