    Hi Peter

    Can you publish final full geometries for the frames please now you have production samples ?

    Also what is the weight of the frame in the pictures too please ?


    Thanks


    P.S. And pricing woyld be great too.

    No final fully geometries yet, we still have to improve some details, sizes 19'' and 21'' geometries will be drawn after we finish the improving and completely confirmed.

    The weight of the 17'' sample frame is 2300g.

    Sorry, I hope you could understand why I don't want publish pricing here.

    Thanks Peter no worries.

    Do you think it would be possible to run an "E-type" front derailleur, the type that attatches via the BB cups on BSA style threaded BB's ? I realise cable routing would need to be worked out (External stick on guides perhaps ?) but it would be great if we could run 2x and not limited to 1x.

    I will shoot you an email r.e. pricing if that's ok ?

    The weight seems good too.

    I'm guessing it runs a 165mm i2i shock similar to a lot of the Chinese carbon full suspension 29er's yes ?

    So what's the max tire diameter on this? Will 29+ fit?

    Any restrictions on 29+ rim width Peter ?
    Could I run 29" x 42mm carbon rims and a 3" tyre or is the max something like 29" x 35/36 mm rim with a 3" tyre ?


    Any pictures of a fully built up prototype you wish to share yet please ?
    Or any pics just as a rolling chassis with either 26" x 4" or 29+ x 3" would be great .


    Thanks once again Peter

    Someone has to make a 197mm rear end frame like this. That's all I have been waiting for.

    You'd essentially be asking for a full suspension fat bike that would fit 5" tire, as that's the only reason for such wide hubs. If Salsa or Borealis aren't making such a bike, why would an overseas company risk so much on a design like that? You're talking niche market of niche markets...

    Maybe but they used to say that about fat bikes and then about non offset rear wheel fatbikes and then about 197 rear fatbikes. Just because salsa or Borealis don't make it, that doesn't mean squat.

    Additionally a 197 rear also makes it more likely to fit 29+ and 27.5+ wheels. That's one huge reason to go this route.

    Ride report is right! I would say just take a look at anyone with a carbon Bucksaw running 4 inch tires and theres your ride report. Its no Salsa for sure, but I would dare to say it could be on par with one with the right build, especially the rear shock!

    A Bucksaw frame, which this is obviously a copy, fits 27.5+ wheels easily. Also easily fits D5s with room to spare. Unless you NEED 4.8" tires, there's no compelling reason for the 197 mm rear end.

    It does seem to be a blatant ripoff of a licensed (patented?) suspension design. I guess it doesn't matter because it's made in China?

    197 and 5" tire clearance would make it have a long-ass wheel base. Just sayin'

    Also, for people calling this a blatant rip off of the Bucksaw, there are some very obvious changes. I wouldn't go as far and say it will handle like the Bucksaw. There are some different pivot angles and the leverage ratio is probably a tad different. Which have fun tuning your shock to the frame. When you buy a Bucksaw, the shock is custom tuned to the frame. All FS bikes from the big name companies come with custom tunes on their shocks

    The frame shock question is why I am going to go coil over if possible since the ability to tune is much greater than air shocks.

    Right on.


    PeterXu, what tune shock would you recommend for this frame?

    True and true. No need for 197 spacing and 5 inch tires on this type of bike. 425-445 mm chainstays seem to be the sweet spot for more aggessive fat bikes and plus size wheel conversions. Yes, it is void of a custom tuned shock, but this is also just a bare frame costing 1/3 of the big boys custom carbon frames/shock! I would be willing to bet with the right shock setup it will still rip with the best of them...just my 2 cents.

    Thanks for the clarification on shock size.

    As far as cranksets go I found the RaceFace Turbine Cinch (RF169) and their BBBSA10030B6 bottom bracket which I believe are a perfect fit:

    Race Face

    What other crank/bb sets will fit?

    Thanks!

    SRAM X1 1000 Fatbike Crank 1x11 GXP, SRAM GX 1400 Fatbike Crank Black 1x11 GXP, SRAM GX 1000 Fatbike Crank Black 1x11 GXP, just to name few cheapest.. Also with Sram cranks one need Sram GXP BB, SRAM Bottom Bracket Truvativ GXP XR | BSA Fatbike

    All that are 170-177 rear, with 100mm bb

    All these have Q-factor above 200 (width of cranks and chain line 66+ )

    Only some Sram xx1 cranks, have Q-factor 168 and that can be tight.. there is also 201 model...

    Also;
    RACE FACE Fatbike Crankarms Turbine CINCH for 170 | 177 mm Hub + RACE FACE Bottom Bracket BSA for CINCH System Fatbike is Ok. There is also carbon model, etc.

    One nice is; BOR Fatbike Crank FB557 Basic 170/177 SmartSpindleSystem

    Rear shock is 200x51mm, 120mm travel, 8mm bolts, down is 40mm wide and upper 22,4 wide spacers.

    Headset is 42mm upper and 52mm down, IS (integrated)

    Thanks for the helpful post, Jukahia...you read my mind including all the extra information. I switched to the SRAM GX-1400 which seems like the perfect price/performance crankset.

    Here's the shock and bushings I ordered:

    Rock Shox Monarch RT3 Mid Tune | Air Shocks Shop
    Rock Shox Bushing for Monarch/Vivid 22.0 x 8mm | Rear Shocks Accessories - Rock Shox Shop
    Rock Shox Bushing Set for Monarch/Vivid 40.0 x 8mm | Rear Shocks Accessories - Rock Shox Shop

    I hope those are the right busing sets -- it's the washers or whatever you call them that I'm worried about -- and that mid tune shock works out for this frame's leverage rate.

    Peter and I'm guessing his workmate Jukahia ... you're great to work with ... thanks!

    Well i`m just a biker from Finland... Yes, I have also ordered CS-001 and sent many e mails between Peter. I have drawings of the frame and info/ some knowledge what part´s to use with 170-177 rear.. as I have also build salsa beargrease2 2015 from frame up...
    If You are from Europe I highly recomment to use R2bike...

    Cool...I thought you were the engineer but I didn't think your name sounded very Chinese...never heard of R2bike, thanks for the reference.

    So those look like the right rear shock bushings?

    Cheers...thanks again!

    Yep, But You need 2x 1mm (edit it is not 1mm its 0,1mm!) spacer/washer for upper.. It is 22,4mm what You need...you are Fine with 22,2. But I would not worry about this yet, will se what frame looks like, also there can always be some variations between frames. One may need 1-2mm spacers depending tolerances.. And your shock etc. it is a good choise.

    Hi Jukahia,
    it seems that you're the first biker to puchase this frame, so your future feed will be appreciated. Will you build a fat bike or a plus bike?
    I plan to build a 29+ full suspension.

    Greetings from Italy

    Does this frame require a special rear hub in order to play w/ the split pivot dropouts? Or would a standard I9 (12x 177) thru axle hub work?

    What do you think about this shock ?

    This shock, and Rockshox Bluto are on my plan.

    Yep..looks good, Might be a bit too much, but who am I to say...

    Chinese carbon full suspension fat bike-img_0515.jpg

    My plan was to use parts what I already have, but that I forgot ... As I started to plan build.

    Now waiting frame to arrive in three weeks;
    -Bluto rct3 120mm
    -Manitou Swinger SPV 6Way Coil Or RS monarch.. 1000g Or 215g, both new ( Both are from sale... so -70% to -55 % prices.. ) These shocks I have bought to look & test what would be the best option...
    -Xt 11 speed
    -10-42 Sram cassette
    -SRAM Chainset X1 1000 FATBIKE 11sp 30t GXP (In use @salsa)
    -SRAM BSA 100 BB GXP
    -shimano SLX brakes
    -Cane 40 headset
    -Hugo 52 27.5 x 50 wheelset (2240g) & Hodag 3,8" tyres are ordered (mid. Dec. is delivery)
    Both wheelsets ( I now have 26" Hope+Nextie65 set) have same hubs, so I can convert both wheelsets to fit Beargrease2 Or CS001.
    So tyres that I will/can currently use, will be
    Front; Bud, Dillinger 5 (studs) or Hodag 3.8"x 27.5
    Rear; BFL, Dunderbeist, Dillinger 5 (studs) or Hodag 3.8"x 27.5

    Hopefully there will be more 27.5 x "3.8" options... And will se how they fit... My calculations say that these fit...But I know for sure when I have test drive them all.

    Best and cheapest are rarely the same thing

    I'm a fan of the Raceface cinch system, you can get fat specific spindle for the crank and available in a few price points (SL next, turbine, and a lower one I think)
    KMC chain, shimano cassette, RD and shifter of your choice.

    Both wheelsets ( I now have 26" Hope+Nextie65 set) have same hubs, so I can convert both wheelsets to fit Beargrease2 Or CS001.
    So tyres that I will/can currently use, will be
    Front; Bud, Dillinger 5 (studs) or Hodag 3.8"x 27.5
    Rear; BFL, Dunderbeist, Dillinger 5 (studs) or Hodag 3.8"x 27.5

    Hopefully there will be more 27.5 x "3.8" options... And will se how they fit... My calculations say that these fit...But I know for sure when I have test drive them all.
    Curious to see how and when your build comes together!
    Debating one of these frames but wanted to see it done before I jump in. Biggest challenge I think for this frame will be setting up a properly tuned rear shock that works well with whatever front fork your putting on the bike. Bluto would be my first choice but this thing would also rip with a 140mm plus fork. Getting to be a lot of choices....

    Thanks Peter.
    Can you tell us what shock tune you recommend? Or what is the leverage ratio? Thanks!

    Shock Tuning

    Peter, it would be nice to have a graph showing the rate of change of the leverage ratio --- is it rising, falling or flat. Can you get this from your engineer? Whatever the case may be, this bike rides the cusp between Low and Mid Tune. See this helpful PDF:
