Which adjustable cam wheel?

[merlin's S4]

I've found both of these hall sender friendly adjustable cam wheels. Both are of similar cost but is there any reason why one would be better than the other?

I use this one and it works fine for me...


happy new year btw

I would steer away from the dahl back item. Its made buy CNC something i cant remember the name sorry!

[Masterblaster]

[Masterblaster]

Hi,

have you had alook on that woodruff key?? i will modify mine aka chef, thats for sure..

which cam wheel would you prefer if you need a new one?

[lind4hl]

cannot answer that, since this is the only one i have had my hands on..

I also use the dahlback one and not had any issues though only covered 2k miles. The wood ruff key does look a little iffy but infinitely stronger that the original that has been known to snap off when tightening.

You couldn't snap the dahlback one.

Just my 2p...

I have the same gear in 25mm.

The woodruff key failed whilst turning the engine by hand

Its a pretty poor bit of steel/mild steel

Was this with a loose front bolt? snapped many a standard one doing the same thing.

I did and i will post it tomorrow..

The wood ruff key looks a bit iffy but cant imagine how it could snap where as with the standard one that looks very vulnerable..
