Re: Opinions on Elves frames

I didn't buy that bike, but...

A teammate of mine is considering buying one and inquired about it in September. At that time, the tire width was 25C, and we were told it would be 28C by the end of the year. The bikes were VANYAR disc and FALATH disc.

Just FYI.

Maybe a 32C when the mithril versions are released.

Edit - To add something that may actually be useful.

I like the Vanyar geometry. I ride a Giant ML frame now, comfortable enough, but probably a touch on the big side. Their 2XL seems comparable in size to a medium Propel or Aeroad.  I'd consider a 2XL 54 Disc Vanyar, if it could fit 28C, and, if I could get matte black to knock a couple hundred off the price, and the silly name off the frame.

Re: TanTan TT-X21 frame Hi All,

Happy New Year!

My new TT-X21 frame arrived this morning.

I first contacted Lisa on 11/25, ordered the frame on 11/29, the frame shipped on 12/16, and arrived today, 01/04. I'm sure it would have arrived faster if shipping hadn't been in the middle of the Holiday Season.  Overall, I'd give TanTan a solid B for quality of service. There were a ton of details that needed to be clarified, I wasn't sure how the frame would be shipped until I saw the EMS waybill, and even then, Lisa told me not to expect the frame until the end of January after it got hung up in Tianjin. In retrospect, no issues that were TanTan's fault and all minor stuff that didn't affect the actual transaction.

The build quality looks good, but it's my first carbon frame. Here are some pre-build pics. If you see anything I should be concerned about, please, if at all possible, let me know.

Thanks!

Re: TanTan TT-X21 frame Hi All,

My X21 build is almost done. It's mostly new components but I'm waiting on things like correct sized bolts for brakes. I have used shifters with an overtightened bleed port cover that I had to pretty much destroy to remove. Its holding the brake fluid, but ordered a replacement. I also have a loose headset that I can't seem to tighten down with the supplied compressor assembly.  Might have to go to the LBS for that.

Re: Price & availability check... My TanTan X21 was in  stock and shipped EMS back in mid December. No complaints about tracking or shipping speed. The frame with shipping and all the odd bits I ordered just to feel better about compatibility was under $700 USD.

I am expecting delivery of spare handlebar spacers soon.
What height do you cut the fork at relative to the handlebars?

Just about every set of instructions I saw on cutting the steerer says, once you determine how many spacers you will use, to mark the tube at top surface of the stem, then cut 3 mm below that mark to give the top cap enough space to tighten the headset. In the case of the X21, of course, you mark the steerer tube at the top surface of the integrated handlebars.

With the TanTan top cap and compression plug I got with my headset, though, I actually had to use a 5mm spacer above the handlebar to have enough space to tighten down the headset after I cut the tube. The bottom surface of the top cap bulges into the space above the top of the steerer tube and didn't allow me to tighten down the headset enough with just a 3mm space I had after I cut the steerer.

So, I guess it kinda depends on what compression plug and top cap you are going to use. Apologies if that doesn't answer your question.

Re: Zrace RX - Does it play well with Shimano derailleurs? Agreed, I'm so ready to pull the trigger, but luckily they are currently out of stock for 50/36 chainsets, giving me some time to try to get some feedback on the Zrace.

Hi all,

Have you had experience with play on your frame? If yes how did you resolve it?

I had an issue with the headset, as it didn’t matter how tight I made it,  the sort of half ring that stays in between the steerer tube and the top bearing seemed a fraction to small, causing the play that become extremely noticeable when I assembled the bike and used the front brake to rock the bike back and forth.

Cheers

Yes, this was an issue from day one. I went to my lbs and the tech set me up with a set of head set spacers. They are super thin, .25mm each. They sit on top of the lock ring, the half ring, that sits on top of your bearings. A stack of three worked for me, but I bought an FSA ACR headset awhile back, hoping to fix the problem that way. 

To make a long painful story short, I could tighten down the headset, but then the steering would bind, with the fork rubbing up against the head tube at the bottome, and the top cover rubbing up against the head tube at the top. I tried an FSA ACR headset, but that didn't solve the issue completely, but it did help. I ended up using one of the fatter ACR bearings at the bottom, and the fatter TanTan bearing at the top, along with the fatter FSA Lock Ring at the top, but I couldn't completely eliminate the play withing binding up the steering.

These spacers worked like a charm. No headset play at all and butter smooth steering. Yuo'll have to cut a notch in the spacers for the cables, but that's pretty simple, and you'll just have to play with the amount of spacers it takes. They come in different thicknesses.

Good luck!

Re: TanTan TT-X21 frame You "could" tighten it more. The instructions for the FSA top cap I was using says you can go up to 5 Nm, but you're supposed to tighten "until proper bearing load is achieved". The instructions say 6-9 Nm for the compression plug itself. <edit: do not overtighten your compression plug, even if it is slipping! I never got close to 9 Nm, and decided to try a different one rather than risk cracking my steer tube.>

My experience with my frame has been that if I had to use more torque than 2, maybe 3, definitely not more than 4 Nm, then it was because the bearings weren't loading correctly. The biggest issue I had early on was that the TanTan compression plug kept slipping, no matter how much I tightened the plug itself, so the top cap was never able to tighten down the headset regardless of the torque used on the top cap. When I switched to the FSA plug, it held much better, and that's when I started having issues with binding up the steering. The binding would happen at around 1 or 2 Nm on the top cap.

Seems like it is sorted out now, and it really doesn't take much torque on the top cap to load up the bearings properly.

Re: Difference in quality between ~600$ and ~1200$ frames? Quality wise, I think the Tantan TT X21 frame I purchased for just north of 500 USD is pretty good. Im going to just sau its identical to the VB r099. But, it does have it's issues that showed up during the build. Nothing a first time bike  builder like myself couldnt eventually handle, but I can't imagine running into the same problems with a frame from a major name brand. I could be wrong, but I don't know that $500 more is going to mean you won't have the same issues.

I guess my question would be, what are you hoping to get for $500 more? I wanted a carbon framed aero road bike I could build myself, something faster and snappier than the aluminum framed endurance bike Id been riding, and well within my modest budget. Mission accomplished.

Thanks !

Who is your contact person and email at TanTan ?
I'm looking to build a couple of hardtails, and could start working with them.

You can try Lisa, she's who I work/worked with. She's still answering emails and filling orders for me. I have no complaints.
