Climbing Yes, the Sentinel's head angle sits in what used to be downhill bike territory, but that doesn't mean it climbs like a big, sluggish gravity sled – far from it, in fact. The overall weight is very reasonable, especially considering the lack of any lightweight carbon components, and it felt more energetic on the climbs than I'd expected.
The 76.9-degree seat tube angle is in-line with the latest batch of bikes I've been testing, as is the 613mm top tube length. Those numbers, combined with the 30mm rise bar meant that I felt right at home the moment I sat on the Sentinel.
It's on straight ahead, technical sections that the Sentinel's length and head angle are beneficial – there's a level of slow-speed stability that makes it easy to maintain forward progress on tricky, chunky climbs.
There was minimal pedal bob during seated climbing, and a small amount of motion from the shock when I shifted my weight forward during out of the saddle efforts. Overall, I was content leaving the shock in the fully open position for the vast majority of the time. I'd put its climbing manners on par with those of the new Norco Sight, and a little behind the Ibis Ripmo, which has a shorter wheelbase and a slightly more efficient feeling suspension design.
Now, in saying all this, the Sentinel is still more focused on the descents than the climbs. It's very manageable on tamer terrain, and I was perfectly content pedaling it around for 4-6 hours at a time, but it also isn't going to deliver that super snappy, turn-on-dime feeling that would come with something shorter and steeper.

LOL. New not necessarily meaning brand new, perhaps I should have stated different as most were used, just new to me. I'll wear my Carhatts out until they burst into flames. Literally the only thing I spend any money on is mtn bikes and dirt bikes. Thrifty has its benefits.
No need here, best bike I´ve ever ridden. I also bought it as kind of a mini-DH in mind (what it also is capable of doing) but it´s still so versatile. Geo was REALLY ahead of it´s time back then.
The Bomber CR is similar to the Van RC, but was released for a bunch of trail bike sizes and strokes. Much like the Van RC, it's meant as a budget friendly starter coil.
You're not going to get a $600 shock for $300. The lack of features reflects the price, much like how the old Van RC is. I'd rather pay $300 and get 1 or 2 less adjustments and insane reliability, whereas I pay $700 for something like an Ohlins and rebuild at the same interval of an air shock.
I rode the Van36 for a long time. The small bump compliance while still having enough support for bigger hits was great. Air has taken over, but I do think that if some fork companies put the coil forks with pro EWS riders and they started winning, coil would instantly become popular again. Coil rear shocks have become more popular of late on EWS.
I've got the Rockshox Boxxer coil on my downhill bike and actually prefer it over the air, but I'm a utilitarian person, along with a "set and forget" mentality. The service interval and the ability to just not worry about how much air I have in the fork or my sag settings is great to me. People are digging the Marzocchi Z1 coil, I think the new Rockshox enduro fork will see a coil option as well.
Those curvy frames were divisive but they sure were unique and I love 'em! Glad I got one.
There are more than enough straight/angular brands out there!
It is important to set clear boundaries or the categorizations could get too convoluted.
I bet a large with 500mm reach and 65 degree HTA will be popular in say 2-3 years.
After this - it's back to messing with handlebars; more backsweep (like SQLab) and upsweep (like Newmen) - you heard it here first.
Given listed effective TT numbers, I think actual STA for tall guys will be pretty close to identical between Sight and Sentinel.
But $7600 CAD for a GX build? Wowzers. An aluminum model will likely still be up in the 6k range. Even if I were a fan of carbon frames in this segment of bike (I'm very much not, but that's me), that's still a tough sell.
Looks great though!
Transition has always been great (and my LBS North Shore Bike Shop too for often stepping up) at helping customers out even when beyond their warranty timeframe... now it's just more official!
$300 cheaper than an SB140
Not to take anything away from the good folks who make products in other countries, but it makes sense to buy local.
If Transition made their frames in the USA, I'm curious if they could compete with GG.
I did, however, just pick up an aluminum Mongoose Nugget frame that I'm excited to build up. Pretty beefy.
Why would you expect anything different? They are not apples to apples in any way...
JKN, but we didn't really get the "Super Sentinel" everybody was talking about. But I'd guess Transition built the bike they thought they would sell more of??
Both brands have some wheel size/travel/chain stay length restrictions. Also both brands are doing more than one model with the same front triangle so I'd guess that also creates a hurdle.
I didn't know the Sentinel shared the front triangle with the Patrol?
In the end I think both Transition and GG make some great bikes. Can't really go wrong!
also doesn't cost as much
Crazy thing is GG only made their first Carbon frame last year, and their first XL carbon frame a couple months ago... Think where they will be in 19 years!
And on that note crazy that Transition has grown so much in just 20 years themselves...
I've considered several times over the last 2 years to buy an alloy Sentinel (always ended up not doing it because people kept telling me they're awful climbers), I guess this new version will be out of my radar.
On the other end, wouldn't be surprised if Transition has a more "Patrol-ish" 29er in the sleeve, or even actually releases the Patrol as a 29er
since all the muppets are buying effin stupid carbon for no reason but looks, transition does not put any effort in the development of a reasonably light aluminium alloy frame (bitches!). And then you‘ll end up with a 4,2kg frame without shock in size m.
Look at Norco sight, gt force 29 and v1, it is quite ridicilous. So no, just cut the crap and buy from companies who put real effort in aluminium frames and enjoy no disadvantages whatsoever compared to carbon for 1000€ less. Banshee is a good call.
- Megatower
- Enduro
- new Scout
- Strive
- I heard somewhere that Norco cancelled the Sight frameset alloy
Developing a good alloy frame (in a league with Liteville, Nikolai, RAAW, Commencal, Pole, etc) takes lots of resources, which a niche brand such as Transition probably isn't going to invest after already blowing their R&D budget on the carbon model. Therefor they would probably end up making a very mediocre, underdeveloped alloy version of this frame.
Alloy frames should be left to companies that specialize solely on aluminium rather than carbon, or companies big enough to be able to afford a proper R&D process for both alloy and carbon.
“ We know a lot of people are looking for alloy options, and it's something you will see more of from us eventually. We can't share any specific timing or details yet, but we hear you, and we aren't ignoring the category. We're a small company and when we develop something we want to make sure we do it right. --Sam”
They only use one height per size for effective seat tube angle, which is what everyone else does to derive their effective seat tube angles, except without publishing that height for each size. So super good on them for publishing the heights, but that phrasing makes it seem better (multiple heights & angles listed per size) than it is.
better?
Some outlets were celebrating the MK1 Sentinel's geometry as "pioneering" at the time when in reality several brands were already doing the same
"Lars at Transition contacted [me] after he’d read that article and tested with shorter offsets and longer bikes. He wanted me to help put into words what he was feeling on the trail, to clarify in his own mind why it was better when the industry orthodoxy seems to think it should be worse and also to justify his theory up the food chain at Transition I guess."

Still love what transition is doing as far as geo. But bring back the metal!
Just give em some time
Perhaps they don't want aluminum taking up their carbon sales and are switching the release order? (Wonder if profit margin is higher fir the carbon?) In the past the metal bikes came first I assume because they were trying to get new bikes to market ASAP. And then the carbon bikes came when they were ready...
Something's different... But fir sure I'd like to still see AF versions...
Also why post the chainstay lenght as 440mm (size large) if it's the same size for all bikes? Kind of implies that:it differs, yet it doesnt.
Banshee has long and short dropout options. I think mondraker and propain dh bikes do. Transition dh bikes used to. Nicolai bikes does.
In the AMA Sram guys said it's the counter measure spring, but it's not that either, the shock still knocks with the aircan (and CM spring) removed.
@easyslorider: again, no. First of all, my shock is a 230x65, so max travel for the ETE size. Meaning no stroke reducer. And both my and my friends shocks are horizontal or almost horizontal. Plus I had issues with the noise when the bike was new, it went away a bit, but is now very loud again after i did the 200h service. Nothing was wrong with the bottom out O-ring, so no, this is not the issue. Plus said friend of mine shot a video of the shock making the noise with no aircan on it. And the noise is present on movement, your rattling would be present by just shaking the bike around, not moving the shock. Which is the exact opposite of what I/we experience.
Something is wrong in the damper.

If someone finds out what is causing problem, please report here
@mikekazimer is knocking sound on this Super Deluxe similar to my?
It's great for everything! IF "everything" is limited to this specific thing...)
This has become a common thing to see in PB reviews. Perhaps some expectations need updating?
$5400 for a GX build isn't for the riders. My full carbon capra pro race X01, fox factory build cost $5400...
The GX build should cost in the $3k ballpark if you remove the margin for shops.
what were you saying about it being a 'good' build for $5400...
If they sell more bikes then success..but kinda underwhelming in all respects for me.
I like the swoopy/unique look of the first Gen frame. I'd just install a 170/180mm fork on first Gen and call it perfect.
-Cons..not the mini-DH..bike some may be looking for? It has slightly longer stays, more travel and a slacker HTA..how does this not retain, if not fractionally increase more of what you described in your 2017 review???
Still a SICK bike for sure and I've always liked Transitions sionszz..with this exception.
but still
GX is just not up to the sort of riding this bike is capable of, SLX 12 speed far more durable, the lower end SRAM stuff just dies and I found warranty takes weeks & weeks
Id take 10 speed Deore with a sunrace 11-46 cassette over GX eagle or NX 11 speed, might not be as flashy but it will last longer and mean more time on the trails, less time being fixed & chasing warranty
Oh and this sentinel looks great
