Ok, I have the Chaser Caliper Adapters (front/rear) and the Chaser UDH hanger.

Anyone know how long the rear brake Calliper bolts are on the ER One for Shimano 30 or 35mm?

The carbon is 25 mm thick. According to SRAM you need 5-7 mm for the brakes (so 30-32 mm in total). I use 32 mm for the Red Caliper.

Thanks man — I've confirmed it's 35 mm for Shimano.
It's been hard work trying to find  that out!

I picked up the groupset from the post office yesterday from Anarncee store on Aliexpress
I've got some chaser parts as well: rotor lockrings (including a cassette lockring) and the Ultra rotors.

Have a Bikone T47-68 bottom Bracket

I also have the Sixwheel UDH direct mount, shifter clamps and screws, thru-axles, front caliper mount, pivot bolt and caliper screws, bleeding bolt, and hose bolts. Not relevant to this build, but I also grabbed a computer mount for my SL8. Sixweel 11-34T Cassette 148g.

I've got an S-Parts kit on order for the DA brakes.

I sold two sets of wheels during the week and have now ordered a 65/65 mm wheelset with 25 mm internal width from Zen, built with THR Industries RX hubs (21/24). With mount them with RideNow TPU tubes and 28mm Maxxis High Road SL Tyres already have these.

DFS Carbon, Carbon Crank 165mm with 24mm Titanium Axles that's 286gram.
Not sure on PM yet and chainrings yet. Also have not ordered a saddle contemplating RYET ultimate    same as one on my X68 or there 3D copy of the Bjorn Sekta saddle same as on my SL8
Pedal Xpedo Thrust 8 Ti

Would you mind sharing a link to the Chaser parts you have used ?

I'm trying to confirm which UDH fits 100%

Thanks

The UDH1TH is for Shimano direct mount and UDH2TH for all other (SRAM, Campagnolo, ...).

Thank you 

Have you had good experiences with Chaser? I'm also looking for a direct mount hanger.

Apparently a DM hanger is supplied or can be supplied with the frame if you ask.  Never tried there parts. but I have a silver DM hanger and Pivot bolt that maybe going spare as I also have a Sixweel UDH hanger and pivot bolt being shipped so if your in the UK dm me if interested.

No, sorry, I'm from Germany. I bought a direct mount hanger from XLC. Unfortunately, they only come in black.

Here we talk about the ER:One....

I can't recall receiving as many private messages to review a frameset more than this one. The wait is over finally.

Why is it not built yet?

Looking forward to it
