Re: Carbonda fm936 Thoughts I also received my frame this week with a stunning (IMO) paint job. Minor paint scratch at the chain stay unfortunately but I'll live with it.
I will be building it with a RS SID Select RL 120mm fork and RS Deluxe Ultimate RCT 165x40 shock.
Carbon wheels from Speedsafe and mix of XT/SLX components. Should hopefully be able to hit ~11kg if my calculations are correct.

Re: Carbonda fm936 Thoughts
Hi Folks,
inspired by colt_seaver's building thread in a german forum, i spent the last days reading all 72 pages of this thread :o (who needs netflix? ;) )
I like the FM936 more and more... already have a spreadsheet set up to calculate price and weight of a bike based on this frame.

I stumbled across a few comments about poor climbing performance.
I am a fast tourer and marathon rider and my current "do it all" bike is a not-so-light carbon hardtail (IP-256SL if sb knows). I really like steep uphill challenges and eating altitude meters.
Problem is, i am a total coward going downhill: The smallest feel of sliding or the rear wheel getting light leads to a complete mental blockade. To overcome that, i think about using a more down-country or even trailbike-oriented bike. As i have a very long torso for my size, most common bikes on the market would be too short for me, so the FM936 should be just right for me.
Thing is, i don't really want to sacrifice uphill performance. So hands down, how much worse is the FM936's uphill performance compared to a hardtail?
Do you think the FM936 will meet my needs, i.e. giving me a fast touring resp. marathon bike with much more downhill confidence?

Is it worth the effort (money/weight) to have a rear shock remote lockout? I like standing up in the pedals for spontaneous give-it-all sprints. The only full suspension i rode the last years was a Giant Reign 2, wich was an absolute pain in the ass in this discipline (yes, different bike category).

Also, does sb have an idea how much weight is saved by opting for SL in size XL? Can i expect 200 g?
colt_seavers had 2182 g including rear axle for a standard XL.
I try to figure out where to save the most weight for the least money. Sub 11 kg with dropper post would be nice, but budget is limited.

A couple of answers for you in no particular order.
My current full squish (Evil Following MB) climbs better than my hard tail on 90% of the terrain I ride. Anything that isn't smooth, and the FS does better. Lots of rocky, rooty and rutted technical climbs where the FS does much better because it is so much better at maintaining tread contact. Set the suspension up correctly and I doubt you'd miss your HT on anything but the smoothest climbs.

 I have never used the lockout, even on the street or smooth fire roads. However, my XC racing buddies use remote lockouts and both swear by them.

Carbonda shows 150 g difference for the SL in size M. I doubt you'll get 200 on an XL and even if you did, you could probably save more weight spending that money elsewhere.

This bike will shock you with how much better it feels going down than the typical XC HT. The geometry gives it so much stability. It's not an enduro, but drop the seat and point it down and have fun.

Finally, you won't hit 11 kg with a dropper unless you have lots of really lite parts already, friends who will sell you really lite parts on the cheap or you spend a bunch of money. Limited budget and lite weight don't really go together. Budget Chiner lite weight wheels, tires and cassette alone will cost you about $1400, add in fork cost and you're already at $3k with the frame. Of course, if you wanted an 11 kg factory built bike with similar geometry, it would cost you much more, Transition Spur, XX1 size M, 11.2 kg, $9k. https://www.transitionbikes.com/Bikes_Spur.cfm

Re: Carbonda fm936 Thoughts You can add the float DPS to that list if you are willing to have someone add the spacer for money to make it 42.5

Re: Carbonda fm936 Thoughts

Currently i wonder if Gripshift & Twistloc will fit with current Shimano brakes... i saw some Pics that don't look too well. Looks like trial & error, i guess.
I have SID Select twistloc, fits well with shimano M8100. I'll send a pic tomorrow :)

Re: Carbonda fm936 Thoughts I got 11.75kgs including pedals, stainless bottle cage, and a heavy saddle.

The weight of my XL SL w all included bits was 2098g.

I think this is an ideal marathon bike.

I am 170lbs and have run the Sidluxe shock at 200psi and 180psi. Still not getting close to 42.5mm stroke.

Re: Carbonda fm936 Thoughts Hi, here is my table of weight and price.
I would like to buy a 165x40 (or 42,5) SIDLuxe with remote, but I can't find it for sale... Or a DT Swiss 535 (all mountain) with "2 in 1" remote.
The bike will be around 11kg

Re: Carbonda fm936 Thoughts Are you sure 387g for both front and rear brakes ?

Re: Carbonda fm936 Thoughts
A question for those who've built up the bike with SID 35 Ultimate/Select: any issues with knocking due to loose bushings or damper leaking oil? I am about to pull the trigger on one but reports of bad QC are scaring me a little.

On French forum, a lot of people reported such problems on the first SID 35 released. They send their forks for after sale service, Rockshox changed the bushing and problem solved.
I don't know if Rockshox solved it on first mount.
