Arrjay - IP/FM/MC-036 Build Thread

[arrjay]

Thanks in no small part to this very forum, I've got a IP/FM/MC-036 build in the works.  Parts are still coming in, and some parts are migrating over from my current ride (and therefore can't be pulled until the end of the build - lest I risk being without a mountain bike in the interim).

As mentioned in a separate post, I have a chiner road bike, so I went with what I knew and used the same chendor to purchase this frame.  It arrived the other day, light, well-packaged, looking sweet, and ready to be built up. 

Wheels were off of Pinkbike, e13 hubs laced WTB KOM rims.  Front axle converted to 20mm TA.  Rear axle set at 142x12, but that may have to change because though I thought I was getting the frame with the convertible 135 -> 142 spacing, I measured it and it looks to be 135...  anyone have any insight into how the spacing is converted on these models? I could remove one side of the dropouts but that wouldn't get me 7mm more of spacing, and I can't remove both without losing the derailleur hanger I think...?

Went budget on the rear shock and got a deal on a Rockshox Monarch R.  This may be upgraded down the line for a model with at least lockout.

Went over budget and got an RWC needle bearing (just one) to replace the lower bushing.

New Praxis BB to convert PF30 to SRAM (so I can use my current crankset)

New old stock Rockshox Reba RLT from pinkbike - 20mm TA, 120mm travel

The legacy parts co-opted from my current Niner Air9 (alloy hardtail):
Niner carbon bar at 720mm
Deore XT hydraulic brakes/cables
SRAM L-handed rear shifter (forget model)
SRAM XX crankset
Wolftooth front ring, wide-narrow for 1x set up (36t?)
Shimano cassette (11-34?)
Racing Ralph Snakeskin Evo tires (about 5mo of use, so these will be replaced in the near future)
Crank bros candy pedals
KS dropper post OR Shimano PRO carbon post
Bontrager saddle

Here's a frame pic to get things started, more as things progressed.

Sweet.. Another build thread. I'm not sure if I have some type of disease or something but I could literally look at chiner build threads all day. lol.

Which chendor did you go with and how much did it cost, if you don't mind me asking?

Always good to see another detailed build, particularly the IP-036.

I suffer from the same affliction.  Fortunately or unfortunately, the prescription is to build your own - and this is a classic case of treating the symptoms and not the disease, so one is never truly satiated.

I purchased through Miracle/I-Can.  The 135mm frame was quoted at $560, but since they didn't have it stocked they (supposedly) upgraded me to the 135/142 convertible dropout for the same price.  However, I can't really tell how to convert yet and the spacing seems to be 135...
[this price was not including shipping which seems to be pretty standard from all the chendors to use EMS and charge $70-85 per order]

I also got a spare derailleur hanger for by chinese carbon road bike.  And in hindsight, wish I would have also just ordered a wheelset.

Parts and tools have been trickling in.  A few bumps in the road have been worked out (steerer tube on original fork too short so picked up a new one, wheelset hubs converted to the appropriate spacing no problem with end caps), but the current hurdle is in regards to the bottom bracket and I'm seeking (your) expert input.

I installed a Praxis Conversion BB that is set up for MTB spacing at 72mm and will allow me to use my current SRAM XX crankset.  However, the issue is that there unequal gaps on either side extending beyond the BB shell (2mm Drive side; 5mm Non-Drive side)

Is it possible that the BB is only 68mm in width?  Anyone else have similar issues?

(I've contacted Praxis, who has been very responsive, but short of a repeat install or problem with the BB shell width we're at a loss...)

[Carbon_Dude]

The bottom bracket width of my IP-036 is 68mm.

[arrjay]

Well, shoot...

I assumed 73mm width because I thought the 68mm width was the road standard and 73mm was the MTB standard.

Thanks for the response, guess this BB won't work for me.

[Carbon_Dude]

In comparison, the bottom bracket width of my IP-057 is 73mm.

 I used spacers with my GXP BB on my IP-036 but the spacers were not needed on my IP-057.

Here is the technical drawing of the IP-036:


It shows the BB width of 68mm.
