Here's my Haro!!
It's a Subvert HT5 27.5+ bike! So far, It's been a fun ride. Much more nimble than a traditional fat bike, I love how much cushion the "plus" ride gives it- almost like full suspension!!
Things I've done so far:
1: Tubeless conversion!! The bike comes with pretty cheap tubes that were HEAVY!!! Throwing in some stems and sealant saved me over a POUND PER WHEEL!!! And of course, I don't have to worry about pinch flats anymore
2: Saddle- I was definitely not a fan of the stock saddle. Luckily, I kept the Specialized Toupe from my old bike. Much more comfortable, and saved more weight.. hahaha!!!
3: Dropper post- It's has internally routed cables, so I installed a KS-Lev dropper. The bike has a TON of room in the cockpit, so it's nice being able to really use that real-estate with the seat down!
4: Handlebars- It comes with a fairly heavy Ritchey bar. I installed a Raceface SixC carbon bar. I originally did this for weight and a little more width, but have also noticed that I can feel more feedback from the front end, which was desperately needed with the big tires.
Issues so far-
1: The HT5 is the mid-level Subvert. While it doesn't have entry level stuff like the HT3, it still used lots of in-house branded stuff. One item was the Pivit rear hub laced up with the WTB rims. On my very first ride, I was doing some park bench hop-ups, and had to put some pressure through the cranks on some agressive climb-up. There was a sudden "BANG", and then I couldn't freewheel any longer. Disassembly revealed that I broke two out of three Pawls, and cracked the freehub body!!! Haro warrantied the hub, and let me pay a small charge to upgrade to a Shimano XT Hub.
2: The HT5 comes with an FSA Comet crankset. This was an item I was already looking to upgrade because of chainring compatibility. On my old bike, I had started running an Absolute Black ring, and think a plus bike could really benefit from that technology. NOBODY makes a replacement chainring for the FSA cranks. On my third long distance ride, I ran into an issue 10 miles from the car. The Crank bolt on the non-drive side started working loose. Normally not a problem, but it takes a 10mm hex wrench to tighten it up!! I was able to limp it about halfway back before it fell off completely, then I did some "scooting" and one footed pedaling to go the rest of the way. Reading online, this is a common problem, and one that FSA has addressed by including thread-locker with their new cranksets!! This is the first time I've felt the need to put lock-tite on a crankbolt, but I assure you that's going to happen when the new bolt shows up.
Other than those two issues, the bike so far has been a terrific ride, and I plan on building a set of 29" wheels to swap out for long distance stuff!!!!
