Hi, another older mountain biker here, but much older lol , I also have an Izzo Pro Race and before I also had Turner bikes, What is the model of Turner bikes you had?
My last Turner bike was a Flux DW Link, I'm 5'8'' tall and I had medium and small Turner Flux, now the Izzo is medium, but I do notice that the length of the top tube and the reach of the Izzo medium size are shorter than on similar bikes such as Ripley, SB- 120 , Spur , Ranger and Trail 429

I am 5’6” and ride a medium Izzo. I find the cockpit on the short side, but this is a more trail oriented bike than the race bikes I am used to which were also medium, but with 90-100mm stems. Great for climbing with the steep seat tube angle however. But overall this bike is so smooth, balanced handling and stable, it is a joy to ride (for me).

Just to confirm, does the 2022 Core 4 with XO1 mechanical shifting, NOT have a UDH? I see only one comment in this entire thread that mentions this, but omits the year of bike model they're referring to.

Looking at a new-looking '22 Core 4, bone stock other than the tires as an upgrade from a 2012 Trance X1.Yes, I am still rolling on 26" wheels. He's asking $3500 CAD.

Any feedback is welcome, but I'm considering buying this and over forking it with a 150 mm 36, Pike or whatever I can find used for cheap, then shortening the stem to a 35 or 40 mm. The bike is an XL, I'm 184 cm tall. Looks like the shorter stem and longer fork would reduce my reach from ~490 mm to ~465-470mm while picking up the bb~6 mm. Comparable geo to a Jeffsy, which I intend to try for on a clearance next year, if this bike goes well for me. $7100 for the current Flight Attendant model is a steal though...

Budget isn't really an issue, I'd prefer the new GX or XO transmission on something but NEW bikes seem like a very big depreciation loss with diminishing returns.

Thanks, I couldn't and still don't see any information on the offical Izzo website you linked to regarding the type of hanger used on their frames. You can still use a mechanical derailleur with a UDH, right? Mechanical shifting doesn't mean no UDH.

What's the link for specifically?

Best thing to do is reach out to YT directly via customer service on their website.

HI . Normally, bike companies that incorporate UDH hangers in their models immediately highlight it as an example: Ibis, Transition Yeti, Revel, etc. ,and they also release their bikes with Sram Transmission groupsets.

Now, bikes with UDH hanger can use Transmission or mechanical rear derailleur.

Bikes with traditional hanger (according to each brand and model) can use mechanical or previous Sram electronic rear derailleur but not T-Type Transmission.

Surely in a very short time YT Industries will begin to release its different models with UDH hanger.

Another fine point to take into account, in the brands that have changed from the traditional hanger to the UDH, for obvious reasons there was a design change in the rear triangle, well...there are brands that do not allow changing only the rear triangle, that is but they don't even sell it.

So if you want to install a new Sram T Type transmission group, you will have to change the entire frame.

I bought the bike. It looks like a UDH to me, but I can pull it off and confirm with a bike shop... 2022 Core 4 - X01 Mech.

Can anyone confirm from these two photos? It's worth mentioning in this thread if these are UDH bikes since there is mention that they are NOT.

Yes you can use a mechanical derailleur with a UDH. A UDH is just a standardized (SRAM designed and freely licensed) hanger, to which the derailleur is attached. UDH replaces all of those bike-specific hangers that have been used in the past.

To clarify, my question was whether these bikes had a UDH, not whether the UDH is compatible with specific mechanical derailleurs. YT doesn't appear to advertise the UDH as a frameset feature on their website, at least not that I have been able to find.

In search for the answer without seeing the bike, one of few hits on google brought me to this thread on MTBR where a member(s) stated the mechanical iterations of the Izzo do NOT have the UDH.

"A nice update to the Core 4 AXS is that it uses a UDH. Its the only full carbon Izzo that currently uses one"

"No UHD on the '22 Izzo. Mechanical shifting, not Transmission."

Local bike shop says this '22 Core 4 is T-Type transmission compatible.

Update:

The following links show the UDH and Izzo specific derailleur hanger. According to links, Izzo models up to 2021 utilized an Izzo specific hanger and somewhere in 2021 switched to the UDH. Looking at these photos it's clear the hanger on my bike is the proprietary Izzo specific hanger. Oddly, they also list the Jeffsy, Capra and Decoy as using the UDH along with the Izzo, yet my 2022 Izzo has the old hanger that supposedly went away in 2021.

UDH
Izzo Specific RD Hanger

I suppose the bike shop that gave a thumbs up on UDH didn't look close enough. They are similar looking.

My 2023 Izzo has a UDH and it is a mechanical derailleur.

For what it's worth, I ride an XL at 6' with a 40 mm stem and plenty of room for a OneUp 200 mm dropper post. The bike is very comfortable and stable, but when I get bored enough, I plan to switch to a size L frame (not an Izzo...need to try something else for fun) and switch parts over. It's not a one is better or wrong thing, it's just to have more fun on more trails. In my case, there is one local trail system I ride that I find exceedingly tricky on the XL. Very rocky, slow, and technical with tight switchbacks. I want a shorter bike for more fun there. Everywhere else, I enjoy the XL.

So you can slam a 200mm dropper post in an XL? I can't find any concrete numbers on maximum seatpost insertions for the Izzo, and I would like 300mm insertion on an XL. I contacted YT, but it's a Sunday morning, and I'm hoping to order a frame asap. Thank you!

What is the best way to access the inside of a frame downtube? I have to change the brake and shifter hoses and I'm having problems getting them through blue "silencer sponges" inside the downtube. They just pile up while I push hoses through. If I remove the BB, is there a connection to the downtube? Or to rephrase, what is the best way to reroute the hoses in the downtube?

A) I'm running a 210 mm OneUp close to slammed on my XL. No issues.
B) on my 2020 frame, there is an opening between the bottom bracket and the downtube. I was just in there changing the bottom bracket and pulled a loose piece of hose out (I'm not using the shock lockout).

Oh man. After just spending ~3 hours trying to route the dropper post cable and eventually making a wire pulling snake from a 1 m length of copper wire... I'm rooting for you. No answers here, sorry.
