Too small mtn bike = shoulder/back issues...?

Since DS has taken over my mountain bike I'm borrowing a friend's TINY Salsa Ala Carte until we can manage to invest in a bike for me (I'm really eyeballing a 14"/XS Salsa El Mariachi 29er). It's an XXS/12.5" frame. I am just shy of 5'4". She is about my height (maybe a half inch or so shorter), but tends to like really small frames.

We have the saddle maxed-out and I could still use it a hair taller. That's not the big issue. When I ride it I feel sort of like I'm on a clown bike. I assume a 14-15" frame would be ideal for me (30" inseam, average torso/arms). My Cannondale mtn bike is only an XS (I think the seatpost is just under 14") and is also small for me, but less so. We'd have our DS ride the Salsa, but it's a LOT more bike than my Cannondale. Everything about it is faster and it's a handful. The Cannondale is much more forgiving.

Anyhow...DS and I rode 11.5 miles on Sat. Most of those miles were on the paved rail trail to get out to some singletrack about 4 miles away. Ever since then my back has been p!ssed! I am not really prone to back issues. Sometimes I will sleep funny (or a cat will steal my pillow) and wake with a wonky neck or shoulders, but this has moved from the middle of my back and outwards and downwards. I'm suspecting the tiny bike is to blame, though I know my core could be stronger (I've been doing 1-2 core workouts/week for about a month, now).

Sounds small. Why not take your bike back and let your son ride the small bike, assuming he's smaller than you?

He is smaller than me...and from reading it appears that a lot of folks his size bought this identical bike or people bought it for kids about his age/size. It's just way too much bike (new it cost twice what my bike was full retail). Everything on it's fast, the steering and brakes are much less forgiving, and it's really light compared to my bike. It's a handful for me. But it's becoming tempting, since it's sorta breaking me.

Can your son just borrow the bike that you are borrowing? I mean, if it's being used by you, and it would be better for him, why not just switch? When you are able, get yourself a new bike and then give him yours, and give the borrowed bike back.

I've suggested this to my DH, but he's pretty tentative about the thought of the rugrat on this bike. It rolls MUCH faster down hills and the brakes are extremely grabby. It's a recipe for an endo (it's definitely harder for me to handle this bike with my limited skills). The steering is super sensitive, too. My bike is so perfect for a noob, since it's heavier and everything about it is more sluggish and low-end. But it may be worth a try.

I agree that a too small of a bike can cause back problems, having a bike that fits properly--as you already know--is very important.

Also take in consideration that mountain biking uses your muscles differently than road riding. Whenever I take newbies out for trail rides they often complain about back and shoulder pain--usually from using those muscles in a new way. Part of that is their core muscles aren't conditioned to that style of riding. It's typical for new riders to use the death grip on the handlebars—nerves causing them to tense up. That tension causes stress on the muscles (especially shoulders and back).

Another cause of back pain is a bad pedal stroke--pulling too much on the upswing. It's common for a lot of us that use clipless pedals to adapt that type of pedal stroke. How many times have I been told to pull up on the the pedal! when climbing? A million times. But that can actually be really bad for your back. Here is a good blog post on pedal stroke.

One more common cause for back pain: tight hips and leg muscles. Here are some stretching tips.

Welcome to the world of trail riding!!! :D

All good things to know and think about, thanks LW! I didn't know about the pedaling thing...I'll definitely want to keep that in mind in the future. I've thought about the benefits of flat pedals off-road. I need to learn to keep my feet from flying off the pedals when I hit bumps, though. :p

I'm thinking it's probably the bike size, though. Last week when we went out and I was on my larger Cdale I didn't have any unreasonable pains (rode 65 miles on my road bike the following day), aside from my bruises. :o

Sat. was a MUCH easier ride (mostly on the rail trail, just a little bit of easy and really slow singletrack), but my back was angry for 3 days after that. That's the longest time I've been on that bike, so I suspect that that's the issue. The pain was concentrated in the middle of my back, not my lower back or arms (though it started to sort of radiate outwards after a day or so). Until Sat. I never did more than 4-5 miles on the weds. night rides, so I was never on that teeny bike long enough to really stress those mid-back/shoulderblade muscles.

I think we are going to try DS on the tiny Salsa. It will probably be a really perfect fit for him, since I think he's right around 5'.

If we weren't so sandy around here I probably could, but the brakes are not at all good for stopping well (they're good for CX races, but steep hills with loose stuff at the bottom, less so) and I think I'd really miss the front suspension. It's great for 2-track gravel and packed sand roads, though!

Zoom, this doesn't relate directly to this thread, but it occurred to me that you, your husband and son might really enjoy the Midwest Women's Mountain Bike Clinic. It's typically held in mid-June in Brown County State Park, in south-central Indiana. As the name suggests, it's a clinic for women of all skill levels, but there's also a kid's clinic. The trails in the park are excellent and would likely appeal to your husband. Prices are reasonable, and camping in the park is also pretty cheap. It'd be a great place to show off your new 29er! :D

Just thought I'd put a bug in your ear!

Oh, that bug is already there rooting around! If I didn't do the clinic we're at least talking about doing Spring Break there, next year! We love the idea of a road trip combined with mountain biking! :D

Cool. I hope you can attend.

Just be forewarned that the trails in Brown County are often not rideable in the spring, depending on how rainy it is. If the last couple of years are any guide, things don't start drying out until mid to late May. This year, we had a really wet spring followed by an incredibly dry summer (until last night, the last measurable amount of rain we'd gotten at my house was in the second week in May).

Ooh, that's a good point! Hmm...we will have to take that into consideration. You guys have had weather patterns like ours, this year.

It's hard to win around here. By the time the trails are good and dry, it's also good and hot. June is often a good bet, but you never know. We had 28 days in July over 90 degrees. That's a new record. Last Saturday was the first pleasant day in a while. I'd almost forgotten what it feels like.

Yeah, same here. A week ago I made it out to a really nice singletrack park about an hour away for the first time in months. I couldn't believe how dry and loose the trails were. Lots of ruts that I don't remember. Corners were really churned-up and kinda scary. While we were there a tree fell (lots of new trees down). The drought is making trees just fall on a still day--scary! :eek:

Yeah; the downed trees really freak me out. A horseback rider got killed last month in Brown County when a tree fell on her. That hit a little too close to home. We rode last week at the park that had gotten a fair amount of rain the day and night before. It was still soupy in parts that morning, but as the trail dried, it was nice to ride on something slightly tacky. The trails in Brown County are crazy dry and crazy fast at the moment.

I'd really glad you're taking a renewed shine to mtbing. I recall you saying you didn't really enjoy it earlier in the summer. Having gotten into it myself over the past two summers, I can say that it's quickly become my favorite thing to do on two wheels. I'm having a blast. I still have lots to learn and will consider the clinic next year. Unless and until I learn to consistently get my front wheel up, I'll be pegged as a beginner. That's not an issue, but I really need to tackle that skill. It's my biggest mental block at the moment.

When we were there earlier this month we regularly heard trees falling. We had one fall in our campsite the day before our arrival! And a large branch fell on our truck. :(

Yeah, I have LOTS of skills I need to master. But I am finding that road riding is starting to get kind of boring to me. I never thought that would happen, but after nearly 3 years I'm not enjoying riding the roads near me as much as I once did--especially when I'm riding solo. DH told me this would happen, and at first I thought he was crazy, but it turns out he's right. He's always right. I hate that! :p

I hope your truck wasn't damaged.

I'm sorry I didn't end up hooking up with you during your visit. We were out there the day after the holiday (the day your rode with Catrin) and had every intention of looking for you after we did the North Tower Loop, but I felt so unwell on the trail that day thanks to the oppressive heat. I nearly threw up. So, as soon as we finished, we just went straight home. I hope you had a good time, notwithstanding the heat.
