I finally took it out for a ride today.

Image


Keep in mind I'm coming off of a 1988 Rock Hopper Comp to this, so there's a bit of a difference to what I'm used to.

First of all, the bike is complete overkill for my skill/fitness level. But I knew that going in.

I rode this trail a few years ago on my 1988 Rockhopper Comp. So my baseline is a 30+ year old bike I've ridden "off road" one time in the past 25 years.

And since i'm not a pro blogger or anything I'll just toss out some misc thoughts on it.

I like disk brakes. A lot. That said, these do feel a little squishy to me but my comparison there are numerous Ducatis with top of the line Brembos, so I'm probably not being realistic on what bicycle brakes can feel like. I wish they had less travel before biting and a firmer feel once they do. I had zero issues with the function of them, it was just the feel that wasn't optimum. I'm not complaining so much as commenting, they're fine. I don't see a need to upgrade them any time soon. THAT said... I did already buy a floating front rotor. ZERO reason I need it. I just wanted it. It's a motorcycle thing.

The seat. I ordered a new one last weekend before I had even ridden the bike, a WTB Speed I found on clearance for around $20. About three miles into the ride today I was thinking the stock seat needed an adjustment maybe, but it wasn't bad. Maybe I didn't need the new seat? At six miles in I was thinking yeah, this thing needs to be adjusted. Angle the front down further? Maybe it's a skoosh too high? At seven miles I was thinking get me off this fooking thing it's horrible. Needs to be adjusted for sure and even then I'll try the new seat as soon as it shows up. Issue wasn't pressure on my sit bones or whatever they're called, it was pressure further forward from that.

The suspension. My first bike with suspension. FLASHBACK - I rode motocross bikes as a kid back in the early 70s. Then I didn't ride them for about 20 years. Then I bought one and went riding. Bopping through the woods there was a little ditch we had to cross. I stood up and expected a shock. Hit the ditch. Felt nothing. What the??? Holy cow, modern suspensions work. Flash forward to today. I'm cruising down a hill, got more speed than I was expecting, got a little more air off a bump than I was expecting. I was expecting a bit of a jolt on the landing. Felt nothing. It was like I had been softly set back down on the trail. No bounce, no bottoming, just a little whomp and on with the show, nothing to see here. Tee hee hee... I guess the suspensions on these things are for real. When I got back to my Jeep I noticed I hadn't come anywhere near bottoming out either end, so I might try backing off the air pressure but no complaints about how either end felt. Yes, I'm a complete newb to suspensions on bicycles so take that with a grain of salt but still.

Tires. I've never ridden on tires like that before. I had the pressures set at 25 ft/27rr and liked the feel of them in slow climbs and going over rocks and roots. Lots of grip. I'm running stock tubes and see no reason to go tubeless given my lack of skill and the terrain around here.

Gearing/shifting. Ok, the shifting isn't world class. There are likely adjustaments that can be made but going down the cassette isn't as positive as it could be. Moving it up into lower gears while climbing was fine so no complaints there. None of it was bad enough I'd consider upgrading anything but I can see room for improvement there. And I did fumble with the shifter a few times. I'm not used to this dual trigger stuff, I'm old school.

I'm 5' 10" with shortish legs (Size 30 inseam on my Levis). The reach of the bike felt fine, I don't think I'd want it any shorter, but the dropper post may be too tall? It's down pretty much as low as it will go and if the new seat is taller than the stock one, that might not be low enough. I lowered it a bit with the dropper towards the end of my ride and may be looking for a way to reduce the dropper's travel at somepoint to get the seat just a tad lower. All of that said I'd be curious to ride a medium size frame to confirm my thoughts on the reach.

Pedals - old habits die hard. I found myself feeling for toe clips. When I put my feet on the pedals I would slide them on from the back, and slide them backwards when I was getting off. I was wearing some Etnies Jameson BMX shoes and they stuck to the Chesters pretty well. By the end of the ride I was wondering if the soles could be a little stiffer though. Or maybe it was just me being worn out.

That's about it for the bike. I want to find a small bag to go under the top tube so I can cary some things. For today I put a bag under the seat but if I'm gogin to be using the dropper that's not a great place for one.

Only other thing I can think of is the Bryton Rider 450 I bought for it. Like I mentioned earlier, the mounts it came with are worthless for this bike so I 3D printed something that replaces the cap on the stem. That worked fine so no more efforts will go into that. Other than that, it did what I expected it to do - recorded the ride. Turns out I should have set it up to do some navigation for me too, but that's another post... Spoiler alert - My ride included about 4 miles of "more difficult" terrain because apparently I can't read signs, and the bike didn't even flinch at a few things that would have upset my beloved Rockhopper.

Would the average full size water bottle fit under the shock? I know yt gives you their thirtmaster thing thats a touch smaller, but I'd swear I've seen people with regular full size bottles in there.

Also...would a bottle and cage fit in that storage mount? It looks like it'd be possible maybe.

I went to order mine last night and my discount code didn't work, so I emailed YT again. Waiting on them to get back with me.

I don't think I have any full size bottles around here anymore to check. The one they supply barely fits so I kinda doubt it.

I might have a cage I coudl try in teh storage mount but I'd have to look around for it. I found a bag at REI I thought might work but I thought I'd wait for the points for my latst purchase to show up. I can't find th ebag online though so I'll have to go back and see what the deal with that is.

In other news, I played around with Strava after posting that. I had no idea that Strava provided so much info on rides. The Bryton transfers the info automatically so it's easy to use... one more thing to spend time with I guess.
 
Man, you did this so much better than I did! I didn't realize the packing materials doubled as a stand for setup, etc.! I know it has a read me first doc, but just pulling stuff out of the box I didn't even think about that. Great job! :)

The bike is pretty spectacular. First new mountain bike I ever bought at age 62!

My debacle. I got it done, but the hard way. :)

I got a Bryton 450 bike computer and none of mounts included with it would fit the bike, so I 3D printed something. I ran through one or two ideas before I settled on a simple post that replaces the cap on the stem.

It's worked out fine for a whole 9 miles so far, so I'm calling it a success. It only uses one of the rubber rings that come with the Bryton to hold everything together, which may bother people with it's lack of redundancy but if that's an issue there is a tether that could be added. With the (wimpy) type of riding I do it's not a concern right now.

I plan to take it out again tomorrow. The seat is supposed to show up today so I'll be putting that on first. If it's any taller than the stock seat I'll be figuring out how to mod the dropper too. I also might install the new front rotor even though there is no real need to have a floater on there. The bike is already over kill for an older guy on the trails I'm on! But whatever. It's all for fun, right?

I don't have any normal size bottles to try but I did put a bottle cage under the top tube. The cage fits but you'd never get a bottle in there.

The new seat showed up today so I put that on. It does look a skoosh taller than the stock one, so I removed the plastic wiper gizmo on the dropper. It's split so it's pretty easy to get off of there, you don't even have to remove the post. It'll sit about 8mm lower with no wiper? Seems to have done the trick.
Image


May as well slap the rotor on there too. Getting it to not rub was a finicky process. I tried to do it with the bike sitting on the floor but it wasn't happening so I put it up in the stand and messed with it. Turns out one of the rotor buttons was barely kissing the mount. I thought I might have to shave a little off the mount but I played with it some more and found a spot where nothing hits. So yes, a Hope floating rotor will work with DB8 brakes. Barely, but it works.

Hmm... what else did I do to it today... Added a cadence sensor for the bike computer. Rotated the bars forward a touch, mounted a bag on top of the top tube, and changed the grips. Next up is to print out a bash guard. I tried one off of Thingiverse but it's for a 30t chainring. I figured I'd print it out to see how far off it was so I'd know how to tweak it for a 32t ring. It's close, I'll draw up a slightly bigger one and try again. I might even finally break out the "NylonX" carbon fiber reinforced nylon I bought a while back if I get ambitious.

@DezmoDog did the bike come with valve stems to convert to tubeless?
No it didn't.

EDIT: I just went and double checked. It came with reflectors, insert thingie bobs for the fork, frame grommets for where the cables enter, and what's this? Holy cow, it comes with different size shims for the dropper to adjust it's travel! I can replace the wiper and insert one of those instead. Cool...

LOL...glad I could help!

More 3D printed stuff. I remixed a bash guard so it'd work with a 32t chain ring. Nothing fancy but it might help. Excuse the fasteners, they're all I had around that would fit. The stl is on Thingiverse. This one was printed with carbon fiber infused PETG but I plan on printing another out of NylonX when I get the printer set up for it.

@DezmoDog I was reading on the Jeffsy FB group and they are saying that the bikes come with factory protection like Ride Wrap, thought the core 1 may not. Does yours have anything like that?

I was thinking of doing the base Ride Wrap kit, and I don't want to order it if it's not necessary.
There was no ride wrap included with mine.

I finally got around to adding a shim to the dropper to lower the seat. I had already removed a rubber wiper/seal thing to get the seat lower but it still needed a few mm drop to be where I wanted it. There are three lengths of shims included so I could have added the wiper dohickey back into the equation but I didn't really see the point, so I left it out. If you have the dropper raised up in the frame I can see where the rubber part might serve a purpose - but it you're doing that you don't need the post lower anyway.

The point is, the dropper is adjustable. If you look at everything that comes with the bike it's kind of obvious but if you're the type who just kind of wings it you might miss it. There are instructions in the bag with the shims that go over the installation of the post (which you don't need to do) and how to add the shim.

It's easy to do. The top of the post unscrews by hand, if it's not pressed down onto the clamp too tight. Before I loosened the clamp and raised the post a little I couldn't get the top cap loose.

Once it's loose slide the cover up the post and the top shim in the photo will be there. Then add one of the three shims to lower the max height of the seat by that amount. It's the deal with the split in it that's already around the post in this shot.
Image


Now you need to slide the shim and the top hat dealie down into the post, which you won't be able to do if the seat is all the way. Press the dropper trigger, lower the seat a bit, and that will give you the room you need to slide it all in place. Then screw the top cap back down and you're good to go. The instructions on the booklet show the same thing and even use the technical terms for all the parts.

When I put mine back together I found that it wouldn't raise up the last 10mm or so without a little help. I loosened the seatpost clamp, raised the post in the frame just a bit so the top cap wasn't pressed against the clamp, and that solved it. Works like a champ and more comfy at the new (lower) height.

I'll end up removing it when I eventually try out some 160mm crank arms, but for now the fix was a lot easier than I first expected. Apparently I'm not special, adjusting the travel is common and doesn't require the custom work I was envisioning.

That color is great. I wish they would do better colors on the other builds.
I like the color of the core 2 and 3 also and would have been happy with them, but the other colors wouldn't have been my top choices. Nothing that would have kept me fomr buying the bike but I prefer the colors of the lower builds.
 
Nice ride, only going to suggest one thing. Clamp it on your seatpost in the stand, not the top tube. Hydro formed aluminum does not like to be clamped

Thanks for the heads up. I typically do clamp onto seatposts, except for when I'll be messing with the seat post. The bike is sitting rather loosely in the clamp when it's on the frame, more like cradled than clamped really... but point taken.

I hadn't really thought about how they form the frame tubes for these things. We used to hydroform parts for exhaust systems occassionally, I didn't even know you could do it with aluminum.
