Trek 8.3 DS seat experience
I've had my 8.3 for nearly a month now and besides the rack I got on the day of purchase the only mods I've done are Ergon GC3's and a computer. I've been mostly riding on our decrepid farm land flat roads and have been on our community forest trail system once. The bike was the best fit when I was test driving them but having not been riding much in the past 20 years when I took it out for much longer runs, 5 to 10 miles, I started noticing the usual things, sore butt, uncomfortable hands ( the ergons help a bunch) and experimented with different seat heights. I was sure after a few weeks that I needed a new seat and was eyeing a Serfas dorado but didn't pull the trigger. I went on my longest ride yesterday, 16 miles and tried one thing different. I moved the seat back about a half inch and what a difference. No soreness at all in my rear end and the same for my hands. The bar ends really help to vary my grip. I had resisted moving the seat back as I thought it would put more pressure on my hands but there must have been something in the new geometry that just clicked. I'm glad I didn't run out and get a new seat to fix my sore but when it seems to be more of a fitment issue.I'll stick with the stock cheap Bontrager seat for now
I'll report back when I get some longer rides under my belt. This bike does great out on the open road and felt just fine in the forest as well!
actually setback increase, and a shorter higher stem shifts weight off your hands.
It's amazing how much seemingly minor seat adjustments can do. I was having issues with my 8.3 with hand numbness and discovered I was sliding forward on the seat and the issue came from pushing back against that. I adjusted the seat more nose up and that issue was resolved, bit I had other issues with the amount of nose up.
I ended up trying a Brooks saddle, which I really enjoy and am glad I got, but it only slightly helped. For me the only solution was a two bolt seatpost. The single bolt that came with the bike didn't have fine enough tilt adjustment for my body on the bike. Knowing what I know now my issues could have been solved without the Brooks, but as I said I do like how it feels as well.
