Less pricey.
Geometry is great for modern XC, but i have a doubt on the main pivot location. It seems a bit too low (compared with the new LCFS902 from yishun) so we must expect degraded antisquat with big chainrings...

I am not seeing a whole lot of difference between a 036 and the FM06
I copied and pasted a transparent image of the FM06 on top of the 036 image.

The head angle is different on the FM06
The rear stay has no pivot on the FM 06

The frame size is a bit larger in the FM06 image but you can move the transparent FM06 image around and line up the BB and fame tubes to do a compare

I would argue that a 1.5 degree change in HTA and no Pivot near the axle are very significaht changes.

I'd agree. Not to mention shorter chainstays. The FM06 is clearly more up to date.

That said, if you're considering paying $1400 on eBay for that frame, just buy a Yeti ASRc on CC/BB for $2200 and get a warranty AND a Fox DPS Factory shock.

Buying a shock for that frame puts you most of the way towards the Yeti, which this frame is clearly trying to replicate.

$1,400 is way too much for a Chinese FS frame. I think that eBay listing is about double what you should be able to find it selling for through places like XMcarbonspeed, Workwell, HungFu, etc. I would expect the price to be closer to $700, like the IP/FM/CS-036 (which is even cheaper these days).

the price in Hong Fu its 660 -700 usd

Has anyone installed a BB30 bottom bracket on the 036 frame?
Is it actually BB30 (circlips and bearing pressed into BB housing)?
Or, are they actually PF30 - which uses pressed in cups?

Mine was a normal BB30 with circlips... but PF30 didn't exist back then

Thanks two-one,

Ever had any creaking/problems with it?

I'm.sure mine must be the same. They said BB30 when I bought it but as I was running Shimano cranks I never bothered to look to see if it had grooves for the circlips or measure the diameter of the housing to confirm.

Ehmm... i've had to replace the bearings more often than my older hollowtech cranks, but luckily they can be ordered cheaply online (its just a simple 6806-2RS bearing). BB30 sealing is always poorer than modern cups. It also depends on the preloading system. My FSA crank has a preload collar that has to be turned to reduce sideways play.
One trick is by buying aftermarket enduro seals for BB30 that creates an extra sealing layer, and mount with loads of waterproof grease.

Thanks for the tips.

Just ordered a BB30 power2max S-type power meter so guess I'm stuck living with it for a while. Will have to keep an eye on the bearings and maybe a spare pair on hand.
Cheers

Hi all

Got my main pivot replacement bolt this week from hongfu.Got 3 just incase.
Thinking about it Hongfu are likely creators of fm036 if those production photos are to be believed. No one else could source replacement bolts.

Custom LaMere Boost 148 Rear for HM036

We just had a Boost 148 custom carbon rear end made for the popular open mould 29er full suspension HM036 (and many other names) frames..... fits 3" tires, we beefed it up made it super stiff and burly with nicer pivot points.

I like it! Looks like it will be a popular choice as 29+ gains popularity.

What do you mean by nicer pivot points?

In order to accommodate 3 inch tires, I am guessing that only the lower chain stay section is what you are talking about replacing on the 036 frames?

The upper section that leads up to the shock pivot is the stock one?

Also, more detail on the nicer pivot point statement?
Different bearings?

Are you selling the lower section?

We need more detailed info please

Dikkie · Nov 9, 2016

Imo, the upper section looks beafier too and the flex comes from the main pivot, being quite narrow basewise. Same issue with the upper links...
I'm critical about the custom-Lamere-rear feeling stiffer?

Possibly Lamere would like to quantify how much the lateral stiffness is improved, possibly by side loading the frame and measuring the amount of deflection, then comparing that to the deflection in the stock -036.

hey guys,

does anybody has this frame and any experience about the frame?
What do you think about the geo?
Thank you very much for your informations.
