I thought some of you may like to read my half-assed long term Trek Session 10 review.
I originally ordered the Session 10 before it was released. I had talked to my sales rep and got some details and had an order place for my rig. I was pretty happy with my previous Session 77 but wanted something a bit more slack and race oriented than the Session 77. I had a pretty decent relationship with my previous Trek dealings so I felt pretty comfortable ordering something that hadn't been completely finalized yet.
The bike arrived late, no big deal. The first big dilemma was that the frame was out of spec. The main pivot was out of alignment and forced the bearing to line up incorrectly. Trek promptly sent a replacement swing arm. The swing arm wasn't the issue it was the main pivot of the main frame. It took 4 main triangles to get the pivot right, and a 5th frame to get the pivot correct and not have 6 tons of slag in the seat tube.
I eventually got the bike together and loved it for downhill right away. The frame was incredibly plush over everything. It was slack enough to find myself moving the dropouts to provide a steeper head angle. There wasn't a significant amount of pedal bob, it was efficient and I liked it.
At the time I got the bike I had just started racing the Sport class and didn't find myself needing a big 38tooth chain ring that the bike came with, so I slapped on the 32 tooth ring and rode it to work, at races and on some cross country rides.
My riding has improved and I can't ride with anything less than a 36t on any of my bikes now or I spin out too quickly. I slapped a 36t back on the Session and noticed a HUGE difference in the pedaling. It was still efficient in terms of not activating the suspension. However, the bike feels extremely sluggish trying to pedal in anything higher than 5th gear. This was frustrating for me and I spend most of my time in 6-9th gear. You really can't tell once your cooking at a good speed which is nice, but trying to throw cranks in out of corners takes a lot more effort than it should. I eventually got used to it and just let it be.
My suspension makes a nice honking sound on any hits as the swing arms aren't completely straight which slightly bent my shock shaft causing the spring to rub alongside the shock body.
The overall ride of the bike is still really nice. Plush, easy to flick around despite weighing in a 40.5lbs which is 4lbs heavier than my Foes race bike. The adjustable geometry is a nice feature. For those wanting something more freeride oriented the steeper head angle and higher bottom bracket settings are perfect. For speed, the slack head angle and low bottom bracket are just that, low(14" bottom bracket) and slack.
There are some obvious problems with the frame and were clearly missed by those at Trek. The main issue than got me was that riding in anything other than completely dry conditions would fill the linkage and force the bike further and further into the travel. I fixed the problem by creating an inner tube fender than keeps the mud from being thrown directly into the linkage. I talked to Trek about this numerous time and each time the tech would say to put a shock boot over the shock to prevent it. Obviously he either wasn't paying attention to what I was showing and explaining or just didn't care.
The upper guide pulley, I feel, needs to be moved either to the pivot point or above the pivot point. As it sits right now it feels like the pivot forces the swing arm to lift further into the travel.
The geometry listed for the large size is WAY off. The top tube on the large is listed as 24.4" my top tube is 22" with a 23" effective top tube length. The wheelbase is 46.5"!
There frame is quite limiting as far as parts selection goes. I absolutely despise that the dropouts are 8" disc specific. I usually run a 6" or 7" rotor out back, the 8" just feels like way too much. Typical chain guide like the E-13 SRS that comes with it doesn't work very well with the frame. There's along going around the pivot area. In order to rotate the guide to the point that the SRS back plate would be out of the way up the upper chain torque pulley the ISCG tabs would need to be rotated on the bottom bracket. I haven't tried too many guides but the SRS, LG1, and MRP G2 do not work well.
Trek also did some weird things with my frame, I got 4 different bolt lengths for the 6 dropout bolts I have.
The Session 10 is currently residing as my spare downhill bike and current winter downhill bike. The Session 10 will likely never be my primary downhill bike again, but I can't see myself selling it in the future.
