It's really easy, 4X 2mm screw on the plastic cover and only two bolts I think they are T30, (not 100% sure off the of my head). The back one is a bit tricky but you can get it on and off with the chain ring on still. Then just shift it out, then I just let it hang by the back bolt while working on the cables.
 
If I had to choose one it would be the CX, I can de-tune it to ride with the analog kids, and have the power for the full gas days, the Bosch app is really easy to use so that fully helps.
 
I had a quick parking lot ride on a Lrg CX and I was struggling with the steep ST. I slammed the seat back, but that still gave me the forward over the bars feeling. At 6’ long kegs the high seat post naturally puts me over the bars on these 78* ST bikes. This bike comes stock with 15mm under the stem, but only 20mm max. Not sure why Transition cuts the steering tube so short. Raising the stack height will hopefully move my weight back. Higher rise stem and 50mm bars looks like an option. Does anyone else struggle with this?

Is the motor clunky going down hill like all the YouTubers mention?

Ok, so after a few more rides on the SX, dropping the motor twice and a moment of zen... I have been chasing what I thought was banging cables in the frame turned out to be the SX motor. Yeah it sounds just like loose cables in the frame, now that I know what's making the noise I'm "ok" with it but its defiantly a thing.
 
I guess that the SX would be lighter, less expensive and more suited for a casual rider at a lower price point. Best for city possibly.

I'm really really curious, why the SX though when the CX is just better in every way?

What are the weights again? 18ish vs 22ish? That’ll make a big difference in how the bike rides. I’ve done a lot of miles on SX now, it’s great. More punchy than any of the other SL motors, decent range, if you’re out for an all day XC mission or a ride with mates it’s great.

The only times I’d take a CX over SX are for winch/plumet power hour lapping or for towing kids. Towing with a SX is possible, but harder work. Otherwise, take the weigh saving.

You're so confused.

There's is no price difference and mostly more experienced riders choose the SX models to get a more bike like feel
Also, some people don't live in actual mountains and a full power can make the trails a bit boring.

Never ever 4 kgs.

1 kg difference at the battery and 700 grams at the motor. Not that much.

Honestly for me the rattle would be a deal breaker, otherwise I'm down for lower assist
 
Been riding the XT CX for a few weeks now,Low with 160/170 travel .
Amazing bike,balanced geo,great suspension,popy feel... Overall very happy with it .
Also, ZERO squeeks from the frame,bike runs very silent and the gen5 motor is very smooth.
Only wish they have specced Mavens instead of Trp pro's, not impressed with them power wise at all.

Per Transitions FB, it’s 2.6kg:
SX - 18.67
CX - 21.31

Isn’t the CX famous for rattling? Although the cables in the down tube on my CX pivot rattle worse than the motor

The gen 5 CX doesn’t rattle, the SX hasn’t been updated and rattles just as like the gen 4 CX. The SX bike I did a demo on was super quiet except for the motor, not as bad as my old EP8 bike but still enough to be annoying.

The SX vs CX , both XT build .

Lyrik vs Zeb
Lighter wheels on the SX (Rims, spokes niples etc.)
Carbon cranks vs cheap alloys.

It all adds up to the weight but still for me it's a no brainer. For anyone looking for light assist, with the new mod, you can set it up to work exactly like the SX , 600 wh , 60 nm but WITHOUT that rattle .
 
My CX with Zebs and Gravity casing tires, weighs 48.7 lbs,(50.3 with the extender on) my SX with 38s (bumped up to 170, heavier fork) and grav casing tires weighs 44.2 lbs. I like the SX when riding with the young, fit analog kids and brought it to the bike park last weekend. The CX is quieter but I only use it with the "full gas" group.

Yeah the TRPs are one of the reasons I bought the Deore version and swapped out all the parts, seen a lot of those come back to the shop leaking.

I'm a total Transition fan boy and have been patiently awaiting the CX-R version of the Regulator before replacing the Relay. Well, that and for my divorce to be finalized. It REALLY needs a Reach adjust headset as standard.

But I have to admit, the Crestline Spectre has captured my interest, a lot in fact. It's got some cons like the dropper insertion (huge one actually), but some real Pros including frame only, the DJI & Reach adjust.

I was really sold on the mid powers when I bought my Relay, and I don't regret it. It's just I've moved on and technology also marches on. It weighs 45#s with dual coil, dual DH tires, pedals and tools on board, so probably a 49-53# spec in a full power. But I find it a bit annoying that I spend 100% of my time in the highest setting on the Relay and consider the other settings totally useless for my needs. I'd rather ride my pedal bike, a 28# Smuggler (admittedly set up very light and fast) than ride the Relay in the low or mid settings.

Thanks for showing us what you got.

I have the crestline and the regulator and the main negative on the crestline is the dropper insertion limit. I was doing some steeps today and I thought my dropper was all the way up. Suspension wise, it’s a dream. We can’t have it all 😊
