Does Mountain Bike Size Really Matter? | Blake & Doddy Switch Bikes!

Here on GMBN Tech we often talk about how much difference the correct size MTB can make to your riding experience, so today we thought we'd show you an exaggerated example. Doddy will be taking to the trails on Blake's size medium Canyon Strive, and Blake will be riding Doddy's XL Nukeproof Reactor. How do you think they will get on?

Actually this video is really good for ppl who want to re-enter the sport and are unsure about their size. Years ago it was really like: This is your size and that´s what you need to ride. You need to let em know: It´s ok to go a size up or down in your spectrum if it suits your riding style.

Great vid. I'm 5 foot 8 (172 cm) and have gone from medium hardtail 26 to large full sus Scott Genius 29'er. (it was too good a bargain to miss) it seemed huge at first but I soon got used to it and now I love the confidence it gives. Mind you I;m 55 and not into catching air, just long rides around the hills of Hayfield.

[@roof30]

5' 4" and I ride an XS Cannondale Trail 7 (27.5 wheels). Standover height on the S was just at my limit so I opted for the smaller frame. Love getting out on the trails on it.

[@jpg6482]

Loving the Easter vids - family viewing on Easter morning !

[@adanielweaver]

I'm 5'10 and my current full suss bike is a large with 475 reach. Feels pretty good but a little long. My HT is 450 and that feels perfect. I test rode a full suss at 450 and it felt just right too. I have also ridden my friends XL full suss and HT bikes for a laugh and its just like they said, fun in a straight line and fine for most climbing, but hard to turn as fast.

[@fenderbenderspecial]

I'm about 6' 1" and ride a large full sus and an XL hardtail. I've found the XL feels much more stable, even though it's the hardtail. It's a little harder to throw around than the large, but it's still fun. I think a large version of that frame would've fit me better, but it wasn't in stock!

[@dylan-5287]

6"3' xl. On my FS it's perfect sizing, wouldn't change a thing. On my hardtail though I've sometimes wondered if a L would have been better. It's more older geometry with a high top tube and I feel like it'd be more maneuverable that way, plus I can only fit a 100mm dropper on it vs easily a 150mm, possibly 180mm, on my FS.

[@avidpsychlist8129]

Maybe a suggestion for a second video along these lines. Given how difficult it is to get any bike now let alone one in your size, maybe a video on small alterations that can possibly allow you to go up one size or down one size and still be happy with your purchase. Thinking along the lines of 10mm longer or shorter stem, wider handlebar, shorter travel dropper post, etc. Even in non-Covid times, you can save a lot of money on end of season deals by getting the bike in stock and switching a couple things. My ex was able to get a great deal on a size medium (vs small, she's 5'-4") by getting a medium, shortening the stem by 10mm and shortening the handlebar by about 20mm. She loves it!

[@jaydenRayner]

I'm roughly 6 ft 3 and I am currently riding a XL Rocky Mountain Thunderbolt. I've tested out a medium frame in the past and I can safely say that my XL bike is a HUGE improvement.

[@Jdem9]

I have a YT capra large. Fits me just right like what it said on their sizing chart. It took me a while to get used to moving it because my older bike was a kona process medium. But with confidence and experimenting, i was able to move the bike just as good as my old bike.

[@dctruckguy]

One of my favorite British shows is Last of the summer wine. Doddy-Foggy, Blake -Compo, Neal- Clegg and Martin-Howard. I think you guys could weave this in to a story line.

[@mikes4163]

I'm 5'6½". Was torn between S & M as for most makes I fit either. But I eventually got a Trek and their sizing put me pretty solidly at M, so that's what I got with 29" wheels. At times I've felt it's a little big - eg. I struggle to lift the front wheel (I'm only 135lbs) - but as I mainly ride cross-country it seems to work OK. This video has reassured me that it is actually right for me/my needs. If I ever got to try and do tricks like Blake it might change, but that's not likely.

[@WildMidwest1]

Blake: “Have you got the champagne glasses in the back seat?” Doddy: “It’s got somethin’ on the back seat but it ain’t champagne.” ROTFL!!

[@simon__3919]

175cm and Small Voodoo Hoodoo frame for the playfulness. I had M size but switched to S as it felt like a tank to me. Still (after a year) I can not do what I want on it due to lack of strength (only in my head probably) or proper technique (in other's minds - and their are probably right =) ). Nice video - very chill and natural.

[@richruff7292]

Thought long and hard about this one when buying a frame for my dream build end of last year. I'm between 5ft11/6ft . Settled on a large full sus frame and I'm so glad I did. Nearly went for med but with a 35mm stem and no layback dropper the large is just about big enough. Did my first 50miler on the new bike yesterday, after a few shorter rides to get everything dialled after the lockdown build , and yeah definitely the right choice to go large.

[@fourocker]

5'8" on a size M Trek Roscoe, perfect fit for me, feels equally balanced climbing or descending and it's the recommended size for my height on Treks chart.

[@davelloyd8454]

Great vid guys. Accurate , informative and entertaining.

[@markbroad119]

[@mtbboy1993]

well done guys. this will show how it is to ride a too small or too big bike. you went really in depth on it.👌

[@JeffRevell]

I'm 6'5" and I ride an XL frame. I have also had to change the flat bars to something with a bit more of a rise to get me in a bit more upright and comfortable position. The real challenge is getting that long seat post so that the legs can get a good stretch and to keep the body forward over the cranks. It has smaller 27.5 wheels and I think I'm regretting not getting 29s but COVID limited my available choices so I'll enjoy this one for now until supply catches up with demand and I can move up.

[@kaseyburlingham2861]

I am 6' tall and ride an XL, being 200lbs bike feels easy to throw around but a size large with wider bars to make up for the shorter reach feels good as well. A reach between 460-480 is what I look for.

[@wizkidcyclist9968]

Thank you for a great video, This really simplifies the logic of bike fit. I have just started to ride about (4 months till date) and had I seen this video before hand, I would have made a better informed first purchase. Since I was just getting into the sport and there was a shortage of bikes during 2020, I bought a Polygon Cascade 3 Medium sized bike and I am about 179 cms. In about 15-20 days, I started to get pain in my palms, and specifically around my elbows. I tried adding a stem to increase the height and an upright position but that too didn't' help - on the contrary, elbow pain got worst. Tried saddle height adjustments and landed with pain in and around my lower back, knees. Finally, replaced the grips to ergonomic grips for some relief, but then longer rides > 40KM, just kept on getting more uncomfortable. Finally, after having read and watched many many videos on GMBN, GCN - I decided to replace my bike from a Medium to Large. I have placed an order but the shortage continues and so hopefully in a week or two - I should have an upgraded XC bike (Polygon Premier 5) and hopefully many fun trails in near future. Thank you once again!

[@erikd6124]

How did your new bike work out for your pains?

[@sgricey2214]

I am 5'10 i ride a medium full sus with 27.5 wheels for playtime and my HT is a large with 29 wheels, found it was better to go bigger on the hardtail for stability but do feel like a passenger at times on it but good for flat out speed. Perfect RAD for the full sus and RAD+ for the HT.

That being said, the xl is a big ol girl lol I feel really stable and more in the bike than on it if that makes sense. The only time I think about how a large would have been better is when im doing more Jib, trials stuff. I think an xxl would be way to big hands down. Hope this helps man happy trails!

I am between sizes and coming back to mtbing after 20 years I chose large for the stability. Might go Medium or M/L on my next one.

[@elrictdb]

I have a 2021 Whyte T-140 S V1 and I'm sized right smack between Medium and Large, I opted for medium as bikes tend to be longer than they were last year (current trend it seems) and because I wanted the dropper to be fully down for downhill and fully up for everything else (no wasted or missing mm at either end). There was also peer pressure and internet forum pressure to size down, rather than up...or more hits at least. Oh and as a bit of a noob MTBer, I thought the medium might be easier to 'unexpectedly dismount' from.

[@MILICEVIC87]

I'm 195cm, and I ride a xl frame with 29 inch tyres. A xxl wouldn't be too big for me, but I couldn't find any bike in that size. But I can't complain, the xl bike is fun to ride and I feel pretty conformtable on it. In comparison to my nearly 10 year old mtb, which have 26in. wheel size, this new one is a huge step forward for me.

I've just ordered a 2021 Ragley big al in a Large and was a little worried I may have gone in the wrong direction being right on the lower limits of a large and upper limits of a medium. this video has put some of my worries to bed, thank you very much guys! a perfectly timed video for me.

[@ch_chone]

I’m just over 5’9”, so 176cm, and I am always on the fence between a M or L in MTB’s and between a 54 or 56 in noodle bar bikes. I keep switching back and forth as I buy/sell bikes for different purposes but for now I’m pretty well set on a size L MTB with a tiny stem. It seems to split the difference between the good stuff of a larger frame without limiting body movement or making the cockpit feel gigantic.

[@lukewalchle8004]

Been waiting for this since February!

[@core-i7413]

I'm 5'9 and I go for the medium frame. It's maneuverable, it's a good length, and it's lighter than a large frame (every gram matters because it's an XC.)

I'm standing at 5 foot 10 and I'm riding a 26" size S bike. My seatpost is 400mm and I had to max it out. I also had to use a stem riser so my arms won't be too low. But I was confident in corners.

[@matt_acton-varian]

Going one size smaller on road bikes makes sense as geometry is not as affected very much especially with frame sizes differences being comparatively small and charts often specify an overlap. But off road, unless you are specifically buying a dirt jumper sounds very awkward indeed, especially with bigger changes between sizes in regards to the angles and reach.

[@carnicer78]

I'm exactly the same height as Blake. I have recently bought my first double sus MTB, which is an S size (I was aiming for an M size but as you know, there is supply shortage), with 29'' wheels. After 2 months riding it, I am still unconfident in some descents, and I miss my 27.5'' wheels. As Blake says, he prefers smaller wheels (27.5''). When I told my dealer about this (before watching this video) he said I should get used to 29'' wheels, but after watching it, now I know I should have the smaller ones.

[@pw7752]

Nice vid. I got myself an Orbea Occam recently and at 175cm I'm at the very end of their Medium sizing bracket, or 10cm into their Large bracket. I decided to go for the Large and so far it feels great. The guy at my LBS said he thought the bike's too big for me, but I honestly can't agree. Seems your vid backs up my experience. Cheers!

[@erikd6124]

Have you measured you rider area distance and so on? I'm 6 and might go for a M Occam. Saddle moved all the way back. I'm on a orbea laufey Large at the moment. Sagged it should be the same as an Occam orbea says

[@Poraqui]

Imagine my case back in 2007 when I bought my first "real" mountain bike and had no idea about anything regarding the sport. I solely trusted the bike shop guy for my purchase. I'm 179,5cm and it was customary to recommend an M size regardless of brand and geometry. But my M had just 390-400mm reach. No wonder why I never felt comfortable in that bike and progression was soo slow and scary.

[@pags1981]

Santa Cruz 5010 and Kona Process 167 were the perfect mix of playful and stable

[@BikeTripBro]

Im 5'5, always in between small/medium size. I always choose medium and put shorter stem and adjust the seat a bit forward. When its time to change bike, selling bike at medium size is faster than small in my experience.

[@jeffv.akaonsjeffke9865]

I'm 180cm and my Ghost M with reach of 432mm is a bit too small. I often sit on the very back end of my seat in the climbs. I like a bit smaller frame, but too small is not good. Hoppimg over to a santa cruz M with 450 reach will feel better. I believe in the RAD aproach theory: height in cm x 2.5 = perfect. A size L come often with a reach of 460-475, and that would stretch me out too much.

I have found that not all XL frames are created equally. I'm 6'5" and getting the geometry right for a comfortable ride can be a real challenge. I changed out my bars and stem to help out a bit and fine tune things. Adding a 35 degree raised bar helped quite a bit as my original bar was pretty flat and I was bent over too much. Back and neck pain are not welcome companions on a ride.

[@evanloudenback3700]

I'm 5' 11" and debated (longer than I should) weather to size up or down...the curse of being between sizes! haha I wound up going with a Large Nukeproof Scout 290 Comp - feels great! It's like having a monster truck to charge down trails, great at speed fun on climbs - happy I sized up.

You are not really inbetween size man, most brands have 5'8 or 5"9 inbetween M and L. Nuke do mark their bikes a bit bigger but they really don't make them any bigger than other brands, glad you went for L, it'll be defo too cramped on a M for you.

Great vid, I’m 5,11 and I ride an XL specialized levo turbo, just feel way more confident on the speedy down hills and find the up hill easier, only prob is I don’t get to use the dropper post.

same here bro

[@nichtDarkDiamond]

I am 170cm tall and ride a Jeffsy in size Large (460mm reach). It is a long Bike, but compared to all of the other brands I tried it ist the only long bike that is low enough to have a good saddle position. In bike shops I couldn't even sit on a bike with ~445mm reach because the saddle wouldn't go low enough. Thumbs up👍🏻for the great design work from YT. 🖤 I would like to try out a bit shorter stem - maybe 40 instead of 50mm - but it is pretty expensive and I need new Pedals first.

[@istillhavetenfingers8150]

I'm 5' 8" and I rode a Medium for most of my mtb life and loved how agile I am. Recently I switched to a Large and I've never been happier. Just faster, stable, and can climb much more now.

[@marcalvarez4890]

Thanks for the input. I am between small and medium on a XC bike. After a LOT of research i still cant decide, and keep going back and forth. Would you suggest a small with the standard stem, or a medium with a 1 inch shorter stem? Opinions? Thoughts?

[@mathewmccabe7175]

I’m 5’9 and used to ride large (sb130, revel rascal)... just got on a medium switchblade and never been happier. Terrain and ride style are everything.

[@All_the_bikes_are_cool]

5'11" always large frame... In current bikes 460-480mm reach... My previous bikes were around 410-440mm reach depends from application... Since I tried modern geo I can't imagine back to the past... Steep seat and long reach 🤩 ok slack headtube too 😎

[@hanswurst6864]

Blacke just looks so adorable on that big rig :)

[@mannylopez76]

🤣🤣🤣

[@ROCKNROAD4X4]

I bought a BMC four-stroke frame size was XS. I'm 5ft 8. The one of the techs came out and said he also rides an XS frame and he is just over 6ft. Also, my Mrs and I are both 5ft 8 yet she has long legs shorter body and I'm the opposite. Sizing of different manufacturers also changes the mix, so sizing up really is a case of testing not guessing.

[@rossmanning4863]

6’8” and 19 stone. Still waiting to try a bike too big for me 😀

[@The_RC_Dude]

Man, you are a GIANT!!!

[@sepg5084]

If you are tired of waiting, you can have a custom built frame.

[@cjcox1480]

Have you been around an XXL Nukeproof Giga yet?

[@Vikturus2k6]

I’m 6’7” 220lb, same thing. I like my xl hard tail but would love to try a full squishy xxl

[@rickgreenhalgh1357]

Bird do some really big bikes, their xl is huge.

[@markdavis8430]

Any day my legs are dead Smack on gmbn I'm soon feeling like putting some miles in! Thanks guy let's go!

[@chimps4gimps]

10:56 just what you want to hear from your mate when you lend them ANYTHING of yours 😂

[@RubenJFernandes]

hi, nice video as usual, currently have a Specialized Kenevo comp size S3 and i have 170cm before i had YT Jeffesy and was a Medium, for me its the right size, but on a hardtail i will go smaller.

[@wyatth6824]

I'm 6'2" (~188cm) and I have an XL hardtail with shorty stem and a large full sus. The HT is a cheapo and the full sus is old. I would love to have a chance to play with the sizing on a modern bike lol

[@kaedeschulz5422]

What an awedsome and funyy video🤣🤣🤣 I size biked by geometry numbers. I'm 1,72m tall and currently riding a size large that has a 442mm reach wich feels perfect to me.

[@marksandoval5361]

5'9" and I ride a size-XL with the seat adjusted full forward and a 35mm stem. However, my bike is 3 yo when geo had a shorter wheelbase. If I were buying a new bike, I would likely buy a size-L. I prefer the stability of longer wheelbase bikes.

[@FantomPhish]

I’m going to use RAD sizing guide on the next bike. So most likely going from a large to a medium..

[@RequiemDead]

According to all manufacturers sizing I should be a size small as I am 5'5", however my new bike is a 2021 Pivot Mach 6 in a Medium and it fits me perfectly. Now I question everything with sizing charts.

[@abhibhagat7767]

You are comfy with a 460mm reach?

[@Basement_CNC]

well thats a really creative, fun ( and probably stupid) video both of my absolut favorit presenters in one vid ( im nearly as tall as doddy , im a total tech nerd and i love blakes attitude and riding style)

[@koko-lores]

actually not that stupid when you need to decide if you want to size up or size down. Just a bit exaggerated ;)

[@user-fi3uu2ry8i]

176cm and I’m on the cusp of Medium and Large. Prefer the medium myself. The wife rides a small 27.5 and I’ve had a few turns and it can be quite fun on the downhill. Riding uphill sucks though.

[@DL180sx]

Im 183 or 6 Foot. I was right on the overlap in sizes between L and XL. I went with L and happy I did.

[@Streamlines]

To exaggerate the effects of how you shift your weight around on your bike, ride in wet weather / low grip situations. It will make it very clear. Currently riding a bike that is too small for me, and in the summer I didn't really notice because the grip was so good. I continued riding in the winter and it became very clear that I had issues building grip on the front and I had to really want to do it. And once I got grip on the front, I felt loose on the rear immediately. Also bike is twitchy through long turns and I feel cramped on climbs and jumps.

[@tofikhabie9193]

I’m 6’ and I ride a medium and It’s small for me but I like the range of movement that I have

[@aryanabhol5755]

Same here bro just add longer stem and a long length seatpost

[@rogeliopitti7120]

Same.....5' 11.5" in a Trek Roscoe 8 2019 medium size.....Stem 80 mm.

[@boots796]

I am 5'11" and often find myself in between a large and medium depending on manufacturer. I typically go for the large, I like the feel of a slighty larger bike rather than it being a tad small.

[@guol1806]

Same, but with modern geometry I find the M have the same reach that I’m used to and more maneuverable than the large.

[@SKNZ2727]

@@guol1806 Agreed, with my Evil insurgent I was lucky to attend a demo day and ride a medium and large. 5'10 and I opted for the medium as it just felt right.

[@danbuckel4648]

I’m 6’1 and ride a size medium mondraker. The reach is 478 though so a lot longer than most mediums and closer to most large frames from other makes

[@Windband1]

That's like Blake riding a Geometron! ;)
