To take up the slack, Trek routed the chain through not one but two idler pulleys. The result looks a little like a three-ring circus near the chain ring, but that added idler pulley allows the derailleur to do what it’s supposed to do, which is keep the bike shifting well.
I loved this bike off the bat because it felt nimble and fast and gave me the confidence to sail over a few steep lines that I normally avoid. On trail, I never felt the need to ride beyond level-two power, even on climbs, which added to its acoustic feel. The only place I could have used more of a boost was when riding home straight uphill on city street with a 13 percent grade.
After multiple subsequent tests, I felt the same joy with one caveat: There was a consistent and nagging rattle that sounded like a loose wheel, but I could never isolate the source of the noise, which likely indicates that it was internal and perhaps coming from the battery or a cable rattling in the downtube.
To give the Slash+ a more robust test, I passed it on to Samuel Hayden, a former collegiate gravity rider at Fort Lewis College in Durango, Colorado. After a 20-mile ride in mostly turbo mode on the double blacks of Piedmont (stuff I never ride), Hayden returned with a huge grin and with more than 65 percent battery power left in the tank.
On its weight and handling, Hayden reported that the Slash+ melded substantial power with a surprising lightweight build, noting it had a solid and reassuring connection with the trail and maintained stable flight during jumps.
His only major gripe? The 9.7 lacks a SRAM transmission, which tends to be more reliable for e-MTBs. But that problem is easily solvable, if you have an extra $4,000 on hand, by upgrading to the Slash+ 9.9 XO AXS T-Type.
