I just bought a set of new, wider handlebars for my old (2002) Stumpjumper hard tail. My old set-up were 580mm bars (ugh, righ?) with a 90mm stem.
With the new bars I have to buy a new stem, because my old stem doesn’t fit the 31mm-diameter handlebars. Would you recommend I go with another 90mm stem with the wider bars, or drop it down to 70mm? I see the new Stumpys all have 100mm stems, but they’re also 29ers. I’m just not sure about this bike as it has pretty aggressive geometry. I don’t want to make the bike too twitchy.
First off, I love your stuff and am really enjoying what your books and Pump Up the Base have done to my riding. Now to the question, my wife is a light roadie/triathlete who is willing to step up her game and ride in the woods. I bought her a Specialized Rumor for Christmas, sweet rig, and am pumped to get her in the woods. She has ample fitness, but minimal handling skills. Since her biggest fear is falling and getting hurt, I figured some drills would help give her the much needed confidence to feel more comfortable in the woods. If you only get to pick three drills for a newbie to the woods what would they be? Given you wrote the book, it’s on my bookshelf with your autograph in it, I knew you would be able to hit this one out of the park so my wife can add “single track slayer” and “Riding” with a capital “R” to her list without undue injury.
(p.s. my favorites are your figure eight drills and slow tight turns that work on track stands)
I have been building a pump track today from your Welcome to Pump Track Nation instructions and it is going great except for this one corner. It is a 180 turn and I enter the turn at about 10 to 15 mph but I exit the turn going 1 mph and I can almost not make it up the roller. The turn is about 6 feet from the enter to exit, it isn’t very tall and when I am in the turn my bars are close to the ground. Can I gain more speed out of the turn if I build it taller. I have little trouble making the turn but it slows me down and all the other berms I gain speed and they are taller. Or would I just have to change the berm?
I realize how busy you are, but if you have a chance to check this out I’d love your feedback. There’s a new roller here at Santos in FL that I tried today. It felt great, was just dropping in slowly to test it out. On the drops I “felt” like my weight was in the right place. I tried to be heavy on the pedals and I could swear my hands were light on the grips.
Yet the picture and video suggest otherwise. If I draw a line up through my bottom bracket, almost all of my body looks to be forward of it. Yikes! So while this “felt” good it looks like it would have not been so good had the drop been longer. So on a steep drop like this what am I supposed to be feeling? Should I be getting back further than I think?
So if weather is just terrible and I am confined to the trainer for days or weeks at a time what would be better…? Stick to two Pump Up the Base workouts a week plus some level 2 time on the trainer or would it be ok to hit PUTB 3 times in a week?
I started lifting again for the first time in 6 months (I am naturally a spinner a.k.a. I am weak) the same time I started PUTB so the first couple of workouts (shoot even walking) were difficult but things are starting to feel better now. Thursday I got to the first B workout where you break it up with different cadences. I think that was easier than sustained effort because my brain (maybe weaker than my legs) was occupied. Did week 3 Day A today, it was pretty good too even though I lifted in the morning. Now if the trails here get dry I can get strong and learn to lay off the brakes on my recently converted single speed! May you have sunny skies and dry trails.
Hi Lee !
I am now in week 4 of your awesome Pump Up the Base program. For the last couple of years i’ve got some concern about target heart rates, that gets me confused. I am 46 so my 85% heart rate should be around 148bpm ( 220-46X85/100). But here’s the thing, at this heart rate i can sing “we are the champion” at full volume and i can spin that for days, barely sweating. I’ve followed you guide lines, and shoot for an effort that let me talk only in short sentence, and that bring my heart rate value around 162bpm.Wich is more like what i am used to. That value is around 95% of my maximum HR for my age ! that gets me nervous, am i pushing too hard ? I’ve been ridding for 25 years and feel better than ever, i ain’t no world class athlete but not definitely not your average forty something guy either. Any thoughts ?
Talking about bike-maths (Galileo would have built sick rhythm sections): when you manual-pump a roller, should the force be directed vertically (to increase your weight as you suggest in Mastering Mountain Bike Skills), or perpendicularly to the backside (so that all the energy is used to push off the ground)?
Provided that our aim is to get as much speed as possible. This issue has been niggling me for a long time…
I bought Pump Up the Base a couple weeks back. I am currently in week 2 and am enjoying the workouts very much.
I have a question—I’m doing my best to drop my heel and then point my toes at the bottom of the pedal stroke. I’m getting a feel for that circular motion, rather than mashing. I can’t do it every time, but I’m getting better.
My question is this: I’m feeling this in my calves quite a bit. Is that normal? I would think it is to some extent, but I know I don’t want to overdo it and all my power to be coming from the calves—they’re too small a muscle group and not connected enough to the core.
Any insight you have on this—if you have the time, of course—would be appreciated.
First of all, thank you for writing a great book. I’ve read Welcome to Pump track Nation several times and have been measuring out my pump track and started thinking about draining. In fact, I might have developed a problem. I’m beginning to wish it rained dirt, and every flat yard I see I ask, why no pump track?
My big question is, on the long return side (circled and labeled #1) up to my berms I will have to pump up hill (maybe a 10% grade, I haven’t measured it yet). What is the optimum pump size and spacing for going up hill? Should they be taller and closer, smaller and closer….
Another thing that you could perhaps comment on is making a “switch” spot to reverse direction. What would that look like at the location circled and labeled #2?
Thanks for you advise. I would like to build once and get it right.
Reading your book on MTB skills and have just taken the plunge and swapped out my Stumpy Elite 26 inched with a Stump Comp Evo 29er (arrives next week).
Thing is we have a nice pumptrack near us and i still want to ride it with my two boys.
It got me thinking that there’s going to be some differences now that i’m on a 140mm travel 29er! Any suggestions would be welcome – I’m guessing I can’t be the only person in this situation
