Dang, I've been looking around for a while and haven't seen these.

I thought the only budget options were going to be riderever triva or mechanical brakes with either mechanical disc or cable actuated hydros.

If you go by Trek's recommended sizing, the L version is suited for riders from 175 to 186 cm, while the XL frame is recommended for 186 to 198 cm.

Velobuild doesn't offer an XL size on their website.

I can't speak for Tobi, but personally, I wouldn't go for an L frame at that height. I'm not sure exactly what his fit looks like or how he managed to feel comfortable on that frame. Bike fitting is a complex discipline — different bodies can have very different proportions even at the same height.

In my case, there's the added concern about the basebar slipping at the stem clamp. When I found a good forward position, the basebar rotated, so I got scared and moved the extensions back a bit.

In that sense, I'd like to have more freedom to move forward without worrying about it, but you work with what you've got. It works for me as it is now.

Right, If they offered an XL I'd probably order one. From Tobi's pictures there is a TON of seat post and a pretty good amound of spacers but the saddle is centered and no extra reach on the cockpit. As far as the stem clamp slipping did you get the newest version of it? Still think I'll be going with winow for the larger size and putting on a pretty standard stem to avoid slippage.

It's crazy how variable peoples fits are... Tobi is 194cm and says the fit is great, muringuets is 12cm shorter and feels like the reach is too short??? Interested to hear some elaboration on this.

Dunno why I keep seeing these "new" "TT" frames come out with 73 deg STA... the geometry is like a road bike, should work just fine with drop bars and a standard road position.

I would say the TT groups would behave similarly to their respective road counterparts. Lots of issues with ERX road (ERX-TT looks like it would be equivalent to the ERX V3 but who knows with all the different SKUS and random updates they do). Some users have no issues, others are plagued. It seems like part replacement/availability is not there and a huge lack of warranty/customer service. Seems like very few places even list it and the prices vary a lot like 750-1200USD on aliexpress.

Wheeltop is probably in the same boat, I've seen a couple reviews and they have a weird delay when shifting from the brake levers due to the single button waiting on double presses for FD shift. The 2-3 youtube reviews are positive but I think they got them sent for review and probably don't show any hassle setting it up.

It is not cheap enough to justify it over something like sram rival/force with blips which are completely wireless and WORK and either riderever trivia or mechanical brakes (or mechanically actuated hyrdos). There are tons of sales on rival/force D2 and the used market is pretty good. Both of the chinese groups are disc only which removes them from being an option for someone picking up a cheap used rim brake frame.

I would either just stick with the stock split risers, or get an entirely different setup like the second pic.

I think the QuickPro TT:ONE is currently the lightest TT bike with UDH to come out from China. I could easily be wrong though, would be happy to find something else myself.

and as i said, same mold as the ican tt017

If price is no object the qickpro tt:one i think is UDH and is probably one of the lighter frames. It is the same mold as the ican TT017 which i think is much cheaper but maybe harder to come across.

Spend time in any Reddit Bike Fitter thread and you'll see that not even two professional fitters can agree. So I chuckle when folks speak in absolute terms about another rider's fit. Perhaps they are plenty comfortable and are still achieving the results they're looking for.

From my reading around I've found that to be the case, people can't agree. Some fitters will try to get things to be in numerical ranges vs just trying to get the person comfortable on the bike.

Hi everyone, I'd like to order a frame—size L. I'm 195 cm tall; do you think that will fit? Also, are extra spacers included for the cockpit?
What have your experiences with the bike been like?

If you have a longer torso the reach will probably be a problem area for you.

Has anyone purchased one of these yet?

I'm very intrigued by this frame. I think it might jump ahead of the VB TT023 for me, because of how nice the cockpit is looking!

You can buy the cockpit standalone from BXT.

the width still should matter with relation to the tire width you want to run. The enve ses disc is "optimized for a 27/28mm tire" so the external is going to be in the 30mm ballpark (it isn't even listed on their site).

anyone aware of similar frames available in XL or XXL (~61cm) frame sizes?

in this price bracket the only larger frames are the winow tt119 and the seraph tt912. They will get you more reach and stack to get you into the 58-61 range. If you have the money to spend, hongfu/avenger tm7 and the quickpro TR:one have larger frames.

These brands need to quit doing so much with these tt frames. Give us a pretty basic but sleek looking frame with modern TT geometry. Throw in an adjustable front end with a stem/integrated base bar that isn't crap and I'm sure more people would be interested.

Hi guys thanks for everybodys information here, I've learned a lot. I'm looking at a build, it will be my first bike build so any feedback welcome. I noticed most in here have built up with a 1x chainring, wonder if there's any reason for this or just preference? Anything wrong with going 2x? What I'm thinking below (prices AUD):

Frame   Velobuild TT023                   1433
Wheels   10Plus 60mm                   500
Groupset   Ltwoo ERX TT                   1300
Crankset   "Magene PES 515 52-36   537
Chain   KMC X12                           50
Casette   Shimano 11-30                   120
Tyres   F1 Supersport                   120
Saddle   Ryet   TT 3D                        150
Rotors   Zrace 140/160                   25
Bottom Bracket   Token 24I                   50

2x is just more expensive I think. Also I was looking into erx tt, it looks decent but not worth the price with the fear of reliability issues.
