Carbonda fm936 Thoughts

[ilyamaksimov]

Ilya, do you use 170 or 175 mm cranks? And if 175, how it feels regarding hitting obstacles (I mean pedal strikes)?

Changed 175 to 170, touched the roots from 175

Sorry if this has been asked before but thoughts on normal vs superlight?
 
what did you choose. carbon layup better on the superlight?

Ordered the fm 936 today in Size M.

Did anyone already run the frame with a 130mm fork. I already have a Pike Ultimate with 150mm travel which i want to use but unsure if i should go down to 120 or 130 mm.

As this frame has really low bottom bracket, so I think there will be no problems using 130mm fork. Keep in mind that in this case you'll get headtube angle about 65,5 degrees.

I was on a quest for a super light bike, so shedding some grams on everything is a must.
Otherwise it is probably not worth the cost.

Hello all,

Reporting back after building my bike up back in the spring.  I've only put ~500 miles on it due to work and alternating rides on my hardtail.  I've enjoyed the bike a lot.  It does seem to be at its best in high speed sections.

Today I was doing a little maintenance and took the suspension apart for some inspection and cleanup.  All the bearings and pivots were still tight and in good condition, so I just cleaned, re-lubed, and put everything back together.  However, while tightening the hardware using a torque wrench, I stripped out the head of Torx screw for the rocker pivot.  I'm sure it was partly my technique, but perhaps the screw wasn't the highest quality.  So I'm currently stuck and in need of two things:

1) advice on how to remove a bolt with a stripped head.
2) help locating a replacement screw of higher quality.

Anyone have any suggestions?

Thanks!
Ted

1) advice on how to remove a bolt with a stripped head.

Drill it a bit deeper, then use something like this: https://www.aliexpress.com/item/1005001707877026.html

OK - I got the stripped bolt out!

Now I just need a replacement.  Anyone know what type of bolt it is or where to get one?

TIA,
Ted

Perhaps?! If you stripped a Torx head without overtorquing the bolt, the bolt was clearly defective, either in manufacture or (my bet) material choice. That just shouldn't happen.

...That just shouldn't happen.

Welcome in the world of single-use Chinese bolts 
We should list all the bolts, and find reliable alternative ones.
I've ordered a bolt kit, and will measure them when they arrive.

Cracked the chainstay on my 936 today, pedal strike then crash.  Was hoping it was just a crack in the top coat, but now I can see water weeping through crack (from inside the chainstay).     


I'll see what Carbonda says, not expecting a full warranty here.  I've put about 2200 hard miles on it so far.

my chainstay cracked at the point marked with the arrow along, through. Adam wrote to saw them and sent out new ones as soon as they were ready.

(received new ones today)

Crazy, my chainstay cracked right behind the yoke as well, but on the lower seam on the inside.

Curious, is it a normal or a light version?
thanks,
