Echo titanium


peggysue

Recommended Posts

Just wanted people's opinions on the freewheel and the rear screw on sprocket . Is titanium more likely to crack ? The freewheels centre is titanium and the whole of the rear sprocket too .

Anyone own either and broke them /problems ?

Cheers

My Echo Ti freewheel sounds like it has less engagements and is very quiet, doubt I'd pay £130 for one, mine came on the bike.

The Ti freewheel we checked was 79dBA, the steel one was 81dBA. They both had 108 clicks. If yours sounds like it has fewer engagement points it might be worth actually counting it to check (volume ≠ amount of engagements) and see if there's some damage in there.

What's the best way to open them up? As I think it'd benefit from a service.

easy enough to undo the lockring, but the bearings are not fun at all..........tiny and loose bearings everywhere when you take it apart. they're a twat to put back together, getting the bearings back into the non-lockring side was the least amount of fun i've had this year.

I work in a bikeshop so I've done stuff like it before, it helps if you put a tiny bit of grease around the bearing race to help them stick in place.

Grease in a freewheel is fine, I used grease when I reassembled my Echo SL/Ti hybrid freewheel (SL silver outer drive ring, Ti lockring and body); just blasted it with degreaser after and lube it up as normal. No issues at all.

The rear cogs are fine, I've had one for a total of about 18 months with no issues. The Ti freewheels that I have seen fail, have all failed with the drive sprocket cracking or shattering; the only thing I can think is that because it's still steel like the SL's drive ring, it must be the gold coating they give the Ti's compared to the silver coating the SL's get. All the Ti drive rings i've seen have been corroded with heaving spotting. The corrosion could be the cause of the weakness?

The gold coating is titanium nitride just a tuff coating

The corrrosion wont cause them to fracture. Stress and fatigue
