Hi, I'm just getting back into riding a bike (I'm 32 and haven't ridden one in ages). I recently picked up a hybrid and made sure the sizing was correct at an LBS here in Korea. I'm a foreigner and don't speak Korean so it was hard to articulate on everything, he gave me a thumbs up saying good after making some adjustments when I bought it. He measured my leg, the angle my leg was making when I was on the bike and the peddle was all the way down and moved the saddle (how exactly I don't remember) but seemed to know what he was doing.
After a few rides I felt great, but then once I started increasing to longer rides like 50km or so (original rides were about half) I started feeling sore wrists and numbness in my hands. After one ride my hands were so weak I couldn't open a ketchup packet the next day and I didn't ride for a week as that's how long it took to make a full recovery. Clearly something was wrong I needed to address.
I figured as I getting tired I was slumping forward a bit putting a crush of pressure on my hands while also bending my wrists too much and possibly squeezing too hard. My bike has a standard handle bar and the seat is a few inches above the bars, so it's not a cruiser style at all. I've also made sure to maintain at least a slight elbow bend.
I bought some padded cycling gloves and Giant Connect Ergo Max Plus (that's a mouthful) grips and positioned them so my wrists would have a very slight bend and utilize the bar ends from time to time as well go one or no-handed often while stretching my wrists out. I'm now down from days of agony to about a day of mild numbness to recover. It still doesn't seem fully fixed and I can still feel like there's too much weight going forward onto my wrists and hands. I also lowered the saddle about an inch and a half and that seems to have relieved a little bit of the pressure without making my legs feel too tired.
My question after all that (sorry for being long but I wanted to explain what measures I've taken). I think the next piece of the puzzle may be the saddle itself. The nose is in a neutral position (not up or down, right in the middle of where it could be set to) but there is room to bring it forward a good 1.5-2 inches as well as back the same amount.
Would moving it back be better to relieve stress from my hands as it's shifting my centre of mass further away from the handle bars or would moving it forward be better which would make me sit slightly more upright but not have to lean forward so much?
Thanks for taking the time to read this. Just trying to get this right so I don't cause any serious damage. I'd like to keep my rides to about 50km and do them 3-4x a week.
