Carbonda fm936 Thoughts

[NasiLemak]

I considered changing to a 42.5 - But my concern is that the increase in travel will lower the BB?

Its my do-it-all bike but also mostly to race XC on technical natural trails during the summer - so I like a machine that is lightweight. Contemplating returning it for the 42.5.

In the future I will be running a 110 (or 120) 35 sid ult.

Thanks!

You'll be happy! I did and Enduro race and the Swiss Epic the same summer last year with it.
With a 120 Ultimate and 42.5mm here's the build: http://chinertown.com/index.php/topic,2079.msg26737.html#msg26737
Swapping the wheels and tires for the enduro.

Beautiful Build! How did you source the remote lockout for the sidluxe?

Carbonazza if I just change the Fork and leave the Shock 165x40, will the BB be higher than changing both? Really like the bike but pedal strikes are pissing me off and I´m already running very little sag

I didn't see that one before sorry.
Not an expert in geo-dynamics 
My guess looking at the pivots and bike, a longer fork will make the BB go up.
Both shocks are 165mm, but a 42.5, will allow the BB to go a bit lower at full compression.

Offset eyelets for the shock mounts? Shorter cranks? A Slack-R headset insert will raise the stack height 10mm. Probably 5mm on BB. Considering that on y FM909 next spring.

Hi all,
I have a question regarding bearing replacement.
I run FM936 for 2 seasons and 7k km quite hard (trail riding, XC-racing) in dry conditions.
Last year I serviced bearings in workshop with new grease. This November I broke shaft of the rear shock and went to another workshop for repair and they told me that bearings required change. I do not trust them because they invent a problem even when there is none.
Thus, the question is: how long do stock bearings last? Is it the time for replacement after 7k km?

I don them every year, so 4a5k a year. But depends when and where you ride.
7k is good lenght I think.

Hard AM/enduro riding can easily wear out most stock bearings (even on branded bikes) in less than 1,000mi/1800km. So even moderate XC riding will probably not be able to get away with several multiples of that. It only takes mild bearing play to put increased stress on the frame and shock.

I usually suggest new bearings every year, just because late season riding tends to be messier and harder on them here in New England USA. Mileage is only part of how you measure bearing life.

Usually you don’t need to replace all of them, just clean and regrease some while replacing the most worn ones — usually the main pivot and rocker arm pivot on common linkages. Get Enduro Max bearings and you may be able to go multiple years without replacements.

Just got my frame, anyone have an issue with shock alignment on there 936?  If I tighten the bottom trunnion mount bolts first, the upper shock is misaligned by a few millimeters.  But when I loosen the trunnion bolts then install the upper pivot, it gets more aligned.  Pictures attached.

also, the shock was a super tight fit at the trunnion mount, is that normal.  I really had to push to get the shock between the trunnion bearings.

This doesn't look good. You'd better contact Carbonda ASAP. If you leave it "as is", you'll get quick wear of side surface of shock's shaft/stanchion.
On my 936 shock was aligned pretty perfectly.

It is most likely the shock that is currently misaligned. Take all the air out of the shock, then you should be able to rotate it by hand.

Make sure the trunnion bearing spacers are oriented correctly and fully seated.
