Small Chain Ring - 6Al-4V titanium and full contact tooth profile. The same low weight as aluminum, with INCREDIBLE durability! Both 8 & 9 speed compatible.
Middle Chain Ring - 6Al-4V titanium and full contact tooth profile. The same low weight as aluminum, with INCREDIBLE durability! Both 8 & 9 speed compatible. Our middle chainrings have shift pins and special tooth profiles for smoother and faster shifting.
Perfect Teeth - Cycle Dynamics produces it's rings by "gear cutting" which is the most accurate method of shaping the teeth. Accurately shaped teeth give a larger contact area than other brands of Ti ring, this gives the longest possible wear, by spreading the load across the greatest number of teeth and most edge surface of each tooth. All this wear reduction means that you save money compared to replacing your Aluminium rings four times. a year.
Firstly, Titanium chainrings aren't about weight loss. Most of you reading this will know that Titanium is heavier than Aluminium. This doesn't mean that Ti Chainrings are heavy, in fact Cycle Dynamics rings simply need less material and are therefore a fraction lighter than XT Aluminium rings. The real benefit is in the rate of wear of the chainring teeth.
Chain Suck - An Aluminium ring has to stand a lot of abuse. The better ones can take a really hard effort, cheap rings can "indent" on the first standing hard push and be subject to chain suck from day one. But the real Al killer is mud.
The grinding paste we all ride in for eight tenths of the year (in Britain) eats away at one side of each chainring tooth, caing a hook which will eventually result in a nasty case of chain suck. When you're at your most tired, when you're putting in your hardest effort, those little hooks will help pull the chain up around the back of your granny or middle ring.
The result is a sudden jamming of your drive train. End of climb. When it bites bad you won't be able to ride up a hill in that ring at all. This isn't a rare event, it's a time served certainty. The only way to avoid it is to replace your Aluminium chainrings as soon as they show signs of wear (pointy, narrow teeth, wide gaps).
This is an expensive job, with very fast wear rates in the Winter and the dreaded chain suck around the corner, the answer has to lie with harder wearing rings. Steel and Titanium rings wear at about the same rate (Ti has the edge) but Steel is a heavy alternative, especially for a middle and granny combination.
Titanium rings will last around four times as long as Aluminium.
There are many chainsuck preventing "gizmos" on the market and one or two fairly effective home cures, involving giant zip ties. The trouble is that worn chainrings accelerate wear on your chain and this passes that wear rate to your cassette.
The Steel cassette rings should give long wear but a prematurely worn chain will kill your cassette in a far shorter time. Once the cassette is badly worn the chain will slip suddenly and unpredictably during occasional hard efforts.
This can cause badly banged knees and shins, ouch. In order to ensure a smooth shift under load the Cycle Dynamics Ti Chainrings have four pins and shaped teeth which assist the chain as it climbs from the granny to the middle ring. Without these changing gear would be a clunky affair.
