Can the FM936 use a 165x45 shock?

No. Maximum is 165x42.5mm. Official maximum (according to Carbonda) is 40mm stroke. Read the earlier post in the thread. This topic has been discussed extensively.

I have a 150mm Crank Brothers Highline on my medium frame.

Almost finished.

Is there any option to put a 150mm dropper? I wanted to buy OneUp, but it's out of stock and won't be on sale soon. Has anyone tried the new Fox Transfer 2021?
Or should I just buy 125mm?

How does this frame perform as an XC race bike?
Im particularly interested to hear how it climbs on really steep climbs. I would fit a lockout front and rear but I can figure out form the Geometry chart if the front wheel will be more likely to lift up and loose traction because of the long reach and slack head angle, or if the bike will be more planted on climbs than most XC bikes due to the really steep seat angle which might place your body weight further forward relative to the BB than a more traditional XC geometry would. currently riding an A036 , saddle slammed forward. That bike has never felt good to me.

I was also considering the FM258-B-SL which is the Scott Spark copy and weighs under 2kg in size Large. But it doesn't take a Trunnion shock and isn't available until the end of January. I need to buy a new shock anyway so figure it makes more sense to buy a trunnion shock that i will be able to use in the next frame in 5 years time. My current Monarch XX shock leaks hydraulic lockout fluid at the shock so i cant lock it.

This frame is a really good climber. Better than I thought it would. I would say it climbs as well as my 2017 Scalpel. I have some silly steep climbs on my trails and I actually enjoy climbing :)

Add front and rear lockouts and you'll have yourself an XC racing weapon.

Couple more questions and notes:

Is the consensus to go with 170 cranks on this frame due to the low BB?  175 are a lot easier to find.

I would have preferred BB92, since it has been trouble-free on my two other carbon frames, but BSA was all Adam had available in large standard weight.  The good news is that I already have two unused Shimano BSA BB's that came with cranks on my other bikes.

I already have a 740 mm carbon bar and 70, 80, and 90 mm stems.  I'm guessing the 70 mm stem would be the best starting point, but might need to go shorter.  Any suggestions?

Lastly, I was thinking about trying the Novatec 791/792 hubs due to the low cost.  Anyone have experience with them?  Alternatively, but for a bit more money, I've had good results with Bitex hubs from BikeHubStore.  I always use Sapim Laser spokes.

Definitely 170mm for me with this frame. The BB is among the lowest I've ridden. If you mostly ride groomed trails, by all means, run 175mm if you wish. Where I ride the 5mm difference (along with low profile SPDs) is significant with this one.

I am 175cm tall with long arms on a medium FM936. I am running an 800mm bar x 40mm stem. The bar is getting chopped down to 760-770mm soon. I wouldn't want a stem longer than 50mm with this frame unless I am going for an XC racing oriented build (I have a Cannondale Scalpel for that, so don't really want two similar bikes).

Novatec are OK. Not the best longevity, but good value for money. If going for a budget build look into ZTTO hubs (I think someone posted about them earlier in this thread). I built a set of wheels for a friend with ZTTO boost hubs and they seem decent.

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.

I don't know if I've asked you specifically. I've asked all over and lost track. What are you using for a downtube protector?

A strip cut out of EVA floor mat tile. Shaped with an exacto knife to be flat on the bottom and zigzag on the top. Affixed to the top of the chainstay with small pieces of double-sided tape and wrapped with a single layer of self-amalgamating tape.

Edit: Oops, brain fart there, sorry! I somehow read your question about the chainstay protector. The downtube protector is a piece of Kydex that I heated with a heat gun, then shaped right on the frame with thick work gloves gloves on, then affixed with double-sided tape to the frame.

Looks great dude! I love it too. Where are you riding though? The moon? Mars?  ;D ;D ;D

Egypt :). This is a hilly limestone desert just outside Cairo. Our terrain looks a bit like an alien landscape.

I have to say I do like the lines of this frame. The ride is fantastic, too.

Low bb didnt notice at all with 170 cranks! I was going down deep railway sleeper stairs on the trail and didnt notice a too low feeling

I also don't think the low BB is very noticeable. Not a big deal, has its advantages.

The low BB is the thing that stands out the most to me out of the geometry of this frame. I guess it all depends on the type of trails you ride. On my home trails (natural desert trails, loads of rocks and off-camber technical singletrack...nothing is groomed), pedal strikes are far more than the two other bikes I ride most frequently (2017 Cannondale Scalpel and a Titus Fireline with a 120mm fork...neither is known for a particularly high BB) and that's with 170mm crank arms. Love this frame, but I dare not run the 936 with a 100mm fork where I ride seeing how low it is with 120mm.

Got the replacement linkage from Carbonda (recall my issue was shock mount span 0.5mm too wide and hairline crack on the linkage). Tolerances are better, but not by much (thick paint immediately flaked off the inside of the shock mount points as I pushed the shock hardware in, resulting in a looser interface, but not as bad as the old linkage.


Old linkage on the left (shinier because I have resprayed it after sanding to inspect crack), new on the right.


Interestingly, the new linkage does not have retaining circlips on the bearings.


Fitted my needle bearing hardware kit


Everything seems good without play after torquing everything up. We'll see how it fares after a few rides.

Tell me, did anyone install the 165x38 shock? if yes, can you show pictures of how it is installed?

Yes, here is my medium frame with 165x37.5mm fitted:

So for the past several rides I've taken off the Fox DPS 164x42.5 and fitted a RockShox Deluxe RLR 165x37.5mm (which is a remote shock, but I don't have a remote for it yet). At the same sag (by percentage of stroke), the RLR feels more taut under pedaling and rides higher in the travel, but easier to bottom out on bigger hits (but it doesn't feel like a harsh bottom out on small to medium sized drops, though). Still feels plenty plush on rough trails.

My ideal setup now would be to run the RLR with a SID 120 fork both on a Full Sprint type remote. Alas, the Suntour Aion I currently have is so smooth and that I just don't want to spend the extra cash on the SID. I have a 2017 Cannondale Scalpel in my quiver with a Full Sprint lockout setup, so maybe I'll just leave the 936 as it is without lockouts.

Also, Adam @ Carbonda finally shipped me my replacement linkage. Will post an updage once I recieve it and check if they actually rectified the issue which is imprecise tolerances at the upper shock span.

Anyone tried how the the clearance looks with a non boost chainring ?
If so, with how many theet  ?

With a Shimano XT M8000 non-boost crank and 34T round chainring there is plenty of clearance.
The same setup with a 34T oval chainring, not enough chainstay clearance.

I made a downtube protector out of a Kydex sheet that I molded with a heat gun and used double-sided tape to affix it. You could do the same by cutting Kydex to shape for chainstay protection at the BB.


I tried heating kydex in the oven then forming around my lightcarbon frame. It looked nothing like the one I saw on pinkbike.  It seems like you have to get it pretty hot to mold it. Did you heat it in place on the frame? I thought about doing that but am worried about damaging my frame.

I can't speak for painted frames, but it won't be hot enough to cause any damage to the carbon.

Cut Kydex to shape. Heat in the oven or with a heat gun to the point of having the kydex sheet completely flexible. Put some leather or thick work gloves on. Bike upside down. As quickly as you can, mold the sheet to the contour of the downtube. Keep holding it to the downtube until it cools enough to hold shape. Apply double-sided tape and affix to bike.

It won't look perfect, but it does the job. You may have good luck with some factory downtube protectors if they're roughtly the right dimensions.

Talking abouit BBs, has anyone got an suggestions for BB protection? Beyond mastik tape. Also anyone have any suggestions about how to make a little piece of alu or steel for the chain ring protection on the chainstay next to the chain ring since mine was missing? :(
My BTLOS wheels shipped this week so I'm looking forward to a ride!
