Yup, the damping part is also super important! I could kind of go on for days about tyres, but the damping is an interesting part because it is part of what generates grip too. Rubber is viscoelastic so has 2 modes of generating grip - the first is your regular mechanical friction between the surfaces, but the second is hysteretic grip which is where the rubber deforming sideways creates an opposing force in the material as it squishes. This is the "damping" part, and kind of similar to how a damper resists compression forces in a shock. So a bit...

I also think a lot of tyres are too square for 30mm rims, the new conti's have such a square tread, it only slows you down on climbs, I personally favour a rounder profile, gives better grip when cornering, maximizing traction when the bike is perfectly upright isn't a priority

In my opinion an underrated part of tyre talk is matching tyre and wheel stiffness, soft tyres and stiff rims means burping and ripping off carcases, as the tyre moves and deforms but the rim tracks true in the terrain. Stiff tyres flexy rims means lack of grip. Its about finding the balance. The PB review of the new Berd wheels is an interesting one, for a long time I've thought wheels are too stiff, and that we are trying to "out strengthen" the common issues of dents, burping etc. Making a wheel/tyre combo stiffer and stiffer isn't a solution...

Honestly I was nervous switching from Maxxis to Conti Kyrptotal on my Enduro/park bike because i pedal the first couple of laps up the hill before the lift/shuttle opens. The Conti's in Supersoft/Dh casing roll much better than the Maxxis MGrip/DH casing The conti's in Supersoft dont feel as soft as the maxxgrip however that doesnt feel like the case on trail, they perform much the same with the contis feeling better as IMO The excellent job on the casing makes them lighter and for whatever reason give a better carcass feel. I Can run about 2 psi lower with...

The biggest factor affecting speed on a MTB (climbing and on the flats) is the tires. Not the bike weight or suspension travel. Most modern bikes are efficient enough that if you're seated the whole time, the rolling speed difference between a 100mm race bike and 160mm trail bike, given the same tires and wheels will be about the same, given the same power output. If the trail is very steep up or down, you will see the lighter bike pull a little time back on the climb and the enduro rig pull back time on the descent. It's very...

I like this thread as I’m a big tire nerd. test idea for vital- test loop (timed climb and descent) on: enduro bike with enduro tires enduro bike with xc tires xc bike with xc tires Xc bike with enduro tires id love to know where speed % comes from. Use a power meter to equalize climbing effort.

This is good topic I don't think gets enough attention. I'm slowly gathering data on it but its going to take a while to test everything! A few things I've noticed - Tyres are spring, and air pressure changes the spring rate but they are not an air spring! ie the gas pressure doesn't increase much when they compress. The casing construction being energised by that pressure is what turns them in to a "spring" Pressure + width affects the contact patch and pressure + casing changes the spring rate so these 2 need to be balanced to get the...

The Enduro has been my daily driver for many years and as of today, I can't think of anything else I would like to ride. It is incredibly versatile. I build it with reliable components (XTR, Fox), nothing exotic, electronic, or lavish just a really good functional tool. I love to ride it but I think its lines and esthetic are horrible.. many better-looking bikes out there. In my case, it is the GOAT of modern bikes. It's a rational bike to buy if you are unsponsored 30-40 years old.. Sure, there have been more iconic or successful bikes in...

The Enduro rides fantastic but there are far too many cracked frames to even consider it as the GOAT. And these are cracked frames from mild-mannered consumers too, mind you. I personally know of 3 people who aren't even in the top 20 of their categories who have cracked frames.

Also, the Specialized Enduro does that thing where the frame actually has some pretty bad engineering flaws causing it to crack at the head tube under heavy load. And at the BB. And the seat tube. And the upper rocker link. Seriously, never saw a frame with that many weak spots. But when Specialized eventually manages to figure out how to build reliable bikes, I'm sure the Enduro would be a decent performer.

Stumpy sorry, enduro might be 2nd

Choosing the greatest bike of all time based on performance is a pointless task as it is impossible for anyone to have ridden a large enough sample size in the period of relevance to make such a declaration. From my perspective in order for a bike to qualify it must meet a combination of criteria that make it iconic and representative of its specific genera of mountain biking. This should include performance (represented by race results/market acceptance), impact on the direction of niche and the desire from the intended market. In my opinion the Enduro doesn’t meet the level required...

Can't really argue with that. Each gen of the enduro has been rad (excl '99) vs. market competition since it came out ages and ages ago. For me the GOAT mtb is always the one you currently own if it has brakes and suspension that work properly on a regular basis.

Clip in grips man

https://www.cyclingabout.com/speed-difference-testing-gearbox-systems/ Rohloff is pretty close to a derailleur!

SRAM has had webinars on it. The product is being sent to shops. It was supposed to be launched in the fall with the new Specialized UDH Crux. Seems like they have abandoned the typical embargo because it's being shown everywhere. Shimano has DI2 XTR and DI2 1x GRX dropping as well. Great time to be a consumer of bikes and components.

They are the exact same frames. Cannondale pulled them out of a closet in Connecticut and painted them. At least they have a paint shop in America…

Or it could be because they look cool and moto and everyone is now discussing them and leads to sales? Devils advocate I know. But often they change product just to have something new to sell, not because it results in tangible performance benefits.

In moto, the primary reason is the offset change in the clamps. You are right, the floating bushing is marginally free'd up but the selling point is the offset adjustment which makes a noticeable difference. For MTB, I'm struggling to find anything other than bling and lighter than a conventional clamp perhaps.
