I'm in the process of ordering a 268 frame but would appreciate some advice on the headset & stem. At risk of repeating an old question - has anyone successfully used a SL7 stem/spacers/transition kit on this frame? I understand it's possible to use a FSA no.69 headset with any stem of choice, but would prefer an integrated look with the SL7 stem.
   
In the 168-frame thread there's been some discussion about 3D-printed transition pieces for the Allez Sprint. Unless I misunderstand, this round design will not match the 268 frame, and will leave a gap where the original transition piece is? Has anyone gone down this road?

On a similar note, is there a consensus on the quality and durability of the included headset bearings? Would it be advisable to replace them with FSA bearings for peace of mind, regardless of the stem question above?

Thanks!

I am building my bike and the is a little bit of space between headset bearing/ compression ring and what insaw on a youtube video from patty that he uses somekind of other spacers.

Maybe original spacers for an sl7.

The spacers that i got from velobuild look cool and where painted in same color as my frame.
But seems to doesnt really fit well.

I am going to overthink this and maybe replace these item for original Specialized ones. As alse it is recommended to buy a bigger expander for the steering.

The velobuild is to short and not that good.

I send Patty a meesage on youtube but insee him sometimes react on this page aswell.

Maybe this is also a part of an answer on youre quistion.

Trying to catch up on all my messages. As good practice with budget frames, I always use expander plugs from the brand called "Neco" which can be found on Amazon for like $13-$20. Length large, aluminium or carbon top cap. Not the lightest plug ever but no slippage. Especially if you plan to run spacers above the stem

I found that my steerer internal diameter is only approximately Ø22,3-22,6mm - too small for the Deda 70mm expander to fit (requiring >23,5mm). Seems like most readily available alternatives require >23-23,5mm. Anyone else have experience with this? Perhaps the steerer has an inconsistent thickness, will figure out as I cut it down.
