FKNA!!
Somehow my tellis dropper survived until about 2 months ago. Not bad for a 2019 but its had twisting play in it for atleast 3 yrs and a lot of play and loud creaks the last 2 years. Ive been thinking it would die for quite a while now. ]

if the SDG goes flacid a new cartridge is 65$ and takes 5 min

not sure about the bushing rebuild kit

My cartridge is still fine. The key way kit is what i would need. $40 on amazon

There has been a decent amount of machine built trails, and rail trail additions added to the local inventory in my part of the country. I really do not want to spend 5-10k on a full suspension bike, and have been considering and e-bike. I currently ride a HT and am perfectly fine pushing my limits on local single track.

Has anyone laid eyes or have an opinion on one of the Commencal hard tail e-bikes?

Same question, devinci e-spartan.

[jackstraw]

The classes never made sense when thinking about paved and unpaved use cases. Most ebike users who cause conflict are doing it on municipal multi use paths (paved or not), where throttle to 20 MPH is way way too much.

Yeah, living in a place where there are a shitton of ebikes has changed my opinion...or given me an opinion. The only ebikers I knew previously were mtn bikers and knew how to ride. This place is kooks galore. Young kids without passing a driver's exam...acting like the punks we were on BMX bikes, but they're going twice as fast with a quarter or less control. Also walking the dogs on the dirt dbl tracks and all these people on shiny ebikes that have no clue how to ride. They should just be on a regular bike until they figure out how to brake and turn...jfc.

Anyway, I'm probably going to buy a Heckler because SC locked me in as a customer years ago.

That’s a lot of ebike for the money.

I’ve ridden a similar HT 27.5 RM Growler Power Play for four years.

250W class 1, but nice build for the price?

What does it mean when a fork needs alignment?


Sent from my iPhone using TGR Forums

My understanding is that a majority, perhaps up to an unbelievable 75%, of forks come out of the factory with stanchion tubes that are not perfectly parallel with each other. This causes binding of the uppers and lowers.

Triple crown moto forks require/allow regular straightening to counteract misalignment. Single crown forks are trickier to deal with in this regard, thus my sending the fork to diaz.

I have sent in all my suspension for mtb and moto to get tuned. I usually ride them a several times from New then send them. That way I can tell the difference.

I'd be really curious about how he does this. As a former machine shop owner, I can only come up with one possible way to perfectly (well, nothing's perfect) re-align fork stanchions. That would be a fixture made from a solid block of steel, two holes bored perfectly in the exact stanchion diameter and spacing, the entire length of the tubes; one fixture for every different size fork.
The cost of this would be astronomical, even by my standards. (and you know where I work)

And that's the easy part.

The hard part would be coming up with some way to eliminate springback. Springback is the cause of any misalignment in the first place. They are manufactured in a pretty much perfect fixture and then heat treated. It's the springback as it comes out of the fixture that causes this issue.

I just don't see how it's possible to realistically achieve better than what the factory manufactures.

Now, if I was a betting man, I'd bet that Diaz is actually aligning the bushings in the lowers. Basically utilizing a burnishing tool long enough to hit both bushing at once.
That would make a lot more sense to me. I could be wrong but I doubt it.

Insane pricing. This has better parts, suspension and motor than my 2019 base model. Its 2500cad less and 1000cad less than my commencal meta am 29 essential enduro bike was. I'd prob get the core 3 though

Pulled the trigger on a S3 sized Turbo Levo Carbon. Upgraded to a Fox 38 Factory on the front and a PUSH ELEVENSIX on the back with XT brakes. Should have it this week. The $4800 deal was too good to pass up. Of course my wife who also rides a lot too needed a bike and of course we couldn't find the same deal in the S2 size so she ended up with the Turbo Levo Comp. Gulp! We'll ride the shit out of 'em and the money will be forgotten. We will have them by this next weekend and I'll post a pic or two.

[supermodel159]

^^ You're stoked. Especially with the 38 upgrade. Put a coil in it and never look back.

Fun times ahead for the LT fam!

Ok, so, I'm not going to do it, but...

What does the collective think about a kids turbo levo?

My thoughts: great for kids to get more laps with parent(s). More times up to bat for bike handling skill progression. Not so great for riding with non-ebike kid friends. Not so great when other parents chastise ebike parent (but really who gives a f#@.)

Thought crossed my mind since the kids levo is 1k off.

Knowing how heavy a 50 lb ebike is for me, a full size adult to wrangle, I can't imagine that even a 40lb ebike is very manageable for a kid.

I'd rather get a Towee strap and pull them up on their regular bike with my ebike.

[grinch]

Had to check it out. Just under 36lbs. Seems reasonable.If you have the means, great little thing for the fam ride or for jr to pound laps and spin off that energy.
Some kids like climbing at that age but a lot of them whine and complain until they get to the down, even good kids. Good tool to get them thru those few years. Its hard to get a little wheel bike up some of the climbs that we climb. There is insanely talented kids out there today because of bike parks. Add in one of those levos and we're getting the next level of talent

Well, my Levo lasted approximately 10.5 months before the motor started making awful noises. I rode it a couple more times after cleaning it to see if it'd go away and it just got worse. I took it to the local Specialized shop and the mechanic winced when he heard the noise. So... new motor incoming. That's why I wouldn't recommend people buy ebikes without local warranty support.

[grinch]

Specialized, surprisingly enough, does seem to be ready to swap a motor fairly quick.
It should work that way for any good shop when someone brings a bike in with a bosch or shimano motor as well. They plug it in to the puter, find the problem and deal with bosch or shimano no matter what the bike brand is. I'm not sure a lot of bike shops are up to speed on motor diagnostics though. A friend has had his bosch motor fixed the next day a couple times. Parts seem readily available for them. Yt told me just take it to a lbs and diagnose it and theyll pay. Then shimano dropped the ball until yt stepped in and called shimano. I think even if i bought a bike with a shimano motor from a shop its going to be in shimanos hands when and what gets done, not the bike company. Shimano wasnt returning calls or emails to the shop i went to Brose isnt fkn around with their golden goose , specialized. They often need replacing though so its a well known flaw so theyve excelerated the swapping procedure to mitigate blow back. My 1st shimano motor died after 2 months at 1800km. This latest one im at 8500km and , knock on wood, its still working. I'd consider any of them at this point. A quick brose swap on a motor that runs well when it runs but most like will fail repeatedly, shimano that feels good but has a decent chance of failure and possibly shimano has a swap ready or bosch that may break or may not break one part or another, good availability on parts, generally last long but still not perfect and absolutely hauls the mail. Yamaha like bosch with a few more failures. You should get specialized level service from giant if your yamaha dies? Shop dependent in all these cases. We should be able to plug them in to our own computers and share directly with a motor company. No humans involved. You spit out an error code and they spit out the service.
We see service centers now for brose, bosch and ysmaha and ive found a guy in europe that now services shimano and also sells rebuilt ones at decent prices. I can swap in an ep8 in place of my e8000 with just splicing on 2 ep8 wire connectors on to my existing wires. For that reason and yt's good communication i'd buy another yt. I do want a bosch though. More pulling power and a fair bit longer range but i'd consider a spesh with similar power and range, pricey though. The newest brose seems more durable. Kind of hoping yt get a new bike with a bosch motor to be honest. That'd be a good price, good frame, power, range and serviceable for yrs. Im not against keeping a spare motor as well

Anyone have any experience with Rambo bikes? I have a pursuit 750. Fell off the rack. On the highway.

I may start another thread looking for some advice w what to do. Fork is toast (but it’s replaceable). Bike shop guys says the frame is bent, I can’t see how it’s bent and his “measurement” left some questions. Looked like he was tweaking out (and I can get a replacement frame if needed). Just seems like no bike mechanic wants to get involved w the electronics (which should be ok in theory).

Thoughts??

[grinch]

An electric bike shop msy be best if you have one you can go to. Chances sre they'd have the most experience with that.
Maybe borrow a fork somewhere and go for a spin to see how the frzme alignment is? After a good mechanical and weld/crack check

I like my Brose motor when it works, but I've watched a few YouTube videos on servicing them and it seems like there's not great sealing around the spindle. So water gets in and destroys the various regular and sprag bearings. My guess is that's what happened to mine, which is nuts because I washed the thing <10 times. I did ride it in some pretty heinous shitty conditions during the winter to do trail work though. There were also issues before with the belts wearing out but apparently the latest carbon belts are very durable. My buddy who's on his 3rd(?) motor thinks his was a belt once and sprag bearings the other 2 times.

I'd love for Santa Cruz to put a Bosch in the next version of a Bullit (like the Crestline). I just like how my Nomad rides, but want a better motor than the old EP8 (and larger battery) that's in the current Bullit. The SRAM/Brose one would be ok too, since there's lots of SC dealers to deal with motor swaps, but I'm definitely Bosch-curious now that the latest ones have a nice top tube display like Spec/Brose.

[grinch]

I wonder if the guys servicing motors add seals? I think in reading about the guy that services the shimanos, that i follow, was adding seals. I know he's always stressing a particular grease he swears by but i think seals were mentioned.
I think the new ep801 has a focus on being well sealed and the motor is supposed to pull much better. I'd take that with a grain of salt though and its still not going to be as efficient with the battery. Biggest thing people notice going from shimano to brose or bosch is how much longer they can use boost/turbo. I only have a 540w battery and i try and squeeze in as much eco and trail mode as i can. Eco or trail on pave or rail trail on the way to the mtb trails. A lot of days i wish i had more or its some serious battery management. New sram system is pretty attractive and then brose' new 48v is another step with the added heat management 48v will accomplish. 48v and some added sealing and it may be it but then are we going to get some good options with pinion mgu next year? I think i'll milk mine another year with maybe a 720w battery and/or a cheap rebuilt ep8 upgrade then sell it with the ep8 and rebuilt e8000 with both batteries in a yr or so

Yeah, it sounds like the 3rd party motor service centers (for people out of warranty) add seals. The one video I was watching yesterday specifically pointed out that they do that. He said it doesn't fully eliminate water ingress, but massively reduces it and correspondingly lengthens bearing life.

[grinch]

Ok cool. Seems like thats a big issue for all of them. I occasionaly pack some grease around my axle. I prob should be doing that more often
