It's Marcin from AbsoluteBlack.
Spiderless version indeed does not have narrow/wide tooth, so it requires short/medium clutch cage in order to work properly in light riding. But even then for some it may not be enough in very demanding terrain.
My 104bcd chainrings do have narrow/wide profiles and it is impossible to drop a chain almost. What DanW wrote here is the issue with KMC chain. My chainrings does not work with KMC chains and thus problems with mud. Every other chain works, just not KMC as they are out of spec and have to tight links (wrong dimension). KMC got back to me as they found out on my website i don't recommend them so i guess they will soon make a running chain to fix the issue.
I will have in 5-6 weeks also Spiderless version with narrow/wide profile. So if someone is really unhappy with the current performance of regular spiderless chainring please get back to me via email (firstname.lastname@example.org
). But please notice that i wrote very precisely on my website that when riding in demanding conditions you WILL need to use chain catcher of some sort on the top.
Most customers of the spiderless solution are singlespeeders and Enduro/DH guys. first ones does use anything and second ones always use a full chain catcher anyway "just in case" as for them is scary to ride without anything. So for these people i have build non narrow/wide chainrings as they don't need it.
New chainrings are coming soon so stay tuned.
Only aware now that KMC chains are not suitable for the spiderless chain ring. I have only just rebuilt my Scott Spark up in preperation for this coming seasons racing and have only done 2 training rides so far. I put on a KMC X10EL chain with a Sram X0 type 2 short cage and its flawless. First ride was mucky & bumpy with no problems at all.
