TanTan TT-X38 Build

[MrLee]

as someone who ride this frame like a tribike (saddle so far fwd) with clipon aerobars on reach extenders, this frame is as close as it gets to a tri bike posi, at least as close almost equal my tt912. as your saddle go higher, the saddle isnt going further back (thus your seattube angle increases, like old plasma)
so i get it why Seb Kienle used a modded ScottFoil as tri bike (he's sponsored by Scott, but he still had access for top tier lightest Plasma if he wanted).
downside, missing toptube boss-mount for bento box, or any internal storage for tools.

if anyone on a budget for tri bike build, this frame is worth a consideration as its almost half(but dont include tri cockpit) of tt912 or other tri frame price. but you need to go full internal cabling, n i suggest go axs for least cable goin thru the top bearing

I happened to come across this frame while searching for a triatlon bike. How much van you get the saddle above the BB in size 56? That isn’t entirely clear to me

I have heard that this frame can take 36mm wide tires (WAM). Is this true?

I have heard that this frame can take 36mm wide tires that is after getting ballooned by the rim. Is this true?

I run Schwalbe pro one 34mm tyres on a 21mm internal rim and it fits. 34 WAM - about 3-5mm room. at the fork its the closest (maybe even just 2mm on one point). So 36mm might be a tad too big depending on final shape of the tyre and stiffness of the wheel (flexing).
