E-bike maintenance

As I get older and fatter, I'm always looking for reasons why I shouldn't buy an e-bike. Usually just the price is enough, but in moments of weakness, one of main points, during my inner dialog rants, is that they are terribly unreliable, always breaking down, and all use different hard to find parts. Is this wishful thinking, or spot on?

Are the uppers on the fox 38 29r and 27.5 the same?

Jenson currently has the fox 38 grip 2 27.5 for $299 so instead of servicing my damper, I was wondering if it's possible to just swap the uppers but again I'm not sure if they're identical. My fork 180mm travel and so is the on Jenson, I would also get a nice upgrade kashima the process

Polygon T9 or Superior XF 979 TR

Looking to buy my first real bike.

I’m really split between these two since they are currently the same price @2499 usd. I’ve been riding a 1998 proflex so I def need upgrade lol.

I’m about 6”1 and 230 riding mostly in DFW with occasional trip to Arkansas. I’d say I’m an intermediate rider with good stamina and power.

T9 has great features including xt drivetrain and amazing brakes but needs upgrading on the chain and wheels/tires. Also this bike reviews as heavy at 36 lbs but that should be mitigated with new wheels. Overall might be good for me since I’m thicc and could handle the extra work for uphills.

XF 979 has less robust suspension and lower quality drivetrain but has higher bottom brake height, which is appealing to me, and is 10 lbs lighter because of carbon frame. I would probably upgrade at minimum to xt shifters.

Alternatively, I go with the XF 999 which as the xt drivetrain for 350 more (not sure it’s worth it??).

Any thoughts on these bikes/brands and do I seem to have a good understanding of the pros and cons of each? Because my bike is so dated, I’m not sure about geometry.

Which brings me to my next point! Both are recommended as large but with my older bikes (dual suspension and a hard tail) large felt small. Is that simply because older geometry or something else? Should that influence my purchase/geometry?

Overall, it seems like the superior the fixes that are suggested for the T9.

Thanks for input!!

Atherton A.170 or Ibis HD6 or Yeti SB165

I currently have an SJ Evo Expert, but have been doing a lot more black/double back tech (more drops than jumps) and looking for some extra/better suspension travel, brakes with more bite, etc.

I’ll still be using it for climbing as well, and from what I’ve read/watched, the three enduro bikes listed in the title still climb fairly well for enduro bikes?

Looking to do the same components on any of them (Fox 38 factory 170mm, dhx2 factory, X01 AXS, hope t4 v4, carbon rims, etc, I’ll buy a frame and build if needed) so it would mostly be down to rear suspension setup differences and how well they climb and descend.

5’ 8”, 150 lbs. Budget is around $11k or so, but spending less isn’t a bad thing ;)

BikesOnline and first MTB

Post is to cover a couple things

How has the experience purchasing from BikesOnline? Looking for any reviews from purchasers utilizing the site within the last 6 months.

Looking to buy my first MTB and I have settled on a full suspension bike. Budget of <$3000.

I am a beginner/novice rider with some BMX background riding mostly green and blue trails with an occasional trip to a bike park. Looking for a well rounded bike and a good warranty.

I have looked into the Siskiu T9 but just would like to hear other recommendations or affirmations that may be out there!

Can I bring my bike to the bike park

I recently got a canyon nueron 5 as my first mountain bike and I’ve been having fun riding it around on the local trails and on some medium sized jumps. I was wondering if, in the spring I could bring my bike to highland mountain bike park which I live around an hour away from. Do you guys think that it will be too hard on the bike or will I be fine? If my bike can handle it I might go maybe once or twice a month.

servicing a cavitated fox float x2

I got a used 2019 fox float x2 for a good deal on ebay and I never used this type of suspension before so i didn’t know why it was making a weird noise, so I kept ridding it like that until i noticed it was sagging a little too much on long bike rides. my question is it worth servicing it for 200$ from fox or just sell it for parts and get another one? mind you i bought it for $260 from ebay.

Magura brake pads 8s vs 9s difference?

What's the difference between these two brake pads? It appears that the 9s pads are slightly cheaper than the 8s pads. Why is that? Both seem to have four contact points touching the rotor. I have a Magura MT5-E brake at the front, and both pads are compatible with it.

Looking for breathable chest and back suggestions for trail/enduro with lots of climbing.

Looking to up my protection from just knee, elbow and FF. Took a really bad spill this summer and lucky to still be walking. Finally recovered enough to start riding again. Overwhelmed by all of the protection options. Just wondering what others suggest or don’t recommend.

I’ve been riding for over 20 years and a crash this bad was rare. Just have 3 kids now to go home to so looking to limit potential down times.

Fox 38 grip 2 tuning

New to adjustable suspension and I’m working on tuning in a fox 38 (170mm travel) with grip 2 damper.

I followed the fox instructions for PSI/sag (they recommend starting with 15-20%). I had a bit of trouble measuring sag consistently but I’m now pretty sure I have it at 15% as a starting point, which I’m aware is on the firmer side of the recommendation.

I followed the recommended compression and rebound settings for my weight (165lb base, so prob 170-180lb with riding clothes/shoes, and kitted up for longer rides with water, snacks, spare tube etc all in a backpack) - I utilised the 170-180lb rider weight recommendations (LSR 6, HSR 5, LSC 10, HSC 5).

I’ve taken the bike out on a couple of janky rocky downhill blue trails, where there aren’t big drops but a lot of small-medium rocks and roots, and I feel like I’m taking a lot of impact through my hands and wrists - so the shocks feel somewhat harsh, I think, although I’m not 100% sure what to realistically expect.

After a decent amount of downhill over this sort of small-medium bump terrain, I checked my o-ring and it looks like I used a max of 115mm travel out of 170mm. I’m thinking this is probably about right as I’d want some in reserve for bigger hits?

Two questions I guess:

  1. Am I right to think that I should want some travel left unused in this scenario? I.e. that it’s good I’m not using full travel on smaller bump downhill terrain?
  2. If I’m going to tweak one setting at a time to see if I can get a slightly more plush feeling over this sort of terrain, where should I start? I could reduce PSI to increase sag towards the 20%, or am I better to start looking at HSC or HSR first?

Thanks!

What’s your thought on this video format?

I like it but it does feel like there is a lot of visual clutter.

The pros for me: I can see the trail, the body movement, and I like to compare the two videos side by side

The cons: I not know where to look, my eyes switch between the two videos.

Curious to see what other people think.

Tire selection help

Hey all. I'm here looking for suggestions on tires. I'm running a full sus Chisel with 130mm travel front 110mm rear.

I run mostly hardpack, sometimes damp hardpack. Usually dry and dusty. Some tech, some jumps, some steep climbs, some short steep descents, mostly flat and fast.

I have a Ground Control T5 on the front and a Fast Trak Control T5 on the rear 28psi both (tubed for now).

When I'm climbing I lose traction in the rear and just spin ruts.

I haven't noticed any issues in the front.

Other than the spinning on climbs the rear seems to be fine

Suggestions?

Magura MT7 keep dragging

First... I know, there are plenty of posts regarding this topic, but I could not find any solution yet :(

I just upgrade the brakes on my Enduro with a new Set of Magura MT7 Pro with Sport 8.S pads and MDR-P 203mm in the rear and 220mm in the front.

After I put everything together, I have bleeded the brakes, mobilized the pistons, pushed them back, but no matter what I do, the brakes keep dragging quite significantly. Now I have had them for about 30km on my bike and I am happy with the power, but the dragging is super annoying. When I look with a flashlight into the caliber, I don't see even a slight gap between the pads and the rotor, so I have no idea how to fix this. As already mentioned, I have pushed the pistons all the way back and their movement is fine, but it seems this is just a complete design error...

are there may other pads, which are a little more slim or does anybody have experience with 1.95mm rotors? Any other ideas, before I replace these with some XTRs?

Lyrik Ultimate 3.1 vs Zeb Ultimate 3.1

I’m not a pro. It’s my first full suspension bike, and second mtb. I’m from Ukraine, and got my first MTB (hardtail) in November 2021. And then war started so I didn’t have proper time for a ride, just a lot of hard working. This year I got my first fs bike, because I always wanted one.

It is merida one forty and In stock it has marzocci z2 150mm and deluxe select+ 143mm. I would like to upgrade it in the future if I have a chance to 160mm front and rear, but not sure what to get.

As I understand Lyrik is highly capable fork and probably will fit my style and skill level but zeb just look sick with those thick legs. Like impressive piece of manufacturing. I’am not a small guy, now I’m 100kg (bulking) and later it will be like 92-93 after cut. So what can be downsides to have a zeb. Is this stiffness too much and will be Lyrik more plush and comfortable.

Z2 is probably more then enough for me now but I just like all this things so maybe would like to buy some happiness.

And also is it a big difference between 2.1 and 3.1 charger? Because 2.1 sometimes on sale

Canyon Spectral CF7, Specialized Stumpjumper 15, Gaint Trance x 27.5

A little preface. 35 M 5'10, 185 My father in law is a local MTB legend. Has been riding before I was born and single handedly built the majority of my small indiana cities single track. We also have 8 acres of private trails and a small park. We frequent trips to Marquette Michigan. In the market for a bike. My two young sons are little rippers already (on balance bikes) my 4 year old does things some adults won't. I want to bring them up in the sport, but I have 0 single track miles. I'm not new to biking, and am pretty active. Wanting to choose an all around trail bike, with an option for some small park rides. Plan to attach a kids ride shotgun to bring my 2 yr old along with my 4 year old on his 14 inch KRS. FIL has always ridden specialized and encourages me to get a SJ. However I'm leaning towards the Canyon. Both the specialized and Canyon would be purchased new, and the giant trance x is used/local.

how do you feel about riding alone?

We all do it to some extent and I think we all know life gets in the way.  About to go into my 40s and much of my old social network has dissipated into domestic life or people withdrawing from higher risk riding due to injury.  I’ve had the injuries myself but have not had the kids….and I’m finding myself still progressing and loving the super spicy business more than ever.  I’ve caught myself worrying that I’m blowing it or something is wrong with me because I’m not in a well established crew.  I’ve always got some kind of agenda to connect more with others about riding, whether it is showing up to group rides or trail work events, helping others progress in their riding, or trying to link up with newer friends who ride at my level.  

I ride with others a decent amount, but alone a lot.  I’m also a pretty hardcore explorer and it often surprises people what I’ll go do solo.  I hit people up, and if everyone bails, I just go anyway.  And a lot of times I find that I have the most steady fun doing it alone—no stopping unless it makes sense, no performance anxiety, longer experiences of flow on sustained DHs.  I definitely think about the safety aspect, leave detailed trip plans when riding alone, and use the Garmin incident alert thing (which SUCKS when you stop to inspect a feature and it gives you police sirens….but I live with it) and other wilderness skills and practices honed over the years in other sports.

I guess I feel pretty good about it overall and I love our sport so much.  But I also notice it is a recurrent theme that comes up for me over and over, so I thought I would come and see if you all have anything to say about the topic.

Sometimes when I write contemplative posts like this I get these “you do you” comments.  Which is fine, and I’m already “doing me,” but also seeking to get outside of my own head.  I just hope I’m being clear that I’m reaching out to see if there are others of you who have an experience like me, just because I don’t know that many people like me in my personal life that I can talk to about it.  And I’m curious about other perspectives, not looking for some answer…
