New frame: Longteng RD301-D

[Hillhater]

That internal BB is less than satisfying. If I recalled ( I don't have pic to shown the internal as I already build up the bike) correctly it should be smooth and no wrinkles like that. You might want to show it to Alisa first before you start the build.

Yep I sent email to Alisa. I will share the reply when I get.

It's Fidlock single toolbox(https://www.fidlock.com/consumer/en/twist-single-toolbox/09646-p00002-blk)

I can replace the box to the bidon which support fidlock system.

very nice, thank you.

Got a reply from Alisa, and here is the part;

Confirmed with our production manager , the uneven BB inside surface will not effect the safety of the riding , you don't need to worry about it . 

sooo... I will try to believe her(and the production manager).

I don't remember who it happened to but there was one person who had doubts about the manufacturing quality of the carbon and the salesman told him not to worry when the problem really was dangerous. But for your case, I cannot comment.

Yeah, this's a classic way to say "fuq off." They talk to the manager/engineer/god/Lucifer, and everything turns out to be perfect and in order. "No worries, friend, buy more frames." Quite common for chinese carbon manufactures sellers.
I guess if it concerns you a lot, the most reliable option is to show it to someone who might have some skills to test/diagnose. Or seek help from internet experts here and there (I'm not the one, unfortunately).
Otherwise, build and test yourself. You could find some weak points after assembling.

Hello

I ordered this frame.

Could you please share which T47BB you can recommend ?

Also does anyone know if a Magene P505 crank would fit ? Seems to be a gamble with T47 frames

thanks,

Considering the price, I Choose Praxis T47 – I.B. SHIMANO.
Magene P505 is compatible with Shimano(24mm), so it will work in your case too.

If you have extra money, you can choose change the better bearing(like NTN or ZEN) or you can go Chrisking if you are rich enough.

Because there are several BB brands, find the bb with those terms and choose based on your preference : T47 internal, shimano(24mm).

Thanks for your reply.

Magene website says that T47 is not compatible with their crankset. Have you actually installed one ? Do you have pictures of your build ?
thanks,

I have been trying to understand this in the recent days and the way I understand it is external T47 is fine, internal T47 depends on a frame and is a gamble.

I’ve ordered this frame and am building it up with wheels from Peter here.

Any recommendations on cranks and chain rings? Trying to keep the weight down while also keeping the budget  I am running Shimano 105 11-speed shifters, derailleurs, and brakes. I also picked up a lightweight cassette from Ztto.

Edit: I don’t know if it matters but I’m quite light 70kg/155lbs but can do a 1100w sprint.

How are your builds guys? Any new observations? That picture od the inside of bb area got me concerned... Did anybody got hold of the TanTan (Seraph) variety? How is the storage compartment cover? This is one of the highlights of the frame, making it na alternative to Trek Domane, Argon 18 Krypton, BMC Roadmachine or even Enve Fray.
