Notched vs. Micro Notched Snail Cams

Are there any advantages for the notched snail cams (e.g. Rockman) over the micro notched ones (e.g. Trialtech)? I imagine that the micro notches get damaged more easily. Having notched screws on my frame, would I even need notched snail cams?

Sounds like you're confused about what the notches are. They are small indents in the cams around the outside edge to help hold them in place when you adjust your wheel. When you use smooth cams they have a tendency to slip back round whereas the notched cams don't. The only difference between standard and micro notched is with the micro ones you get more adjustment options as the small notches kind of give you halfway adjustments compared to standard ones.

Finding it hard to explain without saying notches 1,000,000 times!

Ah right, it was the mention of notched screws which confused me and still does???

There's a right way and a wrong way of fitting them to protect them from damage but I'm not sure what they are. If the notches have been flattened just take a small file and cut some more in yourself (Y)

I'm not. I was just wondering whether the big notches are more resistant to damage. Right now I have micro notched snail cams and after only one ride, the micro notches got damaged already, meaning they are flat now.

Yes, they are. They are bigger and have more meat to them, meaning the screw doesn't deform and flatten them as much.

Well, my bolts have notches as well.

Would it be better to take those then even though the offer less adjustability?

If you are having problems with micro notched, then yes. Worth a shot.

Well, I dunno if I am having problems with the micro notches. Here's the situation:

- mounted new Echo TR Freewheel + Trialtech cog on the rear

- did all the steps shown in the Tarty Snail Cam video

- tightened the Echo TR hub bolts to 12Nm

- rode up and down the street

After that the chain had a slag and I had to do it over. I had a look at the snail cams and on the drive side the notches were flattened out. Later, after having tightened the chain again, I rode some more and the chain got slag again. I put a mark on my frame that shows that the rear wheel hasn't moved but the slag got bigger nonetheless. The chain is a 3x ridden KMC Z610.

Same problem I had with a Because frame and TR hub. The washers on the bolts are smooth so don't hold the wheel tightly enough in the dropout. You'd be better with some toothed washers to grip the dropout properly, that's what solved my problem!

I was told (Tarty) that aluminum washers only help a little and that I should get steel serrated washers. Couldn't I just use these under my echo washers?

Does it matter how I mount these? Meaning if I mount them to click downwards or upwards to tighten the chain.

Never spotted that those ones were alu as the ones I got ages back from them were the Onza ones and were steel

No. My question to Tarty was about some Trialtech washers but having a look at the description of the Onzas it says that only the bolts are steel and the washers aluminum. If that's really the case (and I doubt that the description is wrong) would these do as well?

I had massive notches on my rockman one. I couldn't tension the chain properly as it would get too tight before going to the next notch if that makes sense?

Filed them down and works perfectly.

I prefer my jaf snail cams though, mini notches are so good, shame I can't get the other one off the wheel so I'm having to use one rockman one jaf haha.

They'd be worth a try. What I was saying is I was sent the Onza ones from Tarty which were steel bolts and steel washers but since then Onza must have changed them to aluminium.

Well, I asked at Tarty what steel washers they recommend. They may have some old Onza ones lying around. :) If not, I'll just get some of those serrated washers like these. They should work as well if I'm not mistaken.

I just got a reply from Tarty saying, that they don't stock any steel washers. So my question is, can I use the linked serrated washers? It should work as it's not the stronger clamping force of the steel washers rather than the form. Right?

Sorry for the conflict of info, but I guess Flipp hasn't seen them yet - we had some in the Monty stuff we got recently. They aren't on the site yet though, and I can't say how long it'll be.

The best cams if you want good reliability are the Trialtech steel.

The spiky washers you posted a pic of, they just crush unfortunately.

So far so good. Have mounted the Try All serrated washers + a Trialtech HD cam* and it seems to hold. Will have to test it though.

Nico.

*Holy f*** that is a nice snail cam. The JAF I had before are a piece of sh*** compared to the Trialtech.
