I've got a 2013 Crosstrail sport disc, had some of the same issues with wrist pain and numbness at the beginning, right along with "the pain in the ass". The good news is that as you continue to ride your body adapts to your new form of exercise and most of the aches and pains go away - until next spring when you get your bike out after winter...

I was dealing with numbness in my finger tips after a longer ride even with a set of moderately padded gloves, I purchased a set of Ergon GP5 ergonomic grips with bar ends and ALL of my hand issues were alleviated, they work just as designed and are definitely worth the money.

I also experimented with varying tire inflation to find a good ride and what the head guy at the LBS where I bought my bike said proved to be true, he said that for my weight, 195 lbs, set the pressure at 75-80 psi and you'll be good for most situations. This is with the stock tires that come on the Crosstrail, the Specialized Trigger 700x38C, the sidewall rating for these is 75-100 psi. I also tried setting them at 95 psi on one ride where I was strictly on smooth pavement, along with the shock being locked, and the ride felt good and fast enough to satisfy my need for speed, I was heading down hill at easily 25 mph. But for most of my riding where I'm on trails of mixed surface I keep them at 80 psi and it works well, I'm quite pleased with the Specialized Triggers and will replace with the same them when the time comes to do so, if you do a bit of research on bike tires you'll find that you want a bit of grip for trails and firm but smooth tread for hard surfaces. The Triggers are designated as a cyclo-cross tire, this is what Specialized says about them in their own literature: "The Trigger rolls fast on asphalt, hard-pack and gravel paths. Ideally for those looking to get the most out of a smooth, fast cyclo-cross course. This tire rolls great on and off road." If you need any further proof of this tires ability, it comes stock on the new 2015 Crux Disc from Specialized, which is a fast cyclo-cross bike, check it out on their site.

I also replaced the stock seat with another from Specialized that was a bit wider, 175mm instead of the stock 155mm, it made a big difference "in the end", sorry, just had to say that...lol!

...hope this helps you out with your new bike, if you look around on the internet you'll find lots of very happy Crosstrail riders, its easily the best bike I've ever had. If I had gone with a bike that didn't have a suspension fork it would have been the Sirrus Sport Disc, but with my bad back and carpal tunnel wrists I wanted the front end to soak up some of the bumps, and it has certainly done the job very well.

cheers, enjoy your bike...
