Eminent MT Drive? (Looking for enduro e-bike to smash laps on)

I found an eminent mt drive used (2022) but full fox factory for $3,350. Anyone have experience with it? Range, ride quality, descending, etc. I’m trying to decide whether or not to get it. I race enduro and downhill so I am experienced and I want something to be able to smash laps on and go on crazy rides. I am also considering a norco range vlt 2022 900wh, a Rocky Mountain altitude power play, and a transition repeater, but those are all a bit expensive for me right now (around $4k) and I would probably have to wait longer to get them. I also am able to find lots of info about them on the internet…

New bike suggestions?

Hello I am a freshman college student and bikes and scooters are common to get around. When I came for the first time I brought a really old and beaten mountain bike with a destroyed front derailleur (the bike is a 3x7) and I got that fixed but then just a week ago I got two flats and my pedal came off. I know how to change tires but feel it's time for a new bike. I have been riding casually riding bike for a long time and I am really comfortable with how they operate. Which is why I do not want an e-scooter. I want to get a new bike but I don't like buying used so I just wanted to ask what some recommendations for a new mountain bike would be my max is $700. I don't ride trails too often and if I do they are nothing crazy. I was hoping to get a 2x9 or something along those lines with hydraulic disc brakes and a frame with room for a 52v 20ah battery as well as electronics for a e-bike conversion in the future. I know that a 2x9 makes a dropper post hard to do as it takes the place of the front derailleur on the handlebars but I don't feel the need for one as I do t do trails often. I also was hoping to get a hardtail instead of full suspension to leave more room to the battery and electronics. I know this is a lot but any help would be greatly appreciated! Thank you!!

Santa Cruz V10.8

Hey everyone, I wanted to hear from the community about a potential upgrade. I’ve been riding a 2017 Santa Cruz Hightower for over 2.5 years now, but I’m considering switching to a dedicated downhill bike. The new Santa Cruz V10 caught my eye as a great option for fast freeride and downhill riding.

I know it comes with a high price tag, but I’m willing to invest for the love of the sport. That said, I’d love to hear your insights—should I go for the upgrade, or stick with my current setup?

xc/xcm racing rim?

Hi all,

What are the best carbon rims for XC and marathon races? I'm not just looking for a 'fast' rim, but also one that is easy to handle downhill, of course durable, and under 1400g. Thanks! And for the hub, I was thinking about the DT Swiss 180.

Moderators, can we please fix this automod keyword feature? It's not working as intended.

Example: https://i.imgur.com/DeSRl3n.jpeg

It makes perfect sense to fire off the automod about the buying guide if someone flairs WhichBike. That is a smart feature.

But this recent expansion into any other flair where it seems to just be seeking out keywords? Is objectively not working and then posts are getting removed/deleted in a scenario that does not apply to OP and they couldn't even... Like what are they supposed to "fake" buying a bike and answer all those silly questions so it doesn't get deleted?

Again, LOVE useful and functional features. This isn't one of them. Either change the keywording that triggers it or just take it off all flairs that aren't WhichBike. /u/219MSP

how to remove mineral oil stains from concrete?

I was bleeding my brakes on my balcony and my little brother knocked the full bleed cup over.... Luckily I had some old paper bag ripped up to cover the floor, unluckily it soaked through the paper and has now stained a concrete slab, how should I go about tackling this stain?

Digital Shock Pumps

This is the 2nd digital Fox shock pump that has broken seal on me in the last couple years. The first one didn’t hold pressure out of the box and this latest one lasted quite a while but now I can hear the air escaping and I’m watching pressure drop while still attached.

I screw it all the way on the threads and equalize the pressure while it’s attached. The pressure drops when I rotate the pump, especially when the hose bends. It leaks 2-3psi at a time, more if I continue to hold the pump in the same unfavorable way.

So a couple questions: 1) anyone else experience this? And 2) can anyone recommend a digital pump that doesn’t break every other year?

Anybody convert their Stumpjumper 15 to Mullet?

Thinking of going with a 27.5 in the back of my Stumpjumper 15 expert. Anybody have any rear wheel suggestions? Need SRAM XD - 12 x 148 hub from what I've been told. Also wondering what the best cassette would be to pair with the Eagle GX transmission

What seems to be the best place to look for used bikes?

I was on my local Craigslist (Bay Area) and was looking on pink bike, things seem like prices are a lil crazy since the last time I was looking (around 2020). I used to be big into mtb in high school (2014-17) and have been out of it for a while.

The goal is to get a decent al full suspension 29er for like 800-900 but I’m struggling to find anything in that range.

Are mullets & full 27.5s not for big boys?

I don't think we're even THAT big. Riding buddies & I are all about the same size. 6'4, 215 lbs.

I'm a new rider. Started during the summer, got my bike in the fall. Live in the PNW so still riding all winter (so far).

There was something about my bike that I didn't love. Couldn't figure it out. Had a couple of crashes. One was bad and took me off the trail for 8 weeks. Was wondering if smaller wheels would help slow things down. Chatted it out with the boys and brought up if I should try a mullet. "Big boys like us don't ride 27.5" is what I got.

It's kinda pointless because it turns out my bike can't do 27.5 or mullet, but I'm still curious what the general consensus is.

Carbon Fibre Frame Protection

Hey dudes. I know this probably gets asked heaps… anyways.

I’m getting my first carbon fibre mtb (trek slash 9.8) & need to know of the best option to use.

I’m leaning towards RideWrap but have seen some concerns regarding its durability & effect on carbon fibre parts.

Any help is appreciated!

Bike setup for mixed surface race

Hi all-I'm trying to figure out the best setup for a combination singletrack/gravel/road race later this year. I'm going to be riding my XC hardtail (Highball), which I currently have setup with X01 AXS-10/52 rear, 32t front with a maxxis Aspen/Rekon race tire combo. This is good for mountain biking but terrible for road or even gravel riding. I'd like to add some high end gearing, maybe add a power meter, and find some tires that would work better for mixed surface riding. I currently have Zipp 1Zero Hitops, which are 30mm internal. Does anyone have any/all suggestions for the best way to set this up?

Sram NX Eagle Dub torque

It looks like on the crank arm it says something like 54nm in torque. I don't have a torque wrench that can touch that!

I assume just giving it a good ugga ugga with a breaker bar should be sufficient. What do you all do on something that high? Any tips or tricks thanks in advance!

Which Budget Hartail For A Newbie ( Australia )

Hey all, I'm looking to get my first bike in a long time. I'm looking at a hardtail that ranges from 750-900 AUD. I plan on doing light trails and more fitness based things.

I know people say there isn't much in that range but I'm seeing a few things like the:

Trek Marlin 5
Giant Talon 4
Merida Big 7s

Out of those, what would be the better suiter or is there another brand like Cannondale or Scott that I should look at?

Thanks

Feels like the difference between 2015 to 2025 bikes is significantly less than the difference between 2005 to 2015 bikes. The gains feel marginal now and I can imagine myself still riding the same way on a 2015 bike.

2005-2015 Changes:

  1. Wheels got bigger. 26-inch wheels died. 29-inch and 27.5-inch took over. This changed how bikes rode.

  2. Dropper posts arrived. You could drop your seat on descents. This changed how people rode technical trails.

  3. Front derailleurs disappeared. One chainring in front became standard. Wide range cassettes made it possible.

  4. Through-axles replaced quick releases. Bikes got stiffer. Handling improved.

  5. Head tubes got wider at the bottom. This made steering more precise.

  6. Bikes got longer and slacker. This made them more stable.

  7. Carbon fiber became normal, not exotic. Frames got lighter and stronger.

  8. Handlebars grew wider. 680mm became 740mm. Control improved.

  9. Tubeless tires took over. Lower pressure was now possible. Grip got better.

  10. Air suspension got smarter. Adjustments became more refined.

  11. Cables went inside frames. Bikes looked cleaner.

  12. Rim brakes died. Disc brakes won.

  13. Hub spacing went wider. Wheels got stronger.

  14. Stems got shorter. 90mm became 50mm. Bikes handled better.

  15. Chain guide mounts became standard. You could run proper protection.

2015-2025 Changes:

  1. Derailleur hangers got standardized. One size fits many bikes.

  2. Electronic shifting appeared. Batteries replaced cables.

  3. Geometry evolved further. Bikes got even longer. Seat angles got steeper.

  4. Mixed wheel sizes emerged. Big front wheel, smaller rear wheel.

  5. Frame storage became built-in. Tools and spares fit inside.

  6. Cassettes got wider range. 52-tooth cogs became common.

  7. Adjustable geometry arrived. Bikes could change their angles.

  8. Tire casings improved. Sidewalls got tougher.

  9. Frame protection got better. Bikes got quieter.

  10. Frame materials got mixed. Carbon and alloy worked together.

  11. Chainstay length matched frame size. Bigger frames got longer stays.

  12. Electronic suspension appeared. Settings changed automatically.

  13. Bottom bracket standards simplified. Press-fit lost popularity.

  14. Carbon layup got smarter. Different carbon went different places.

  15. Tire inserts became normal. Foam protected rims and tires.

The first decade brought big changes. The second decade made things better, not different.

Water bottle for YT Capra?

Has anyone found an aftermarket water bottle that fits on a YT Capra mk3? I would order another thirst master 6000 from the website but it comes out to $30 after shipping…. Entirely too much to spend on a water bottle.

Buying a Giant fathom 29 2 2021

Hi guys!

I'm planning to buy a Giant Fathom 29 2 2021 mtb and I have a few questions. Anyone knows that this bike is a category 3 or a category 4 mtb? What is the max chainring size that I can use with this frame? This bike has pressfit bottom bracket, i've heard that threaded bottom brackets are better. A press fit bb would be dealbreaker for you or i should go with it?

Thank you for your help!

Gettin after it on a new (for me) jumpline yesterday.

Was at a jump jam yesterday and sent probably the biggest line of gaps I've ever done. This was the first lap going for all of them. I hit the full line about 8 times. Last gap is around 30ft I'm told.

Terrene McFly 27.5*2.8

Hey

Does anybody have any experience of the Terrene McFly tyres (in any size)?

I've used some of their fatbike tyres in the past - always found them great but spendy.

The McFly are "unusually" cheap (from the maker) so I'm looking for input

Ps - I'm not looking for recommendations of other rubber because I've tried most of them already - but always looking for a new experience

Thanks in advance

Anyone running a SRAM mechanical shifter with Shimano brakes?

How are the ergonomics? Do you have an adapter for the I-SPEC or do you use a discrete clamp?

Thanks!
