Others, well, YMMV Cheers Before gravel bikes were 'invented'/became popular the crossbike was the way to go for off road riding if you didn't want to ride a sluggish ATB. Because of the UCI limitation for cross bikes the choice of tyres was very limited. Now with the gravel bikes the choice is huge. Lou I'm not quite sure what you mean by limited. The cross bikes I've had all would take 32 mm tires and if you use any larger you end up with the same sluggishness as an MTB. That is the limitation I am talking about. The sluggishness of a MTB comes from all the suspension **** not from the tires. Off road riding of course. I have a local course with short uphill stretches of perhaps 100 meters of 24% or more loose rock. NO cross bike will go up those but I could get 7/8ths of the way to the top before carrying them the rest of the way. I did manage to go all the way to the top with a full suspension bike but they are very heavy on the front end and you don't have to worry about them lifting a front wheel. The shorter 20% I would ride over. The downhill sections are 30% and more in sections and 32 mm tires are too much traction. That is dangerous to try and do more than try to slow yourself for the next hairpin turn. The idea is to wait for a flatter section and cram on the brakes to slow you for the next steep section. One particularly nasty area was only 40 meters long but covered entirely with cross hatched rain ruts and 40%. The idea was to hit that fast enough that you got through it and onto the flat before you lost control. With a full suspension you just rode through it at any speed you wanted to go. But climbing I would run away from MTB's. Especially full suspension models which are so heavy. I'm told that the very top end are no heavier than a cross bike but I would have to see them to believe it. I see people with 36 or even 42 mm tires on cross bikes but I'm sure that they don't ride any real off-road. That is what I have on my crossbike 42 mm rear, 35 in front to prevent snake bites goining over roots. I do ride real off road. All the trails my friends need a ATB for I manage with my cross bike running 46/36 chainrings and 12/32 cassette. They only have to get out of my way because I have to maintain a certain momentum. They can't with their ridiculous small gears and the fact they have to be seated because of the suspension. I sold both my ATB's. Lou |

Others, well, YMMV Cheers You are not alone in that analysis: http://www.yellowjersey.org/3rmt.html Tire availability aside there was a reason that MTB's went to 29" (700c). 26" tires stick in places that the larger diameter simply rolls over. I didn't understand '29' bikes (700x54) at all until we did a custom Gunnar for a Special Forces operator some 16 years ago. A muscular six and a half feet of rider looks all wrong on anything 26-inch. 700x54 is very proportional for big guys. That said, our culture is plagued by trendiness. I roll my eyes when short women come in with 13" frame '29' bikes, seat all the way down and handlebars way out there someplace beyond her hands. "It's the latest thing" offsets reason all too often. Well, trends ae a problem but not for riders that know what they're doing. Isn't the 27.5 really a 250b size? That is for more effective sizing for smaller people. |

I've come up behind a lot of MTB's and tried to ride their speed and simply could not. At near 2 mph with a cadence of 80 like these people are doing the suspension doesn't really bounce much. |
