That's awesome! i did design and print a rear bento box for my propel a couple of years ago. it worked great until it disintegrated in a flat second. My advice: carbon fiber cloth or (cheaper) fiberglass cloth to reinforce everything (or pre preg to make your life easier, presumably). My box failed in the middle at some random layer line, which retrospectively, makes sense. It was more of an experiment than anything, i was phasing out the use of that bike already, so i didn't print a new one and didn't get around ordering cloth.

i like the ghetto TT front end rig a lot, well done!

Yeah given the failure rate on the er9/erx, i'd wait a good 2 years after they RELEASE the triathlon version to put it on a race day bike. race bikes have to work on race day, enough things can go wrong without worrying about whether your group will decide to shift that day.
Eventually though, if they do get their act together, it will indeed be great. Should also open the doors to the "order a full custom bike from china straight to your door" market. Everything is in Xiamen, once their groups work, should be very doable to get someone to build you a bike, or at least most of it, the way Trek bikes arrive in shops, for eg (plenty of videos of Trek unboxing on YT).

Well, especially as a triathlet i would stay away from ltwoo on my racebike..not many races i participate and loads of training...thrown away if you have a faulty whatever....
i mean, this is so typical chinese...they ignore the problems, give you a hard time when something is defective , do not change it fast and after loosing trust in the brand due to lacking reliability, they try to enter triathlon.....?

The 411/412 are decent hubs. I use them on my gravel and on my roadbike. Have done 1000's of kms with them. They need some maintenance and replacement of the bearings from time to time (I use cheap Ali bearings) but I've not have anything fail on me.
Replacement parts and freehubs are cheap and easy to find.

A total noob question: What kind of software are you using to design stuff like this? Some sort of CAD-software? Is it free/open source? I’d be interested to design a storage box to mount inbetween the water bottles in the frame triangle on my TT-X38.

I'm really excited for the TT brake and shifters LTWOO had on display at the Shanghai bike show. Maybe I'll be able to build an electric shifting tri bike under 8k aud

Component Deals & Selection / Re: Evosid version of 5DEV cranks
« Last post by Confused on May 13, 2024, 06:56:34 PM »
The Evosids are 585g for the 170mm (only size) and the 5Devs are 610g for the 165mm. Both without chainring.

A few others for comparison:
Rotor Kapic alloy crankset - 545g - with chainring.
Descendant Carbon Crankset - 555g - with chainring

Road Bike Frames, Wheels & Components / 2024 Tan Tan TT-X39 - A Rim Brake SL7 with 32mm Tire Clearance!?
« Last post by waltthizzney on May 13, 2024, 05:05:03 PM »
I was searching for a traditional compact handlebar for a practically new 2012 Tarmac SL3 I recently purchased and was browsing the tan tan site and came across this.

For reference I have owned a FM066 through tan tan, it was a good bike, probably most ridden Chinese open mould ever, but the BSA BB shell delaminated from the frame after around 40,000km, not sure if it was issue with bike or salt getting in the frame from riding in Ontario Canada but that bike owned me nothing considering it was $500 and rode way better than my Scott foil previously

I then bought a LTK118 that has been a great race bike, although it rides twitchy and seems a little sketchy on the downhills

So here we have the Tan Tan TT-X39. Is this the bike everyone has been asking for? Rim Brake with huge tire clearance?

It looks identical to the SL7, and I have heard of a rim brake SL7 being produced via a Chinese website but google translate only works so well, so this might actually be the mould.

The most incredible part of this frame is the stated 32mm tire clearance. I am not sure if that is even possible without direct mount rim brakes
