Is hardtail with good fork up on the front capable of chunky dh.and large jumps about.50 to 100feet
Are all SANTA CRUZ bikes made in U.S.A..??
I can’t afford a better fork than the stock suntour xct is it going to do the job #askgmbntech
#askgmbntech Dear Hell O’Tech! Do you recommend any lubricant/cleaning/conitioninig sprays for suspension and dropper seatpost stantions? Or just cleaning with soft cloth after each ride would suffice? Any knowledge about manufacturers warranty policies regarding such substances?
This episode helped A LOT! Thanks and keep it up 🙌
Somebody told me once that I should shift to the smallest pinion when I don’t use my bike for a longer period of time to relieve the pressure off the derailleur’s springs. Do the springs really wear out by staying in a bigger pinion?
Thanks for your Q&A – it’s great!
Does the new single crank cog system have more friction than older units, due to the clutch resistance. I have noticed since getting a latest spec bike i feel when i service it things don’t seem so smooth anymore. ie. takes more force to rotate the crank.
i got a cheap bike doody, the brand name is marin and it is from malaysia not california what i should do to upgrade it?
I did a red trail on a decathlon rockrider 2007/8 and was fine
For the longest time ive been having second thoughts as to whether i buy carbon or alloy, 27.5 or 29, trail or enduro. This video gave me the best insight. Thanks so much!
Alloy, 29er, trail bike, im coming for you!
hey #askgmbntech if I want to be able to ride xc trails but also go up to the mountains and ride enduro, what travel bike do you recommend?
#askgmbntech is it possible to put hope brake levers on slx shimano brakes
#ASKGMBNTECH I have a sr suntour 140mm fork and it is very stiff. Have changed the pressure and it is always stiff. Anyway to sort this out
I have seen in person and on videos carbon bikes taking fairly light hits and that cracks the frame, I think carbon frames are very over rated, and no we’re near as strong when you crash.
Nice explanations Doddy ! BTW, I changed the chainring after only 1 season (before worn out) to go AB-Oval and it was worth it. Climbing technical trails seems more rewarding now
#askgmbntech Hi. I have a Scott Spark 920. It’s a carbon framed bike. I bought it used. I noticed that the components are a mixture of SRAM and Shimano. Shifter and Crank are GX SRAM, whilst the brakes are SLX and the rear cassette is a Shimano. Upgrading to a new bike is very expensive and I was wondering what your advise would be for a good reliable upgrade for long marathon XC Sunday rides. We do 60/70kms on average . Many thanks. Tahir.
#askgmbntech hi doddy, i want to buy a new bike for longer trips (50-80km) and for a little shredding… I like the canyon neuron al 7.0 in large and would like to hear your thoughts on this bike.
Thanks and keep your awesome work!
#askgmbntech how do you remove volume spacers

With the way you guys love coasting down hill like you’re on an amusement park ride, your frame could be lead and you’d never notice.
#askgmbntech I am a mtb starter and it has been 3 months since i bought a cube aim pro xc starter level hardtail , i also shoved a rockshox recon rl 100 mm last month . Should i keep upgrading it with better wheels , bars and drivetrain , or should i buy another bike ? I ride lots of roots and rock gardens btw. Thanks in advance
#askgmbntech what frame protection, if any, do you and the guys at GMBN use? Considering how far I should go with frame protection.
Fox vs rockshox
Hi Doddy , I am buying a new bike, it has a fox fork , in one of your videos you gave a link to a rebound calculator based on your weight however that only works for RockShox forks is there an equivalent for fox forks ? Thanks #askgmbntech
#askgmbntech the next bike I want to get has suntor fork and shock (120mm travel) I was wandering weather that would be enough to go to bike parks such as 417. If not should I upgrade, but what to.
#Askgmbntech does is it really matter which way you put the rear shock? I’m think of upgrading mine thanks!
#askgmbntech great show! very informative does carbon wheels become weak over time? How long can you use it for?
I upgraded all picked from DNM back floater front 120mm travel DNM ! alloy aluminum 7500 frame frame hand made ! breaks hydrolic 27.5 Loud volt !
What do you think about Propain bikes? #askgmbntech
4:48 Doddy, I think the question was about floating brake calipers 🙂
#askgmbntech is the scott scale 980 a good beginner bike?
#askgmbntech Floating brake I first thought of floating brake calipers. Had one on my first MTB which was actually my dads. No idea what it was. But why aren’t there any floating brake calipers in the mtb industry while its the most common brake type in the automobile industry?
I will definitely go for an aluminium frame on my next mountain bike. I have broken two Lapierre carbon mountain bike frames. Worst bikes I have ever owned.
#askgmbntech Last Christmas I was given the promise of a new bike of my choosing. I live in the northern parts of Sweden and temperatures regularly drop beneath -20°C, and I love to be able to ride in the snow. I’m currently borrowing a 2015 Fuji Wendigo (on 26×4.7 Vee Bulldozers) fatbike for the first time and I must say that I’m loving it even though it’s a 17.5 frame and I need a 21.5er. Either way, no matter where I look I always seem to come back to the 2019 Trek Farley 5, a 27.5×4.5 fatbike. The thing is, I doubt I want to run a fully rigid fatbike in the summer. I’ve seen a lot of people talk about changing to 29+ wheels, both with and without adding a suspension fork, during the summer. Not only do they fit, but it won’t "compromise the geometry". Now, finally to my question. Do you think that changing to 29+ tires on a fatbike is a good idea, and what does the aforementioned quote mean?
Also, from what I’ve read, it’s not worth bothering with a suspension fork when it gets this cold, would you agree with that?
A little sidenote, I currently own a Merida Maroon Matts. I mostly do urban mountainbiking and commuting, but I’m getting into trail riding more and more. I should note that rolling resistance is not my biggest concern. The way I see it, it’s just more calories being burnt and I really need to loose a few extra kilos, gone from 99 to 86kg last year, I still have ways to go.
Also, excuse the mile long question. It’s my first time doing this.
#askgmbntech Hi I’m riding 2018 Spectral 8.0CF L. It has 140 mm rear travel. the 2019 Spectral has 150 mm rear travel. On 2019 Spectral the damper has 5mm more stroke. 2018 – 230x60mm, 2019 – 230×65 . Do you think I can put longer travel damper to upgrade my rear travel to 150mm?
#askgmbntech Hi Doddy, I’m starting with the Tech Channel first, since this is about the actual bikes. It would be fun and interesting if you put together an overall count of World Cup riders running 27.5 and count of 29ers, including privateers? Maybe for EWS too. Love the show and your passion! Cheers from the States.
#askgmbntech Hi Doddy love the show watch it everyday and has taught me lots about bike history. I have a question relating to broken spokes. I have a 26" rear wheel ( transition revolution 25), which is a Norco fluid lt2, a bike that spends most of its time riding park and jumping. In the last 3 months, I’ve had 5 or 6 broken spokes ( all at the j bend). I was wondering if there was anything you recommend doing to prevent spokes breaking, finally, it would be awesome and useful if you could do a video on how to replace spokes. Thx Arif Khan
Would you recommend using something like the Velosolo hub spacer kit to run a boost fork with a non boost frame/wheel? #askgmbntech #askgmbn
askgmbntech I can’t get off my xx1 cranks, it’s like seized, or should I remove the little 4 holed cap first ? And how ?
Can you put a fox 36 and an bigger shock on the back on a cannondale habit so you can have more travel so you can do bigger jumps and some downhilling
#askgmbntech Hi Doddy, i got a small problem with my 2008 RS Pike , its a 454 Dual Air, and what ever i do i feel like the fork its not stiff enough for me. I’m a big rider, 115kg , but i don’t know if that should be such a big problem to make my fork a lil bit more stiffer.
i went with a good spec aluminium bike rather than a low spec carbon bike.
I paid 2,6k euros for my mountainbike which is a lot of money for me. a similarly spec’d carbon bike would have cost me over a grand more
Hey doddy. At the moment I ride a Merida big seven 40 and I’m wanting to upgrade and I’ve been considering the new Marin san Quentin I ride a lot of easy trails and street riding and just thrashing around but I was wondering if the Marin will be a better bike to ride more aggressive trails and bigger jumps. What are your thoughts
I used to ride grade 5 tracks and hit 1.5m drops on a 100mm travel hardtail and it was fine, bike still running well to this day.
Hi gmbn I want to build a ebike with a 5 kw motor and a cvt but that is a lot of work so the question is if I should buy a ebik or build one? #askembn
Steel!! LOL, JK!
#askgmbntech for about £1500 should I buy an aggressive hardtail, full suspension or secondhand full suspension.Love the vids keep em coming !
I ride loads of reds and even black on an XC hardtail
Never would I go carbon.
