Thanks, quite interesting read. But it also doesn't really explain that huge price difference between these 165 Euro Tec shocks and let's say Öhlins shocks for 950 Euro. Or YSS, it is still factor 3-4.
I am still somewhat puzzled. 150 British pounds. For this the Chinese company making them needs to earn, well, at least something. Then add the transport costs, import tax and the labour cost of Tec reworking them. How on earth can they have better quality than the stock shocks without any side effect. There must a a drawback somewhere. Durability ?
I just re-read my post and you're right. I did a lousy job of answering the question. I guess I was too worried about appearing to bash any particular brand of shock. I'm still not bashing. However, Amazon has pages of rear shocks which look identical to all the others from the outside. Some for $45 a pair, USD. A few for $24. Most in the $75 range, RETAIL.
And if you and I order a pallet of them we can get a discount. Then we can inspect them. Bin the ones that are defective or get a credit for them.
It is the guts, what is or isn't inside them that drives the price. A non-adjustable, single internal chamber with a single plate with holes in it (valve) is only intended to counteract the spring from bouncing out of control. Add in a second plate on top of the first with a screw and now you can rotate (click) one plate so that the holes no longer line up. That overlap somewhat restricts the oil flow both up and down because the hole openings are effectively smaller. You will see that given various names. Unified, parallel, combined compression dampening adjustment. A new price point.
It continues on from there with additional internal chambers and bi-pass tubes (some made from stainless) and another set of valves to control the flow in independent directions (up / down) that is what it takes to gain rebound dampening adjustments. All that is fitting inside the same carcass. Now lets add in high speed rebound and high speed compression dampening and bi-pass and adjustment vales for each. Just to say out loud, the high and low speeds are not about the speed you are traveling along the road. They address the difference between rounded mound in the road and the sharp edge of a pothole. That part of the system is even smaller and more precise. Typically that happens at the beginning of the circuit, but not always. Least we forget that every adjustment we can turn needs to resist the pressure from the inside and the dirt from the outside. By the time we reach this part of universe, "sticktion" matters so we get hard coated, extra smoothed main shafts.
Even the rubber in the mounting grommets are a higher spec because, after all, that is the first point of contact between the swingarm and the frame.
I referenced the Racing Bros website not because I'm advocating for them as a choice but because it is informative even at the opening animation. They also have download user manuals and they make an advanced twin shock product. As you know we increasingly live in a monoshock world. Heck, I even considered (and rejected) the idea of converting my 650 to a single-sided shock.
So I hope this very generalized explanation of the price discrepancies helps. Looks can be deceiving. And don't get me started on boob implants
