Climbing The Factor is a good climbing bike, and strikes up an interesting proposition. If you've got a remote lockout, then it would be great to really utilize it and have a very very soft
open mode, for ultimate traction, a middle mode for descending, and then the lock out for road section. However, I never really felt I could get the grip or tracking from the bike that I wanted. It's efficient, but I would argue too much so.
The claimed anti-squat of around 90% at sag for the lowest gears just didn't add up for me and it raises an interesting point - anti-squat values are just often harder to pin down and quantify than is ideal. The height of the rider's center of gravity, plus other factors, can easily throw it out. Before looking into it, I would have thought this bike had values of over 100%. There is an important note though - this is compared to other bikes that are limited by the same inconsistencies. So maybe the Factor numbers are correct, and other brands are a little out. Either way, I would have liked a lower value and better tracking for technical climbs.
For those that do want a firmer feeling XC bike, this does do a great job at giving that; I'm just not sure how that fits in with it comfortable marathon bike. It feels racier than that. It's a bike for turning a big gear at pace and using its speed and drive to get over rougher sections, rather than cruising and managing to seek out grip.
That then bleeds into compliance. It was hard to say exactly, but it felt like the 1450g Black Inc Twenty Seven wheels were a little too stiff for me. On bigger hits or chunkier terrain, it felt like there was enough flex in the frame to generate some comfort but on higher frequency bumps on seated traverses or fire roads, even when not pedaling, I felt like it could do more to cope with small bumps and stop the rider from feeling so rattled. Like I said, I can't say for certain, but that would be might first point of call if I was looking at dialing in the spec for some more comfort.
The bike, when up to speed, does do a good job of holding its momentum through corners and switchbacks, no doubt thanks to that low front end. Leaning into turns while climbing, and cranking hard is a gratifying experience on any XC bike, but the Factor goes forward with such purpose it makes it particularly enjoyable. The 60 mm stem and 760 mm far felt good to me, too, and felt low without being uncomfortable or unstable.
Pinkbike need to stop substituting their own prefered parts & review every bike as it arrives from the manufacturer
And then,the other 99% of the people who will be buying this bike will be riding it on little more than gravel roads,that's just how it is.
People like Pidcock who can ride a bike fast uphill and downhill are very rare, and it seems none of them are on here.
If you run said tyres with low pressures you know at least one area where you can improve your riding.
Quit trying to be non committed and caring of the manufacturer!
“I'm not sure this is ideal for either cable or steerer in the long run.”
You should say “this is dangerous”, because it is dangerous
In relation to pressure, it’s not as cut and shut as saying - but racers run less. Some do. Some also run inserts, and static droppers or thicker tyres. I stand by my pressures, and we need to review bikes that are setup best for the people reviewing them - not some conceptual person that may or may not exist.
on my xc rig, I could run 28psi on similar tires and also force them to have problems with sidewall. But if I don't think about it, I just set off and do the type of ride that these bikes are built for, matching my riding lines and energy expenditure to the time and distance I expect to be on the bike, anything over 22/21 for me is more pressure than necessary.
What you're likely forgetting is that XC racers - even pros - don't usually throw a bike into corners during a race like you enjoy doing, because it's a waste of energy and no faster. These guys and women are usually running less suspension sag than you'd consider ideal, and the tires act as a low-amplitude filter, taking the edge off the chatter while allowing the suspension to be firm for climbing and accelerating. Their setups are ideal for their use case.
FWIW, I'm on 2.2" Cross King/Race King tires with Vittoria XC inserts at 18 psi. I can get away with even less on a 2.4" Aspen. I only weigh 150, but raced pro XC as well as BMX and DH in the past. I just don't ride my XC race bike like I ride a trail bike. If I ran softer suspension and firmer tires, it would be less efficient for hard accelerations and out-of-saddle climbing.
I'd wager that those tires at 22 psi would be a totally different ride, but you make a good point that a rider more concerned with riding it like a downcountry or light trail bike would be better served with suspension components with less compression damping, or a different bike altogether.
As another datapoint, I owned a new Blur before my current Exie - the low antisquat value Blur really needed the lockout for hard accelerations or climbing out of the saddle. I only touch the remote lockout on the Exie for the road ride to the local trails.
Like Henry said, the suspension kinematics do not change appreciably until near end of stroke regardless of if you are running 20mm of sag out of 100mm or 20mm out of 115mm, IF the eye to eye does not change. However, the impact energy that the suspension is capable of absorbing does change. This can be represented by the integral of suspension reaction force over the length of its stroke, giving the reaction work done by the suspension. Longer suspension travel of a given 'firmness' is capable of absorbing more energy.
Ummm.. Yeah, they're faster than us. They're also like 2/3 the weight of an average person of the same height.
We could all run lower tire/suspension pressures if we were built like marathon runners. Few grown adults are though unless we're talking high level athletes.
I've been riding since the early 1990's though, so I learned to pick a line before suspension and with very little suspension. 16-17psi is faster, but there are some risks to it. I'd probably agree with most of these replies that 21-23 is the sweet spot. 28 seems absurd to me though, unless you are trying to use the bike for something it's not designed for. But that makes me wonder why you'd pick that bike in the first place.
1. If Henry was riding like a normal human he could probably run 21-23psi which is alot higher than Nino's 16/17 and it would also handle great compared to 28psi.
2. I'd like to see more of the trails he's riding in the review. I have an uneducated opinion that the Pinkbike reviewers are definitely fast but they are also downhill goons that smash rocks and corners on trails that are not equivalent to a normal UCI XC track.
I'd bet a UCI pro XC rider could make it down the hills Henry is riding some % faster than him. Then Henry could jump on that riders bike and immediately destroy a tire going slower.
I run low 20's on my Enduro bike, and 25-30 on my trail bike also. My trail bike has 27mm rims though and the rears like to burp out pressure if I ride aggressively over rocks and roots.
XC racers are probably under their listed weight in the middle of the season when they're training hard. So, it's hard to say very accurately.
People are forgetting that in an XC race you slaughter yourself up the hills and then go down the hill slower than you would in non-race conditions. Even more so if you are a good descender because you deliberately try to overtake on the climb so you aren't slowed down by the dirt roadies on the descent. So you don't need to worry about pinch flats as much.
And then there's grip. Can I climb steep fireroads faster with lower tire pressure? Absolutely! Because I can put more power down without spinning out.
You say : "Increasing the suspension pressure by 10-20% is a totally valid way of reducing the effective travel."
The thing is that this will also decrease your SAG and completely ruins the way how the bike feels versus how it was designed to feel. Its always better to play with spacers or even replace the shock for different tuning than to reduce SAG to single-digit values.
The Usain Bolt comparison makes sense if and only if the Enduro or DH rider is at the low bodyfat % of a world-class track sprinter. Some of the pros? Sure. But the average rider who says "I'm heavier because of all the extra muscle I have" is also carrying 10-30 extra lbs of fat along with that muscle.
Anyway, there are too many variables at play to tell anyone (without understanding the context of their rides) what psi they should be riding. If tires are squirming, burping, or flatting, you're left only to suspension adjustments for comfort gains. I assume Henry made efforts on tires and suspension before straight labeling this bike as harsh.
run a 28psi on xc bike , with more reason you feel harsh and not comfortable, is not the bike fault is your fault. haha
I own a Blur and the traction is has is crazy, when racing on blind trails it's super nice to have the confidence that you will clean a section of technical uphill every time because of it.
Now its 630 with 475 reach large or 650 with 495 reach XL.
Pick your size off your fingertip to fingertip wingspan, not your height. You'll be much happier.
My height is 73 3/4" and my wingspan is 72 3/4". Thats why I'm moving back to larges now that bikes have gotten bigger.
I ride the SID 35 and SIDluxe, you won't need any adapters for the shockpump and it is just ripping while being super fast on the uphills and longer adventures.
Also the wheels are indeed to stiff if your not doing races like unbound or something, it was a massive change in downhill performance switching these.
For me it is my go to bike and altough it is insanely expensive (like everything else nowadays) im really impressed what factor did on there first try on an MTB Frame.
Just for the fact of "roadies doing mtb" I would have liked to see the comparison between the lando and the cervelo fs
Cheers!
Respectfully disagree. Compare the weights of the wolftooth at 160mm travel (slightly over the fox in weight) and then the 9point8 dropper (weighs just less than the fox transfer sl) at the same travel, comparing 150mm travel on both.
The bottom line is every company claims to have the lightest dropper. It isn't until you dig into the specs sheet that you realize which marketing materials you believed.
A couple jabs of the brake normally fixes it. Happens after heavy braking in the rough.

On the tracking - I think for a lot of people having a stable base is good. I came off a very plsuh 120mm bike from the past few seasons and love that I barely need lockout save for sealed or smooth climbs. I also opt away from the stock wheels for most races as they weight about 300g over claimed, and I prefer a lower profile and wider rim paired with 2.4" Aspen/Rekion Race (plus a liner in the back). And not at 28psi but I'm not going to bother critiquing what another rider uses and trusts!
I'd love Factor to improve the routing options (yes, wireless is real, but not for brakes as of yet) and I'd look at a slightly longer reach, and size specific stays. Given they make their own bikes, at this pricing that should be possible. I really like that it is a racey ride - it suits their market and as a racer I really like the pedal response especially on steep and technical climbs - there is no wallowing around. I'll be interested to see if they do more in the MTB space, and what a V2 may look like.

"For those that do want a firmer feeling XC bike, this does do a great job at giving that; I'm just not sure how that fits in with it comfortable marathon bike."
Nice semi-colon usage ;-)
Also, that dumb little spar from the top tube to the seat tube is proof of crap design. Straight tubing, 34.9 post diameter, maximum dropper insertion are good to have on XC bikes too.
That said the fact that it's profile is pretty similar to other bikes is a function of where we're at right now in bike design, there is a proven formula for what works.
