Of note, the trunnion eyelet with remote is starting to trickle out.

I am not sure if this is right eyelet…but I believe the same eyelet for the SidLuxe works for the DeLuxe.

NS  Manual:  ".........the frame is disigned to work with single crown xc forks with up to 120mm of travel................use differnet style of forks or forks with longer travel my result in frame failure , possible injury....."

The frame is designed for XC in terms of weight. But most people here want to use it for trail or enduro. You can see this in the statements you keep reading: tendency to recommend a larger frame with a very short stem; search for more suspension travel, "spirit of the (I think he means downhill) bike" ......I think: the real spirit (from the manufacturer)   is XC with 100/100mm!

You can do everything, but please don't be surprised if a part fails.

It is more involved than just swapping eyelets. In addition to the eyelet, you would also need the damper shaft, poppet valve shaft, piston seal head & corresponding shim stacks for the remote specific version of the Deluxe. Only the eyelet & the damper shaft are available through after-market sales.

Also, The SIDLuxe & Deluxe are two different designs, so there is no cross-compatibility. There are some SID luxe 165 x 45 Trunnion Remote shocks out there, but this also has two issues: 1. They are M/L compression/rebound settings, so they would need to be re-valved/new shim stacks installed; 2. 45mm stroke is too long for the 936, and will result in contact between the rear end & seat tube. While there is a travel/stroke limiter for reducing to 42.5 or 40mm, there is no official part number listed, so it is for the most part unobtainable at the moment.

Wrong. This is frame with "forward geometry", and it should be used with short stem. Slack head angle + long stem = worst steering ever.

I honestly don't think the FM936 is functional with a 100mm, I get pedal strike with 120mm and 2.4" tires. I don't understand how anyone can ride it on rocks and that kind of terrain, without damaging cranks.

It seems to me that I am being misunderstood: Manufacturer recommendation is 100mm travel and no manufacturer uses very short stems (~40mm).   Carbonda, Vitus, except NS-Bikes (they offer a 120mm version but with adapted rocker).

If you get pedal strike (often), maybe you should use a real trail / enduro bike?

With even lower BB height at sag? Are you sure this will help? :D :D :D
As for me, I ride this frame with 120mm fork and 170mm cranks, and in this setup it seems to be quite ok regarding pedal strikes.

Hi all,
I am thinking to buy a 936 frame but Vitus is going to sell the Rapide FS CRS at £ 2799, around € 3300.
Wouldn't Vitus offer be cheaper than thr option to buy from manufacturer the frame, all the other parts and build it ?
Any other alternative to Vitus in Europe (apart from NS and Bottecchia which are more expensive)?
Thank you

My build!

As the frame is the same as the Vitus Rapide I was toying with idea of just getting a Vitus as that was good value in 2021, but in 2022 the prices have jumped a fair bit for the same bike, so for me it was as good, if not better value to build up a FM936 myself.

I wanted a fast trail bike that I could race XC on if I felt the need. All parts are sensible, nothing excessive and all functional.

Superlight frame, with Scott Nude shock and Scott twinloc lever that I got to work with the SID ulitmate fork. 'Just Riding Along' XC alu wheelset, Schwalbe tyres, mostly XT transmission, brand-x dropper, fairly bog-standard finishing kit - weight with pedals/cage/frame protection/etc is under 26lb and cost me just over £3000 give or take - not including the 4iiii power meter I decided to get.

Very happy with it. Already raced XC on it and it did very well. Happy I hunted out a remote lockout solution for suspension - love it.

:)

Hello,

I have a Fox DPS 165x42.5 on the way. Is there any hardware, bolts, or bushings I need to purchase to fit this shock to the FM936?

Many thanks!

You'll need 22.2x8 bushing. This one will fit:

Awesome! Thanks for the link.

I need something a bit quicker (USA)

Would this work too?

Some posts back I said pedal strikes were few, boy I was wrong, I'riding with 100MM front and the Xfusion 165x40

Any suggestions on making the bike higher? Run less sag? Bigger shock?

Otherwise the bike is awesome but rocky climbs this thing sucks.
