Re: VeloBuild VB-TT-023 I am new to building bikes, and I am looking for a BB for the VB TT 023. The measurements on the website says 86.5. I am doing a sram build and can only find a 85.5mm T47 Sram dub BB. Can I go with that?

Thank you!

Can someone advice on the bottom brackets they used? Almost all parts for my build are ready except the bottom bracket because I cannot find a SRAM DUB bb for the TT-023 frame shell width of 86.5mm. I am running a SRAM Force AXS 1x setup with 165mm DUB Force D2 crankset and Red 1x 50T. Will the SRAM DUB Road T47 bb do the job or I need the Road Wide version? Thanks.

NikkoPh is using t47 dub bottom bracket https://chinertown.com/index.php/topic,5156.msg64449.html#msg64449

The guy in this video used the Sram Dub BSA 68/73 BB, he wrote it in the comments "youtube.com/watch?v=PtYLbQ-97fM"

Could someone please post the measurement between the two basebar towers? Center screw to center screw.
I asked chris from VB. Basebar 400 / 420 / 440mm -> 81,5 / 101,50 / 120,50mm

I had another look at transferring my Shimano set up and it looks like it will be a pain (as it is now!) Especially keeping the junction box internal.  So I will probably go down the SRAM two pairs of blips route with the RideRever (Triva hydraulic TT) brakes. Anyone any feedback on those?

I’m running the RideRever Trivia’s and 2 pairs of blips. Works a-ok for me, no complaints really. Don’t have a huge amount of time outdoors logged on them but they seem to do their job.
Will be doing Lanzarote IM on it in 6 weeks time so they will really get put through their paces their.

Can you post photos of how you routed the hydraulic brake cables?

Sadly not, as you wouldn't see anything. Its entirely internally routed. Through the basebar and than through the back of the hole in the clamping area and through the stem

Can you post photos of how you routed the hydraulic brake cables? My set of riderever triva brakes is still on its way from Japan and I am currently using cable-actuated brakes. And it is not a good experience so far. I have changed the cables twice and the braking power is still not satisfactory. I have routed the brake cables through the top holes of the stem and brought them inside the stock base bar holes on the lower side. It looks ugly and not so aerodynamic. These cable-actuated cables seem to be so hard to bend and go through the stem as hidden/internal routed cables. I am running 1x sram force with wireless blips so the only cables I have are the brake cables.

This is two brakes mecanical cables and one rear derauler mecanical cable.

Re: VeloBuild VB-TT-023 My tt-023 is built and road ready. If anyone would like close-ups of any bits let me know.

The brake lines feed through the bars straight into the headset and through the frame to come out near where the calliper are mounted.
The cables for the gears if not using remote shifters are a little tricky but run down the bars through the arm pads, come out the back under where the elbows would sit then route into the headset through the 2 eye holes. I have electronic remote shifters so didn't run these.

I had my LBS ran the lines as it is a very tight fit (brake lines only, I didn't have the tools). From what they said you need to tighten the levers in first then pull the cables through to the callipers, mounting the front end as you go. The reverse of how it would normally be done. Also the headset top tightens front to back. Otherwise the bull horns don't sit tight enough to hold riders weight.

I have only done 40km on the bike, before having to take time off due to an unrelated injury. Compared to my other TT bike it feels similar maybe a bit more twitchy, but I had high cross winds and the 80 front wheel was just a big sail pushing me all over the place. About to fit a 50 front, hopefully solves some of the twitchy riding.
