Giant Reign Advanced Pro 29 0 | First Ride Review

by 3

James Vincent has been to Canada to ride the new Giant Reign Advanced Pro 29. Read on to see what he thought…


As new bike launches go, this one has been pretty special. Giant pulled out all the stops until there were no more stops to pull, then found some new stops, and pulled those out as well. All to introduce the new Giant Reign 29.

We’ve been wined and dined in a remote alpine lodge, treated to helicopter uplifts and ridden some absolutely incredibly trails with the most spectacular views out here in Revelstoke, BC. ‘But what’s it all for?’ I hear you ask. Well, all this fuss has been over Giant’s new enduro race bike, the updated Giant Reign, for which the headline is that it’ll be rolling on 29in wheels for 2020.

It’s not the most surprising piece of news, mainly because most enduro race bikes these days are also rocking 29in wheels, and seeing as racing is all about going as fast as possible and 29in wheels roll quicker, it’s kind of a no brainer. Except that Giant quietly (quietly? Ed) turned its back on larger wheels a few years back, in spite of having been an early adopter of the trend, so this actually is a pretty big deal. In today’s fickle environment, for the world’s largest bike manufacturer to make such a U-turn takes guts, and I for one applaud them for it. The big question is, does the Reign 29 live up to the hype?

The Bike

The Giant Reign has been around for 15 years now, as the burliest and longest travel bike in the Giant range that you could sit on and pedal to the top of a hill. In the past it’s had roughly 6in (150mm) of travel, delivered through Giant’s Maestro suspension platform, and over time it’s grown from 26in wheels way back when, to its more recent incarnation with 27.5in wheels.

The previous Reign was designed for hardcore trail riding on rowdy terrain, enduro racing, and pretty much anything that doesn’t warrant wheeling the DH bike out of the garage. And this new, larger wheeled model is no different in its aspirations. It’s been developed to meet the demands of Giant Factory Off-Road Team enduro racers who need a fast, efficient and confidence-inspiring bike. And if racing isn’t your thing but you still regularly seek out gnarly off-piste trails and enjoy travelling as fast as possible, then the Reign is the bike for you.

I’ve had the pleasure of riding the flagship Reign Advanced Pro 29 0 that retails for £7,499 and is suitably decked out with a parts list that wouldn’t be out of place at an Enduro World Series start line. Let’s dive in…

Frame

At the heart of the Giant Reign Advanced Pro 29 0, is an all new Advanced-grade composite frame (full carbon mainframe, swingarm and rocker link), and an updated version of Giants Maestro suspension platform that offers 146mm of travel. The frame is a sculpted and flowing affair, reinforced with a huge top tube/head tube/down tube junction, and similarly oversized bottom bracket area for maximum stiffness in all the right places.

It’s a very clean looking frame, with all the cables running internally through the downtube, popping out just in front of and above the bottom bracket area – there’s no danger of a rock strike induced sliced brake hose here! There’s also bolt on rubber downtube protector for any rocks that do get through, and thanks to the compact nature of the suspension layout there’s space within the main frame for a full size waterbottle.

In spite of the short chainstays, there’s clearance for a 2.5” tyre out back and although the bike will accept something bigger, Giant can’t officially designate this, as otherwise the frame wouldn’t comply with the relevant ISO standards that call for a minimum 6mm of clearance. All of this brings the frame weight to 2380g (including shock mounting hardware), while a medium sized full bike hits the scales at an impressive 13.1kg (that’s 28.9lb in old money).

Reign Advanced Geometry & Sizing

The shift to larger wheels means the geometry of the new Giant Reign 29 isn’t hugely comparable to the old model, but it is significantly longer in reach (493mm, size large) and thusly wheelbase (1258mm). The head angle is a pretty slack 65° and the seat angle is an upright 76.8° – both comfortably in the ballpark for a modern enduro bike, if not quite as extreme as some boutique manufacturers.

The common complaint of 29ers is that they’re big, unwieldy beasts that don’t like turning corners, so Giant has kept things super compact out back with 439mm chainstays – just a 4mm increase over the outgoing smaller wheeled model. Working within the constraints of the Maestro suspension meant that it wasn’t possible to make them any shorter without compromising travel or tyre clearance.

BB drop is 30mm, which adds to the centred feel within the bike, and aids stability. The headtube is relatively short at 110mm, and although I can understand the logic of this (it’s easier to add spacers if you need them, than it is to take a hacksaw to your headtube), it does make the front of the bike look a little odd when the bars are raised to the right height.

The same goes for the low standover and seat tube – there’s room for a 170mm dropper, but Giant has opted to spec a 150mm dropper on the large. On the one hand this is great because it allows shorter riders to size up for more reach if they want, but on the flip side I found myself lowering the seat post within the frame to get the saddle out of the way before dropping into steeper trails.

Suspension

Utilizing the new Trunnion shock mount, the rear suspension has had a major update too – through three phases of prototypes in conjunction with racers Adam Craig and Josh Carlson, the designers settled on 146mm of travel, which is on the low side for an enduro bred race bike, but Giant has prioritised high quality suspension over pure numbers. Giant’s designers have worked hard so the suspension remains active throughout the stroke, and the virtual floating pivot design of the Maestro platform improves pedalling efficiency by reducing the impact pedalling forces have on the suspension.

Damping is provided by a Fox Float X2 Factory shock with a medium compression tune, and features high and low speed compression and rebound adjustments, as well as a lock out for those endless fireroad drags. I found the bike pedalled very well with the shock wide open, with very little pedal bob or kickback, so generally left the lockout alone. Also, while all bikes in the range are shipped with an air shock, thanks to the linear nature of the Maestro platform, you can chose to run a coil shock for maximum control, as Adam Craig did when racing in this year’s Trans-Provence.

Up front you’ll find a Fox 36 Float with GRiP2 damper with 160mm of travel and 44mm offset. There is an aluminium framed SX model in the range, which bumps the fork travel up to 170mm should you need it.

Shifting is handled by a smorgasboard of X01 Eagle 12 speed parts (shifters, rear mech, cassette, chain and crankset), and in the brief time I rode the bike, didn’t skip a beat. The first trails we hit from the lodge rolled along, with the odd punchy technical climb thrown in, and on more than one occasion I had to dump multiple gears under power. Sure, there were some noises of protest from the drivetrain, but it did as I asked and got on with the job in hand.

Braking duties are also handled by SRAM, with suitably beefy Code RSC units doing an admirable job of slowing me down on all sorts of steep terrain with nary a hint of brake fade or wandering bite point. All the controls are mounted to a TruVativ Descendant 800mm carbon bar with 20mm rise, which in turn is bolted to the forks via a stubby TruVativ Descendant stem. A 150mm drop Rockshox Reverb held the Giant Contact SL saddle in place, and all the control points felt absolutely perfect right from the get go, with minimal tweaking needed.

The wheelset is Giant’s own TRX-0 Carbon WheelSystem, have a nice fast engagement and the 30mm internal width gives a nice profile to the Maxxis tyres. Up front we have a DHF 2.5 WT 3C MaxxTerra EXO+, paired with a DHR II 2.4 WT, 3C MaxxTerra EXO+. We all know how good this tyre combo is, and it’s great to see Giant speccing the EXO+ casing both front and rear – these tyres are ready to race and don’t need throwing in the bin before you’ve even turned a pedal in anger.

So, let’s see how it did in the woods. Read on for my first impressions:

    why a seat tube of 431 mm on size small? is too high for short people, like me…

    “Too high” in what way?

    The seat tube on my 2017 Giant Trance 2 (medium) is 43 cm as well, I’m 5’8″ tall (which I don’t think is short, but other people do) and the fit is perfect – I like a high saddle, and I can still pedal perfectly and get my feet down when I need to.

    But even if I was several inches smaller, the 43 cm seat tube would not be an issue – a Small frame would still provide good stand-over height, I’d just have to run the saddle a little lower, like the Cool Kids do…

    Too high as in too high .. like the chainstays are too long as in too long and the wheels are too big as in too big..

    “All models come in S, M, L and XL sizes, with the exception of the Advanced Pro 29 0 and 29 SX where no small size is available.”

    Obviously the main change is that Giant are building L/XL bikes only now and anyone needing a smaller frame will essentially just get a bit chopped out of the top tube (though they do at least supply shorter cranks) chain stays are identical in all sizes because that’s as small as they can go with 29” wheels on small bikes.

    “All models come in S, M, L and XL sizes, with the exception of the Advanced Pro 29 0 and 29 SX where no small size is available.”

    It’s hardly surprising as for the last 5 hrs or so just about every review of every MTB is for L or XL complaining it’s too short … from 6’+ journalists… it appears that today any shorter journalists are only allowed to review components but when did you last see a review of a XS or S ???

    That’s basically it … they don’t make smaller top end bikes any more.
