skywalker – everyone know’s a manufacturers recommend size for a given height is a very rough guestimate as an aid to get a ball park figure. They’re a starting point as it were.
They are, but they are building the frames and they know who they will fit. A 16″ Five is intended for people from 5’4″ to 5’8″, you at 5’11” are way out of that and fit smack bang in the middle of the 17″/18″ sizing.
In a shop, you always size “safely”, it’s always safer to size a little larger than smaller. I too work in a bike shop.
I have worked in bike shops and as a cycle mechanic through my whole working life. That statement is totally wrong. If between sizes you would sell the customer the smaller bike rather than the large. You can’t make a big bike smaller, but you can make a small bike bigger (longer stem, layback post etc)
You need to consider riding style, rider preferences, terrain amongst many other factors when sizing for a MTB (road is different, you’re only trying to attain maximum padalling efficiency position). With MTB sizing you’re trying your best to juggle compromises.
Riding style doesn’t come into it. If it’s an XC bike it will have a longer ETT, if its a DH bike it will have a shorter ETT. You don’t need to take that into consideration, the manufacturer has already done that for you.
From what i can make out from the OP, their priorities are out of the saddle handling, they felt the 16″ was nimble and chuckale enough, they have BMX roots, so favour a nimble bike. The size charts will be based on in the saddle efficiency and the fact the orange five is marketed as an all day, “do it all” trail bike, so will be sized to be comfy in the saddle.
Again, what he is used to doesn’t make any difference. He could have been sold the wrong size bike before and he will now think its “right” as thats what he is used to, when actually its not.
My gut instinct from doing this as a job is that a 16″ will suit the OPs desirables very well and the fact that a eff tt of 582 really isn’t short in the grand scheme of things.
I disagree, and you would be guilty of doing the above.
Also I feel, this is only my opinion, MTB sizing is too used to the days of 100mm+ stems giving lots of room in the front, so is too hung up on replicating this feeling of “space”. People are used to this “space” so if they don’t have this space in something they try, it doesn’t feel immediately right so don’t give it a chance.
I don’t know where you get this idea. Bikes are now being made with longer ETT’s than before so people can run shorter stems and wider bars.
Look on any manufacturers size charts, I guarantee you will not find one that puts you on a 16″ bike.
