Chinese Carbon MTB > 29+ & 27+
Ican P8 full suspension build
Bos:
I forgot the photo of my current steed before I post the new frame.
Bos:
So Here's my new frame! I must say, much burlier in real life. The P9 must be awesome, because this alone was - WOW.
Sure, There are small imperfections on here that are probably not there on a Santacruz or something, but at just 100g heavier than a Tallboy and 1/3rd of the price, who's smiling?!
I am struggling to find the boost converting kit for my rear 12x142mm hub. I just rebuilt these so I'm not that keen to break them up again right now since I will most probably get a few other things I need to replace during the build.
So, I put my wheel in the dropouts and threaded the axel through.(pic attached) the gaps on the side of the wheel axel were seriously 2mm a side. I guess it could have been 3+6 which =6mm. The "standards police" will probably flame me for saying this but what the heck, It took no effort at all to flex the frame back to 142mm. Which I know... you lose the benefits of Boost, you might be cross threading it by 0.5degrees, your chain line will be out by 0.5 deg(I checked) But for the moment until I get new hubs and a new wheelset built up, how bad can it be?
R_Pierce:
Its stressing the carbon and will only get worse when you ride it. Yes, they flex. But they are designed to support load at 148mm spec. I wouldnt personally risk that myself without knowing any long term effects. But with that said, to each their own 8)

Have you considered something like this:

Never tried it myself, but maybe a good solution?
Bos:
I'm having the spacers made as we speak guys. Was more wondering how something so subtle can really damage a part thats designed to take pretty major forces and that normal riding will exert forces at far more critical angles.
What was far more important was when I popped one of the pivot bolts out. Being a Chinerello virgin the little voice inside my head said.. just check the pivots for grease before you try ride it. To be honest. I guess one will never know exactly what the carbon layup looks like inside the frame, but one area where one can kind of see that you're not buying that Tallboy is the pivots. The holes where carbon were wrapped around bushes(plugs for pivot holes) were done pretty roughly. Its all covered up pretty nicely but there are a couple of voids in pretty high stress places on some of the seatstay pivots on my frame.
There's some photos below but not of the voids. Took me about 3 hours to do all pivots. Should have done it before the bike was assembled but I had a local bike shop assemble it to save time.
Something else I noticed. The pivot near the rear axel had a steel bolt which at 30g a pop is some unnecessary weight to be adding so close to the suspended end of the bike. Maybe room for improvement in the future. I see they hollowed them out to try save weight. I bet it can be made from high grade Ali. All my bikes Iv'e ever had had Ali bolts at all pivots. But this is a minor. Just thought I'd share.
