I am 5'10, should I go for the 16" or 18"?
Spent all night searching on here, general consensus is I am right between sizes, so if I want something playful its the 16", if I want something a little more racey then the 18"…..
Looking to bang on a RS rev fork and build it up for general trail centre abuse with the odd longer ride out.
Lots of very nice looking builds on here, but need a little reassurance on the sizing before I treat myself.Posted 8 years agoLittleTonesMember
I'm an inch and a half taller than you and plumped for the 18". You're right – you're right in between sizes, it all depends on what sort of ride you want. Judging by your comments, I really think you need to try one out for size. Not helpful in itself but realistic… Sorry………..Posted 8 years agoconvertSubscriber
As above – it depends on past history. I'm an inch taller than you but with long legs for my height so my "cockpit" needs will be about the same. My previous history is all road bikes and a xc orientated Scott strike pro. I have an 18inch (ti) with a 70mm stem and to start with it felt like a toy bike I was so upright. Got used to it now but I'm slowly building up another bike for more xc/ bridleway bashing duties and that will have a much longer cockpit for a more stretched feel.
Edit – the effective toptube length difference is only 1/2" so in terms of fit that next to nothing and a size up or down in stem will sort it. There is an inch and a bit in standover though, although both are enormous by old skool standards (as a cyclo cross rider, its positively luxury!), so I guess if you have shorter or longer legs for your height that should be the deciding factor.Posted 8 years agobillyboySubscriber
I'm 5' 11" or 6' (can't make up my mind) and I have an 18" Ti and 18" steel 456, and with a 70 stem they are a good/reasonable fit. I run a straight post and can leave 10mm of rail clear at the back of a Flite Titanium saddle….. if I run a gobi saddle that has a significantly longer distance from end of rail to end of saddle then I have to jam the clamp to the back end of the saddle rail. I quite like running longer stems…90mm or 100mm… especially if I'm using 25.4 bars because it makes things less twitchy (maybe my imagination but with oversize bars I think shorter stems work better and feel more secure..less nervous and twitchy). If I do run a 90 stem on these 18" 456s then the saddle has to be rammed right foreward as far as it will go for me to get a set up where I can still get out over the back wheel for steep descents without lowering the saddle. I'm not a fan of perpetual saddle lowering stops and I'm not going to get an adjustable post until someone produces a decent one!
I've not tried but I reckon I would fit OK on a 16" 456 if I used a 90/100 stem and straight post, and definately ok with a 20mm layback post. I've measured the Thomson post I've got on the 18" and I have got enough length to allow for the extra 2" and still be an inch or so above the Minimum Insert marker.
Ramble, ramble, ramble……..
If I were you I'd go for the 16".
I think the 18" will be too big for you.Posted 8 years ago
OP, I decided to help you so I went out into the wilds of snowy-stuff and hp_source kindly let me have a go on his 16" 456.
IMO- you are definitely a 16" candidate. Im 6ft1 and found the length spot on. Even with an inch of seatpost left before the max-mark I still had my leg straight on the pedal as well. Spot on. Ta hp_source 😀

I'm 5'10 with 33" inside leg and went for the 18 with 60mm stem"
As above there is half an inch in the top tube so very little that can't be solved with a stem change.
The biggest difference is the amount of post, if you have long legs get the 18" and if you have short legs get the 16"Posted 8 years agoHairychestedMember
I am 5'7" and ride:Posted 8 years ago
– 16"456SS albeit in the 69er mode now,
– 12.5" Gary Fisher rigid 26" wheels,
– small Heckler,
– 17.5" Scott Octane full-sus (officially my wife's),
– 16" Marin Wool Fridge rigid,
– 46cms Puch roadbike SS'ed.
I also had a medium size Prophet which I found too tall, 17.5" Trek Y3 – lovely, 16" Rocky Mountain Hammer – too short reach.
I've tried many different stems and seem to be happy with 70mm off road and 90mm commuting in town. Wide bars but not over 700mm.schnullelieberMember
I'm 5ft10 and ride a 16 inch 456, in-line seat post, 90mm stem (should probably shorten this a tad). I have a 31 inch inside leg. I use it as more of a fun bike than a racy bike and wouldn't want to go up to an 18 inch.
In comparison I also ride a 17 inch Kona explosif (1999, 100mm stem more racy setup) and a medium Enduro (2005, 70mm stem, playbike).
On the 456 I do need a lot of seat post for the ups.Posted 8 years agob rMember
Ps. WHY DO PEOPLE WITH FRONT WHEEL DRIVE CARS INSIST ON DRIVING IN SNOW/BAD CONDITIONS?
As opposed to what, rear-wheel drive – surely you mean why do people who can't drive go out in bad conditions?
Luckily we've a Landie, or more correctly my wife has one, which is very useful as my 535i can stay parked up. Its quite amazing what 4-wheel drive (and a computer) can achieve.Posted 8 years ago
b r, conditions were worsening yesterday and I saw alot of cars spinning their wheels in a vain attempt to get somewhere. Mine is also 4×4 and even then I treated the accelerator gently along with the steering and brakes. One lad slid into a kerb inbetween Mossley and Stalybridge and when I mean slid he swapped ends- he must have been doing close to 30 with the road whited-out.Posted 8 years agohp_sourceMember
glad the ride yesterday made your mind up Hora, there were some right idiots out there, I saw another accident on my way back home too… plonkers.
16" seems to suit most people, and like other people have said, pay £150ish for the frame, and it it doesn't suit there's plenty people out there that'll bite your hand off for it at not a lot less.Posted 8 years ago
