FM1002 / FM1166 - 150mm frame

[endo.alley]

The shock bolt is 8x40mm, and you need bushings or needle bearings to fit 8x30.

I went with the RWC needle bearing kit since the eyelet end is the one that rotates on the FM1002 and 1001. So far it’s been great.

If you want to run bushings I’d suggest pressing out the metal ring that RS puts in their eyelets (for use with their full metal bushings) and running Fox DU polymer bushings.

I ordered an 8x30 bearing kit. After pressing them in I realize that the FM1002 stainless steel spacer bushing is for a larger than 8mm inside diameter. Closer to 9mm inside diameter. Bushing is 12mm outside, 8.02 inside. Do I get a different bushing or a different bearing to make this work? Or just go to the hardware store and find a plastic bushing that I can grind down to fake it?

As I understand your 8x30 bushing/bearing kit fits fine as it is but hardware required is 8x40 so additional 5mm spacers are required each side. However supplied spacers are internally larger than your 8mm bolt diameter.

I would say as long as spacers are laterally tight, there should be no problem.
Of course your 8x30 bushing kit should support the slightly improper spacers.

I was under the impression that the bolt was 8x40 so that it would clear 30mm for shock and bushing/bearing, with 5mm of frame/pivot on each side. Is that not the case?

That is correct. So 8x30 works fine with no mods.

I've taken the bike on a few more rides. Directional downhill trails and bike park laps.

This bike climbs perfectly in the larger gears, but some efficiency is lost when climbing in smaller gears. On my FM936, it is much easier to carry speed up hill and continue climbing in a smaller gear. The FM1002 is still much more capable while in a larger gear on steep technical climbs and maintains superb grip. In the future, I will try to always climb slower in a larger gear.

I wonder if the FM1003 would be a stronger climber. It's suspension platform looks similar to the CBF linkage on the Revel Rail.

This bike kills it on the bike park jumps and I'm looking forward to riding it at a resort.

I was hoping for a much beavier 936 with ok climbing capabilities for big days in the saddle... Or is still good for climbing an our or so uphill?

[casual_build]

It's very good for all climbing when pedaling the larger gears. Feels very efficient and has great grip. As the gears get smaller, more efficiency is lost on the uphills. The same is true for the FM936, just to a different degree.

I went with this. "Fox Racing Shox Shock Bearing Assembly Black, 8mm x 30mm"  It gave me some trouble. Since the inside hole diameter was closer to 9mm. And the FM1002 bolt was 8mm x 40mm.

Thanks for your info. Just want a bike next to the 936, not overlapping to much.
Waiting for Adam for a nice offer with a new rear for my 936

Yeah, I almost got one of those at first but went with the RWC needle bearing kit after reading about various problems with the Fox bearings.

I wish I had known. I was pairing it up to a Rock Shox Ultimate. It took some doing to make it all fit together.

After couple of emails with Adam, I'm now waiting on a size medium Fm1002!
Hard to choose which shock...dvo topaz, rs super deluxe, fox or manitou or even a sr suntour  triair3. Any Ideas?
Front will be 160mm lyric or dvo diamond I think if I could get it a bit cheap. Fox 36 grip2 would be great but to expensive.

Rest will be slx drivetrail I think wit 4pots slx or so brakes. Already got 30iw Nextie AM carbon wheels.

Personally I’d suggest DVO, partly because the Topaz is great at working well with all sorts of different kinematics…but Suntour’s high end models are similarly good — just not as “adaptive” as DVO’s fairly unique damper. DVO also has a very affordable factory custom tuning service and you can get 15% off with code REMY15 (Remy Metallier’s code seems to just work, permanently, for everything from their site).

With the discount it’s really hard to beat the price-performance ratio of DVO.

I think the 1002’s kinematic is decent for most stock tunes, but I’ve had a lot of frustration getting the past 5+ years’ Fox and RS shocks to work the way I want them to; Fox is almost always too harsh and RS too mushy/unsupportive. RS’ new spring backed IFP “Ultimate” dampers may be better at this, I haven’t tried them yet. I do like the fact that they’re silent though. Fox in particular is too noisy, especially their forks.

A Lyrik is certainly lighter than most DVO forks, and if you’re getting the new 2022 IFP damper Lyrik Ultimate that’s probably a very strong choice. DVO forks are a little heavy and definitely quirky in the long run when you have to service them — a lot of shops just don’t bother learning anything about their unique elements (OTT coil negative spring, seals and damper like different fluids than other forks and can swell up if you use the wrong kind).

You can always send their products back to the mothership for service but their past quick turnarounds have ballooned to the point (~2 months last I heard, was about six weeks for me last fall) where if you need something during riding season you’re better off sending it to an independent suspension specialist like Gearwork.

So if I were you, and it’s in the budget, I’d go with a Topaz and a 2022 Lyrik Ultimate or matching Ultimate-level Rockshox on both ends.

Oh, and BTW you can use any 205mm Topaz…they’re all the same shock just with travel limiting spacers in the top of the inner air can. I bought a 205x65 with no spacer. All you need is the 5mm, and although not always in stock at the DVO web site they’re almost always possible to find somewhere.

Thanks for your reply!
I do like the dvo's because of their easy service and if they work good damping.
But haven't got much luck with my sapphire. First one, there was an issue with to much play, so got a new one. Now After two years  the bladder/damper is broken and need to be fixed by cosmic sports in Germany (live in the Netherlands btw).
Will see if I find a good priced one..or a lyrik.

Check out Backcountry. They are selling the Rockshox 2022 models for a pretty good price right now.
