Dude came into the shop, probably 5'8, bought an XL full sus mountain bike because he liked the color, he asked me to lower the seat post... which was a dropper post that was fully compressed and inserted fully into the seat tube, 😂 I said impossible... he still bought it, he didnt want the medium that was a different color 😂
To correct Owen, beeswax is actually better at sticking to metal and mixing with oils than paraffins, hence not needing specific additives. The main if not the only reason against beeswax is cost and inability for manufacturers to put 10x margin on it. Also its composition is not that easy to control at industrial scale. And we don't want to sell/buy ocassionally products of brand A under a name and at a price of brand B or god forbid C.
Beeswax is also very different, chemically speaking. While paraffin wax is just a bunch of long chain hydrocarbons (only carbon and hydrogen), beeswax is a biological product which is made of molecules similar to fats (I'mmtalking about esters). Those esters cannot be controlled, can degrade easily when subjected to the stresses of a chain, and can react in unpredictable ways that can make very big differences between batches. Also, it is much softer, so it can be more easily squeezed out of a chain under load.
@@edymarin7781 exactly, you are putting perspective behind better adhesion (oxygen group helps with polarization) and problems with industrial scale (those esthers, of which are actually only a handful, are relatively stable and rather belong to fatty alcohols - not like typical trigliceride fats - but still require extra control in distillation if you obtain beeswax naturally or harder to synthesize compared to paraffins if you want to go all way petrochemically). As per softness, it's not that bad, while paraffins live on a wide scale and those found in drip-on solutions solidify to even softer butter-like consistensy. Immersion formulations are harder though, but also have tendency towards embrittlement what is not optimal too.
Immersive waxing is fantastic and much less of a faff overall than having to periodicly degrease and clean a whole drivetrain. Just give the chain a quick rinse in hot water in a jar, then put it in the wax pot, and switch it on. Come back once its melted and you have a clean chain that looks like new. Bee's wax however is probably not the best wax to be using. I'm no expert on bee's wax but I'm under the impression its a fairly soft wax compared with a food grade paraffin wax which is the recommendation for trying immersive waxing on a budget. A softer wax will be less good at resisting absorbsion of grit and dirt so may become more abrasive and could gunk up the drivetrain, where as a harder wax will flake off rather than build up.
Even the namebrand chain waxes are not that expensive if you consider how little of it is used with each waxing, and how much you save compared to wet lubes. And yes, it is totally not a faff. If you ride in only dry conditions, just a cloth with some isoprolyl alcohol is enough to clean tge dust off of the chain before putting it in the wax
Weren't designed to work together? All mineral oil brakes are designed under same umbrella of standards, governing seal materials and clearances. Differences are marginal and still within the standards. One can even do a TRPrickstuff and fill it with Caterpillar steering hydraulic fluid, would still work.
within the same frame size, handlebar fit also makes a huge difference. with good fitting bars I can lap bike park top to bottom nonstop, with bad ones I had to stop after each section of trail because my lower back hurt so bad. played around with handlebar width and rise and got rid of riding pains. I needed something that put me more upright
Height is only part of the equation, I am 6’1 with a 36” inseam, my nephew is 6’6 with a 32” inseam. Long legs and short torso or long torso and shorter legs 🤷♂️ go to a reputable bike shop and they will fit you out properly
About the tyre question, i believe specialized already tried with a bead lock , they were great too , it was called the iron curtain beadlock ,and it was great if a bit heavy , cant remember the model of tyre , it was some time ago 😂
Yes well remembered - I had a set of the Specialized DH tires with the extra bead lip - made setting up V-brakes trickier - and harder to mount - I feel there were from 1997 or 98? Cheers Owen
Anna about the rockgarden issue isn't not about the tire, it's my rims that get eaten up! I'm missing chunks of aluminium and carbon 😂 Immersive wax is not for roadies only and it's just PTFE powder, pure parrafin wax and pure paraffin oil. + The manufacturer secret sauce (additives yes) but often there's not much to it it's about the ingredients ratio..
So use a narrower rim then! 2,3" on a 30mm is a rather square fit. Also, it's mountainbiking: scratches and dents happen. And car tyres don't have a dedicated lip to protect the rim, it's just their construction to hold shape.
A lot of lubricants are switching away from PTFE for a lot of reasons (most important being the environmental impact, but the efficiency is also a part of that) to better stuff, like molibdenum or tungsten disulfide.
@@edymarin7781 efficiency and cost were the reasons MoS2 was replaced with PTFE (it has higher shear strength and therefore shows better efficiency in high stress applications, also better thermal and chemical resistance which is unnecessary in cycling). WS2 is quite similar to MoS2 in that sense. So it's all about evironment. Ideal would be graphite (and there are such lubes), but it is an absolute mess practically impossible to clean.
120-120 is enough for most occasional bikepark riders in the flatter countries. Don't waste money and weight (and materials) for (on 🍟) stuff you don't need. I. e. don't buy a bulldozer when all you need is a shovel and a medium sized, 10 liter/litre 🍟 bucket :) Get better brakes and better wheels & tires (tyres 🍟) first.
#askgmbntech Hi Anna!! Talking about your video about wheels compliance. Starting from already knowing to true wheels. Would be safe or reasonable to play with spoke tension so you can get more compliance or stiffness on your wheelset? Nothing crazy obviously
I use Turtle wax paste on a new chain it makes the chain last longer and keeps it from rusting. I ride everyday all weather all terrain. Trust me it works.
#gmbntech please could you do a Vittoria tyre comparison video. For example, I live in the Forest of Dean and know when it dries up I can swap my DHR 2 for a dissector on the rear to get a bit more rolling speed. I want to swap brands just because there's more to life than maxxis but don't know where to begin with Vittoria and really fancy trying them out as heard great things about the Mazza. What tyre combo's would you use for DH/Enduro/trail from the Vittoria range? I ride a privateer 141. Thanks, the content is great!
For the leaky caliper guy - if it’s already out of warranty then it’s already out of warranty. If the pistons are leaking it’s irreparable without voiding warranty as Shimano don’t sell new pistons or piston seals Use whichever mineral oil you have or mix them .. remember you need to use a Magura hose and a Shimano barb and olive. Depending on which version of deore you have (age) it may be BH90 or BH59 Barb/olive
@@stephenlord599 yes, as long as the flow ratio from the master cylinder is close to correct for the new calliper (as Anna mentioned), it ought to work...
On ergonomics and bike fit: Do you have to care about seat tube angle? Except for riding back uphill to do another run, I am NEVER on my seat. Also, the seat position is wholly adjustable, so really, why care when I can just move the seat? =) Thanks! #AskGMBNTech
For most rides I spend like half an hour riding up and 5 mins down so I'm on the seat the vast majority of rides. Tbh, I don't think iv ever seen a trail ride where people are standing more than sitting unless you are running shuttles.
#AskGMBNTech; I have the problem of bad arthritis in my right hand, making long rides painful. My left hand is thankfully free of the ailment, which makes me wonder if it possible to get shifters for the left-hand side of the bike? I have a SRAM UDX 1x12 on my Fezzari LaSal Peak. Thanks in advance!
I'm looking at a full suspension mtn bike for my son. He is currently riding an Orbea Lauffy (large). He is on the overlap for most manufacturers Large/Medium at 178cm tall but is quite light at 54.5kg. He has begun XC and Enduro racing with his high school. Would a 170Fr/Rr enduro be over sprung for his weight? Thanks
Paraffin wax = oil derived Ceramic wax = silicon derived polymer I know people are trying to be eco conscious but there's a reason we don't use bee's wax, hemp, or corn oil to lube a bike chain. Unless you just really like replacing components... Which were also mined and have been manufactured probably using the things your trying to avoid in the process material removal. There's reducing your carbon footprint and then there's cutting your feet off. 😂 I promise... Your chain lube is doing less harm to the environment than watching this video on the Internet. 🤦
Mineral oil is graded on how distilled they are, which is dependant on the contaminants are in the oil. So there will be slight differences in how the oils react under pressure and heat, it's best to stick to what each company recommends 🤙
#ASKGMBNTECH Love the video. Just built my first bike from scratch from just a Trek frame. It was a very satisfying learning experience. But my question is as I want to build another bike from components leftover. I am really in between sizes so opted for a small frame as for the trails with drops etc felt like it would give me more confidence. But now scanning the 2nd hand market for frames should I be going for a medium sized frame as there seems more medium frame choices for creating a MTB/road invention with rigid fork as I am really in-between sizes. Thanks guys
#askgmbntech I have an older Specialised S-works M5 hardtail. 26” wheels on Hope pro 2 hubs. Can I upgrade it to 27.5” wheels. Would I need different hubs or could I use my existing Hopes?

#AskGMBNTech Is there much of a difference between downhill bike and trail/enduro bike sizes? I have a Polygon Siskiu in a small and a Specialized Demo in S2 (small), the polygon fits me perfectly but the demo feels like way too much bike on the trail even though they're the same size, are dh bikes naturally bigger or did I get the wrong size bike lol?
