CRF-51 build, the last new frame with external cable routing?

[adam900710]

Noted. I'm more worrying about the stack height and the amount of spacers i'd need to use to have a good fit haha.
Another question: I found the link to the frame on Taobao as well, for 3000 RMB. If i want to have them upgrade to higher tier T800 carbon, as well as including the thru axle and headset, i have to message them for that and then pay a price >3000 RMB right?
I'm pretty sure i read somewhere that you've upgraded to T800, unless i'm hallucinating.

The 3000 RMB price is already upgraded to T800. Note the T800 in the screenshot. Of course it's better to confirm before that.
I just paid extra 200 RMB for the customization, 100 RMB extra for front and rear thru-axles (not recommended though), another 50 for the headset bearing.

Considering the axles and bearings are not that good, I prefer to prepare your own axles and bearings.

The axles I brought separately have the following spec:
Front: 123mm total length, P1.5 16mm thread length.
Rear: 168mm total length, P1.5 19mm thread length.

Which is cheaper and lighter than the ones from the factory, with proper washers to avoid wearing the carbon (the factory one has no washer).
This is the link where I brought the axles: https://item.taobao.com/item.htm?id=707446848461

Bearing can be easily brought from Neco, it's pretty common standard, upper bearing is 42mm OD, 28.6mm ID, lower bearing is 52mm OD, 39.8mm ID.

Thank you so much for the info regarding the axle haha. I just found out today there's like at least 10 different thru axle size, so this is preferable since i can order it along with the frame at the same time, not having to order the axle after i get the frame.

If you are looking for Thru Axle I highly recommend these https://it.aliexpress.com/item/1005005612065745.html, staying away from the carbon ones hahaha you should also find them in your size

And you may also be surprised by the seat post collar ID, it's not the common 31.8mm one, but a 30mm one.

I even tried the 29.8mm one from WolfTooth, it's just a little too tight to fit. The real measured side is around 30.4mm. Just in case if you want to find a 3rd party collar.

Thanks for the heads up mate. Yea the geometry chart also said it's 30mm. It's easy to missed it. So i assume it's not included with the frame when you bought it?

Included, but again I ditched the original seat post and collar.

The original seat post has an offset of 25mm IIRC, switched to a 0 offset one.

The original collar looks pretty chunky, but works as expected. Just switched to a lighter one (but still looks chunky).

Btw, what would you say is the good option for BSA BB?
Originally, i was searching for BB86 frame as i THINK i like BB86, since i'm 100% sure i'd be using the ZTTO threadfit stuff, or climb up to BBInfinite for that "free spin" thing. But from my experience with my older bike, that free spin thing is harder to get with BSA. I mean i know BSA is reliable, it's less prone to squeaking, but still. If push comes to shove, i can still live with BSA with this style of frame haha.

Not a huge fan of free spinning BBs, as under load resistance should be more important. But if you really want that, there are tons of ceramic BBs no matter if it's PF86/BSA.

My personal BB choice is always Shimano first if you're using 24mm axles. It's always available, cheap, reliable.
Otherwise I go with SENICX for their steel bearing BBs for DUB. (30mm axles are and should be dead now)
