DT 240 engagement
Still trying to figure this out-
trying to decide between DT240s or King hub.
The biggest question is regarding the engagement for DT240s with the star ratchet upgrade.
Does anyone know the degree of engagement at the crank arm or hub? I had seen someone post the degrees based on the ratchets divided into 360, but this does not seem to hold true in the real world (at least not with my Hopes which should be 10degrees but are more like 2-3)
How is the DT compared to a Hope? I find there is a little lag in the Hope engagement, but nothing that effects my riding. I wouldn't want anything that engages slower, and that is ultimately what I am trying to find out with the 240s
thanks,
DT

DT is 18 point stock, 36 point with the upgrade. Not sure what your seeing with your Hope hubs but they are 24 point so it is 15 degrees at the hub. Of course this will vary at the pedals depending on what gear combination your in.
Hope Pro 2 is 24pt, their SS hub has 48pt.
The DT with upgrade is 36pt. It's pretty obvious that 36 points of engagement around a circle gives you 10 degrees between contact points. It's math...

yup, math is easy if you know the right numbers. I knew my hope was less than 15 which it is since it is the SS hub.
probably not much differencee in feel between that and DT's 36pt

Yea, I really wish hope would use 6 pawls in their SS hub instead of 4. They get to 48pt by using the same number of dents as their standard hubs, but they offset 2 of the pawls so that only 2 of the 4 are hooked up at a time. I think it would be better if they used 3 and 3 instead of 2. Still, they are a great hub.
I don't think you'd feel any real world difference between the hubs. Be aware, some people have reported slipping of the DT ratchets when using the 36pt setup on a SS.

There have been numerous reports, and first hand knowledge, that the 36 POE upgrade is weaker than the stock 18 point.
I had a co-worker upgrade to the 36 POE on his DT wheels. He broke a bunch of pawls after a few rides. He called DT Swiss. DT Swiss told him the 18 POE kit is stronger than the 36 POE. They warrantied the 36 POE kit, and he sold it. Went back to the 18 POE.

ugh. i give up. I broke pawls on my hope, then cracked the shell in half. I don't want an unreliable hub. I think King is the way to go. I was just trying to find something that spun better ; )

FWIW my DT240 with 36pt upgrade has only ever slipped when I had too much grease or used too sticky of a grease. The enagement rings need to be able to freely slide away from each other through the channels in the hub and freehub so that they properly disengage. Others have reported the same too. I know slipping is not the same as breaking the teeth on these (no pawls btw, just two toothed rings), but in my opinion the root cause is the samefrdfandc said:There have been numerous reports, and first hand knowledge, that the 36 POE upgrade is weaker than the stock 18 point.

Hadley has really good engagement, reliable internals, and spins welldtheo said:ugh. i give up. I broke pawls on my hope, then cracked the shell in half. I don't want an unreliable hub. I think King is the way to go. I was just trying to find something that spun better ; )
Hadley
True.
I was trying to drop the weight as much as possible on this wheel. I think the 240 is about 260g, King is 310g and Hadley 350-400g?? Not sure if those include the bolts or not (SS hubs)
I am leaning towards Hadley on a Flow for my fully.

Mine have never slipped, just chipped. 2 sets. 1st set with synthetic oil, 2nd set has started chipping with dt lube.boomn said:FWIW my DT240 with 36pt upgrade has only ever slipped when I had too much grease or used too sticky of a grease.
