Anyone tried the Focus Jam2 Plus LTD?

[MartinW148]

Me and a good friend both have JAM2s, mine's a Ltd, his is a Pro, and we absolutely love 'em. Have both had some technical gremlins, especially after washing, but nothing that stops play. Both still waiting for TEC packs to arrive but still getting 2-3hrs of mostly-boost riding.

Off down through france in a couple of weeks to find some woodland, hope we find some decent trails.

When you say technical gremlins after washing, did you get battery drain?

Mine's a jam2 carbon and the only two tech issues ive had are the magnet for the speed sensor got knocked off (superglued in place) and after the first wash (which i didn't go anywhere near a jet wash) I took it for it's first service and it had bettery drain from four to two bars in less than two hours (in the back of the car).

Actually make that three, the front brake needed some tlc after the last ride but i'd call that wear and tear.

Mine requires two presses of the top button to start it, every time, and can get truculent after a good wash (again, never with a pressure washer). Turn it upside down, bounce it a bit, squirt in some WD40, and it's ok, but it's been logged as a warranty job so hopefully will be sorted soon.

Not had issues like these. I did put some dia-electric grease on the charge port contacts when I noticed a little green corrosion appearing early on.

 

[R120]

Suspect this might be a Focus specific issue, as of all the shimano bikes its the one which has the most custom components, rather than the generic system.

 

[Eckythump]

Think you are probably right. Maybe worth looking at the RoPD connector and O/1 button.

Now you come to mention it, mine always takes two presses to switch on (always has), I thought this was just a curiosity of the system. Has this been recoginsed by you LBS as a fault?

Mine too thought it was a Focus thing ....sometimes takes 2/3 goes . to get it started.
Hardly worth taking it back on 50 mile round trip to fix.

 

[Eckythump]

Is it really taking two presses or are you not holding it long enough on the first press?
Mine comes on first go but it is always longer than I think it should be.

Definitely two presses, the first press can be 30 secs and nothing springs to life.

My understanding is that the systems goes into sleep mode after a certain time and the first press is required to wake it, but that's only a layman's interpretation of what I've read so far.

I've now had my Jam2 Ltd now for 9 months and done just under 1200miles. On my 3rd chain and second cassette. Tonight I have taken off the Rekon tyres and put a Maxxis DHR ii on the rear and a DHF on the front. Will be out on it tomorrow night to see how they perform.

I too have to do the double press to get it to fire up.

 

[highpeakrider]

Mines always more then one press, I assumed it was me....

Are you sticking with the 2.8 tyres or going smaller. I was thinking of keeping the plus size rear and changing the front for maybe a 2.6 (40mm rims)?

Maybe it’s me. Always assumed a second press was coz I hadn’t held it long enough the first time as it doesn’t always take two....

The manual says to push and hold the power button until it lights up blue.

I'm sticking with the 2.8 tyres, I like the chunky size

 

[Trung]

It takes me 2 presses as well on a sam2

 

[Injidup]

Just tried my Bold. One long press does the trick.

Ive only had my Jam2 for 9 days. Have been out for three rides on it. 1 x rolling Hills Road Ride @ 29kms, 1 x quite hilly Road Ride @ 42kms and 1 x Technical Hill ride (Makara Peak) Wellington @ 12kms. (couple of 20km road rides on my Haro Double Peak Hard tail as well). I'm 57years old and 116kgs and love this Jam2. 42km hilly road ride on trail mode showed 6km range left. Makara peak used 2 bars out of 5. I do have the Tec pack but have not needed it yet. Suspension is pumped up to allow for my "Generous" Build and even on the down hill at Makara Peak I have not bottomed out anything yet. Love this bike!! But yep it takes 2 pushes on the start button to crank her up.

Must persuade my daughter in Tauranga to buy one of these for me to use when I visit ....ps I ,m a bit lighter but a LOT older than you and absolutely love my Jam2
Have fun

Had mine for 2 months now it's been great fun. It's the Ltd 29 model and upgrades so far are cockpit(bar,stem,grips) and front fork. Tyres are next on the list as the continentals that come on it are terrible. Also takes 2 presses to start up and issues so far are a leaky rear shock but it did get sent to flat of a 6ft drop a few times lol.

Will probably try a 2.4 with a grippier tread (Schwalbe Magic Mary?) for serious mud-plugging next.

Have been on slippy mud/rocks/leaves all week near Angouleme and although it wouldn't have made much of a difference what tyres you were on, a little extra edge grip on the corners would have been reassuring...

Hey all, new here and just picked up a new LTD 27.5". Got a really good deal on mine so looking to upgrade some parts. Wondering if anyone could tell me if the RS Lyrik in 160mm would be ok and not to much travel? Will my stock wheels fit?

RockShox Lyrik RCT3 Solo Air 160mm Tapered 27.5inch 15mm Fork Diffusion Black

Looking forward to being a part of things here!

 

[Bri-72]

That is a non boost fork (100mm axle). Pretty sure you’re wheel and current fork is boost (110mm). You’d need to check whether you’re wheel I should easily convertible to 100mm. Also you may lose some tyre clearance on a non boost fork.

In terms of travel, I’ve certainlyfitted a 150mm Pike Fork to mine which is 10mm extra but hasn’t altered the handling much. 160mm would slacken the geometry even more.

 

[BammBamm]

Ok cool, thanks Bri. I think it's this one I want?
RockShox Lyrik RCT3 27.5inch DebonAir 160mm Charger 2 Maxle 15x110mm Tapered Fork Black

Just took her for a ride. So much fun and handled everything I threw at it really well! Slashed a sidewall on the shitty tyres it came stock with. So what tyres are people running??

I'm thinking 2.8 DHF up front and 2.5 aggressor rear? Converted to tubeless

Not on my Bold. One press no matter how long does nothing. Always two presses.
Got used to it, no dramas.

 

[Bri-72]

Bammbamm yes boost is I think what you need. I would check the axle to crown measurements off the sram website for the lyrik and compare to what’s in the bike. Ie are you raising the front end by 10m, 20mm or more. In terms of impact in front and handling. Do also bear in mind for warranty focus could state you’re using s long fork than frame was designed for.

Tyres i went for ultra grip so magic Mary’s front and rear.

 

[Eckythump]

The originalJam2 Factory comes with a 150mm fork and rides well. Don’t think an extra 10mm will hurt it. I have a 160mm air shaft kicking around but have not tried it.

I went to do the firmware update using e tube but it just hangs at about 40%. It’s now “bricked” my bike and can’t do anything! WTH Shimano!

Ouch that sucks! Someone else had it happen in this thread: Bike bricked during firmware update? - EMTB Forums

This link might help - it seems to suggest to keep trying (but might need the latest version of etube app): firmware restoration procedure
