I used one of these in my VB-R099 - Quite a tight fit (Needed to tap it with a rubber mallet to get it in) but it works very well:

https://dedaelementi.com/expander-70

If I remember rightly, it was lighter than the stock plug, despite being considerably longer.

I was looking to get one of the Deda 70mm plugs but didn't think they would fit as they're advertised as being for 23.5mm to 25mm internal diameter, whereas I measured my 168 internal diameter and it measured at exactly 21.5mm.

I ended up going for the standard Specialized Carbon Compression Plug (https://www.bike-components.de/en/Specialized/Headset-Expander-for-Carbon-Steerer-Tubes-p78544/?o=69400069-black-1-1-8-&delivery_country=NL

I switched to this one. Works a lot better, no slipping issues.

My suggestion, check to see if the stem is not becoming loose and knocking the expander out. Are you using the one piece handlebar, are the screws a two piece thing? Use some threadlock on them

Also there are some longer expanders from Neco in Aliexpress that are quite good.

Anyone knows the THREADING of the thru axles front and rear?


Planning to get some J&L thru axles from ebay with an expecting weight of 46g together, which would be a saving of around <40g if I'm not mistaken to the stock ones.

==> Just unsure which size to select.

My plan is to preorder all parts until hopefully soon my frame arrives, but who knows when that will be.

I have a question for those who have installed mechanical shifters. How or where did you put the adjuster for the derailleur?

I'm using full mechanical shifting (Shimano 105/Ultegra) and brakes (Juin Tech GT-Fs) but am not sure what you mean about the adjuster for the derailleur?

Are you referring to the front or rear derailleur? The only adjuster I can think of is the barrel adjuster on the rear derailleur however on my 105 this is part of the derailleur itself?

Some older front derailleurs required a barrel adjuster in the cable. I think it would be difficult/impossible to use these on a fully integrated frame. Best to get a derailleur with the adjuster built in, like with the latest generation of Shimano 105.

Thanks for the answers. I meant the front one. I know until now only those who have this adjuster in the line.
If it has newer with an adjuster on the derailleur itself then my question is settled.

The Shimano 105 R7000, or Ultegra R8000 is what you need (if you're running a Shimano groupset). Just make sure to get the braze on version and not the clamp on  :)

Start with the bad. I'm doing a big gamble on these cranks. They are hollow arms and 7075 spindle. I figured if my 63kg body brakes them no one should ever use these.  The inside chainring is yellow not color changing.

Onto the fun part. The crankset is 650 gram and the bling rings.  Bike is now 7.38kg 16.25lbs.

Are those the crank arms from Goldix? I believe the fundamental problem lies in both the axle size and material. If they're 29mm then alloy should be fine. If they're 24mm then only steel should be used.

Yep they are the goldix 24mm crankarms.  Ordered before tracevelo video was posted. Before his video I was concerned with the hollow cranks.  He just added another layer to be cautious about.

Once I get replacement crankarms, if these suck, or they fail I'll post up.  I have 7000 crankarms so I'm can swap at any point.

This forum never disappoints. So 78g vs around 40g with the alternatives i.e. 38g saved for 50USD… seems a bit crazy but I’m not yet decided.

Also, Chris told me my frame would get painted this week, let’s see whether that’s gonna happen.

has anyone bought a frame that included decals? how did the paint job/decal quality end up being and how much it ended up costing? My dengfu was painted but the paint isnt of good quality as its pretty easy to chip away at the paint, as i have a handful of chips in the paint.
