i have a pair of cheapo oem rockshox xc30 on my hardtail, they're ok, but very little tunability in them which is fair enough considering the price, my F/S bike came std with Fox 32 FIT/CTD, which again are ok but not perfect out of the box, i'm having the same issues most are, set them up for supple low speed bump absorption and they blow through on high speed and vice versa, but i can live with them until i upgrade to the FIT4 option.
I'm happy with what i use overall because i have a realistic expectation of what you get with suspension out of the box, it's naive to think that buying suspension will magically work for _your_ needs straight up, bike geometry, rider style, rider weight, terrain, rider skill and speed etc. all effect how the suspension performs, it's adjustable and tuneable for a reason. The manufacturer (whoever it may be) will develop a product that they believe will suit the majority of it's customers within the tuning range of the internals, if you're lucky enough to be one of those happy days, if not and you want better performance you have to pay for changes.
All parts supplied as oem are built down to a price, they have a contract to supply X amount of units that will work within certain parameters, profit margin is the focus here but at least the gear _is_ tuneable if the end user wants to adjust it, and i don't mind FOX limiting who works on their product, there's much more to customer service than just supplying parts and tools, there's only a very small percentage of owners that have the knowledge and understanding to correctly service their suspension, they're protecting their reputation from ham fisted tinkerers who fuck it up then blame the product.
It's also worth noting that most who buy bikes with adjustable suspension have no clue how the adjusters effect what the suspension does let alone how to change it to make it better for them, so manufacturers dumb it down to a price point and for those who want to fine tune it it's there.
My bike came with FOX forks, i didn't make the decision to go out and buy them, but if i did, your assumption that choosing a product you dislike makes me a mongoloid is offensive, there's 1000's of brands to cater for everyones preferences, you don't like FOX? fine, i'm curious to your motivation for starting a thread purely to rubbish a brand and the customers who like/use it?
