Druid v2 vs anything?

I’m really considering the Druid v2. My current trail bike is a stumpy evo. How would that Druid compare to my Evo? And what else do you recommend to replace the Evo? For the record, I love the Evo. It’s been my favorite bike, but I’m itching to try something new. I also have a trek top fuel for the pedally stuff. I am a fairly advanced rider, riding all around the country, but mostly around the front range of Colorado.

Reserve 28XC for general trail riding

I took advantage of the crazy deals Jenson had on Reserve wheels recently and bought a Reserve 30SL rear and 28XC front wheel for around $1100 CAD total to go on my Transition Spur for general trail riding. I would have preferred having a 30SL on both front and rear but the deals were for individual wheels that they had on closeout. I would likely have bought We Are One Faction wheels instead if the current discounts wouldn't be only for wheel sets with hydras as I prefer the reliability and sound of DT Swiss 350s. If I wanted to get a set of Factions with 350s it would cost at least $700 more than what I paid for the Reserves. The triad/sectors seem a bit overkill weight wise for the Spur. Also the rumours about Industry Nine buying We Are One or them being in financial trouble give me a bit of concern about how long the lifetime warranty on them would actually be. I think Santa Cruz will likely be around for quite some time.

After purchasing the wheels I came across some reports of spoke tension issues with the 28XC wheels for heavier riders. My weight hovers around 200lbs so I'm not super lightweight but my riding style isn't very aggressive either. Since the wheels haven't yet left their box and I'm still within the return window I wanted to ask if anyone has experience running the 28XCs for trail riding. The trails I ride are mostly blues on the North Shore and in Port Moody, I've ridden the same trails on my hardtail with Newmen alloy wheels and Tannus inserts for a couple of seasons without any issues other than some slight truing. I'd be riding the Reserves with the front and rear Tannus inserts as I like the protection and ride feel.

Broke the frame on my 2020 29" Giant stance 2, kinda need help on what to do now.

As mentioned I unfortunately have broken the frame of my 2020 29" Giant stance 2, ideally i would just like to purchase a new identical frame but there don't seem to be any available at the moment.
(At least in Germany)

My question now is, what would a frame be on which I can mount the parts of my Stance while buying the minimal amout of additional parts.

(Since I live in a somewhat flatter area at the moment, and don't see this changing in the next 5 years or so I'd have no problems switching to a hardtail, im also unfortunately not eligible for waranty on the frame)

Any help is greatly appreciated

Rear fender for 29 inch?

Im looking for some advice on what kind of rear fender I should get for my Rockhopper. I commute on my bike a lot, and will even ride in the rain and snow, but I hate when I get sprayed with water and mud. If you have a rear fender on your bike and it works well, please let me know!

Anyone use Lactigo? Huge price increase looking for alternative.

I've been using Lactigo for a while now. It was expensive, but I could swear it helped. It could have been a placebo effect with that menthol tingle on your quads lol. Anyway it just got a lot more expensive. They just raised the price to $55 a bottle. That's too much for me now. Wondering if there are any cheaper alternatives that anyone has used or a formula to make your own. I've seen on some formulas people who have made their own formulas using sodium bicarbonate and menthol but they don't include how much of each ingredient they use and how they mixed it.

Why you don't watch vidéo if it's youtube link ? Real question , no offense :)

Hey riders,

I've posted several videos on this forum, and every time they were YouTube links, very few people watched them. However, when I tried uploading a video directly to Reddit, I got lots of upvotes and comments.

The only explanation I can think of is that most of you use Reddit on your smartphones, making it inconvenient to switch from Reddit to YouTube. But I'd love to hear your thoughts to better understand this and improve the visibility of my edits while getting more feedback.

Sorry for the English, ChatGPT translated this for me. Thanks in advance for your feedback!

I did a mistake?

Soo, just came in Germany and was thinking of getting my first bike here, budget was very tight, somewhere around 300€, and I was watching for some used bikes, but accidently went to a bike shop in my town and saw new Trek marlin 5 2022 for 395 €(cheapest bike in shop), and bought it. Do you think this bike is okay for beginner rider and for this price? P.s haven't riding bikes for 9 years I think and the last one was Chinese double suspension bike.

Would you pay $500+ more for this build differences?

Identical bikes, frames besides the wheels and drivetrain. Drivetrain: One has Shimano Deore M6100 the other $500 extra model has Shimano SLX M8100 crank, cassette, shifters /XT rear derailleur combo.

Wheels: one has Shimano HB TC500 +Stars J30D the $500 extra model has DT Swiss 370 hubs with DT Swiss M1900 rims.

Thanks team. This is for mostly Trail riding. Xo

QR wheels

New Izzo on the way

Just picked up a core 2. Crazy sale. SLX build, $2800. First full sus, ride a HT here in Chicago but have been looking to get a FS. Was looking at santa cruz and some other higher end brands, but in the end I am a pretty average rider and decided to go with the Izzo. Hope it is worth it!

I use a YT Jeffsy to commute to work, and I love it! what tires next?

Hi everybody,

I know it's not its intended use, but i'm having lots of fun, I mostly use my Jeffsy to commute to work (about 9km - 5.5 mi), it's the best part of the day and I do stairs, some small jumps and a lot of wheelies (on a cycle path where I am just about alone),

I have XC tires on (maxxis Rekon race in the rear, Forekaster in the front),

what do you suggest for the next tubeless combo? keep in mind i ride on tarmac 99.5% of the time...and only if it's good weather, otherwise I get on my motorcycle and rain gear.

I'd like to try some faster rolling tires, not slick stuff but more road oriented than the combo mentioned before...and I'd like them to be at least wide as 2.30, don't want to mount real skinny road/gravel tires. THX

and ciao from Italy!

Fox said they wont service my shock, what do i do now?

Hey guys! I am from Europe and i have a Nicolai bike with a Fox Float x2 from 2018.
There now seems to be air in the oil (it does the typical smack sound when compressing).

So i sent it to fox, only to get it back 2 weeks later with a note saying something along the lines of "Sorry we dont have any parts for it so we won't service it"

So i have been trying to figure out what to do. Servicing by myself is an option but i could only buy the parts from America and wait 3 months until i find out wether they are actually the correct ones. The oil also is not available so its 85€ for 1qt with shipping.

Does anyone have any suggestions on what to do?
I feel like throwing a shock into the trash because of spare parts running out 7 years after it was built is too soon. (I usually ride dirtbikes where you can get oem parts for a 35 year old bike without issues...)

Shock pump question

Ok, so I'm no bike mechanic, but I've got a shock pump for adjusting suspension on my bikes. I was recently using it on a one-up dropper that allows you to add pressure to speed up or slow down (no idea who would want it slow) the speed of the dropper coming up. I would get it to pressure then start taking the pump fitting off the valve on the dropper post only to hear the dreaded pffffff of air escaping. Anyone know why I'm experiencing this? I know it's niche because most droppers aren't like that but it's a PITA

ShockWiz + ZEB - any feedback?

Bought a ShockWiz last week and it has been nothing but frustrating the last few days. Has anyone successfully made it work? I'll try to summarize my problem, maybe I'm doing something wrong. For reference, it's a 2023 ZEB Select+ with 170mm.

I can't calibrate the shockwiz because there's always a "not enough pressure error". The first step tells me to depressurize the fork (I figured that having it empty doesn't work), so I tried to slowly creep up the pressure until I got the extension step approved. If the fork has no air, the pressure reading remains at 0.0psi and I get the error message. I figure I need, at least 20psi on the fork for the approval (measured by the shock pump, since the shockwiz still reads 0.0), but this makes it completely impossible to bottom out the fork for the next step! Yesterday, I managed to almost bottom it out (needed a ratchet strap though), with the app reading almost 60psi, and got the step approved, but next the, fork extension comes up again and fails because "a sufficient pressure change was not measured". The app reading went from 0.0 to 60 psi, how is this not enough? Was so hyped to try this, but now, I'm thinking either the device is flawed (bought it used) or it is not compatible with these newer forks.

E-mtb tires on a hardcore hardtail

I am in the process of building my very first hardcore hardtail and I stumbled across an absolute steal on a pair of Schwalbe Eddy Current tires. My thought is that the extra protection would come in handy since the tires take way bigger hits than on on a fully. what are your thoughts on this? Go/ no go?
