How to Replace Handlebar Grips

After 6,000 or so touring miles, the bottom bracket on my Trek 920 broke. Does anyone know what is compatible for a replacement? If I were to choose to replace the entire drive train, what would be compatible? Finally, if I were to replace the drive train, should I go with a 1x for gravel?...

Hello, I'm running an Apex setup on my gravel bike, 40T front to 11-42T back. Could I swap in an 11-46T Shimano cassette (11-speed all round)? Just considering options, as my Apex 11 speed cranks don't go lower than 40T...

Hello, all! Just joined this forum to post this, as I feel like I've looked everywhere online and am going nuts; where would one acquire a replacement for a back-right 26' wheel for a Schwinn Meridian Comfort trike? Mine took a pretty severe hit and suffered multiple broken spokes, and I'm not the most mechanically inclined nor financially comfortable. I figured it wouldn't be that difficult, but...

Hello. I have a Mavic XM 319 rear wheel with a 10 speed Shimano/SRAM free hub which I want to convert to 11 speed. Which replacement free hub do I need and will it fit/work? Understand Mavic uses a particular freehub/pawls arrangement so I want to get it right....

My dad gave me his Scalpel 29 4 2013 and I've been working to get it to a good riding state since it sat unused for a long time and the challenge I'm struggling with is disc brakes rubbing. I learned to gravity bleed the brakes, and in the process I cleaned the bike, the calipers and equipped it with new shimano disc rotors and pads (my dad had uberbike ones, they were a little rusted and I wante...

The gearing is cool but these hubs suck for beach work, one little splash of salt water and they ar...

Hello, I'm new here, my dad has given me his 2013 Scalpel 29 4 since he no longer rides and I'm gradually learning how to maintain it because it feels like a bike well worth learning repairs and maintenance for. I'm slowly figuring out what it does and doesn't need to have maintained, what has and hasn't stayed in good condition in the time since he used it. While doing some unrelated work (takin...

Hi all, I just got a Schwinn Meridian Trike and went on a nice short uneventful ride today - it worked well - and then after doing something else for a bit, I got back on the bike and the pedals wouldnt turn the rear 2 wheels. Both chains seem to be attached and turning, but for some reason the front chain isn’t moving the rear 2 wheels. I don’t understand what could’ve possibly happened. D...

Hi ... the Sheldon bike calculator does not address changing a 3 speed hub input gear that I could find. Example: 34t crank - 24t input 3 speed - 22t output 3 speed - 28t cassette. I'm getting nowhere trying to juggle 4 gears. Can someone help this tired old biker? Thanks, Zene...

I have Shimano BB -UN72 mm110. I’m sure it’s British thread. What is a compatible shimano part number....

Hi ... odd question, but is there any difference between rear adult trike wheel right or left wheel drive? All are right, but I have the keyway to do either. Not sure why right, must be a good reason. I tend to travel around town counterclockwise. Left drive seems as if it would be better. Thanks, Zene...

I have had a ViVi MT20 e-bike for over a year.I recently changed the worn out brake pads. With a fully charged battery, I rode on throttle only for about a mile. After that, the power went completely out. I turned the key on and off. The LED lights came back on. I twisted the throttle and went about 10 feet and the bike completely shut off.again. Any idea what might be the problem? Thank you!...

First post, be gentle. I'm in the process of converting a 2019(ish) Trek FX 2 Disc to a single speed. I'm using the DMR revolver kit in the back and up front I bought a Shimano Nexus FC-C6000 crankset. I bought it on eBay but I feel like it may be a European model because I never see it on US sites. I removed the derailers, changed the shifter/brake combos to just brakes (Shimano Sora) and re...

Hi guys. What are your thoughts on putting heavy viscosity oil on a freehub pawls? Would it work better than using grease?...

I bought this Vilano Hybrid in 2020 as my “old person’s Chinese Cheapie”. It was - (and is) - FAR from equaling the “serious” bikes that I owned back in the 1990’s. The first Trek I had was a gorgeous blue road bike - worthy of all the gawkers it inspired. My Klein Pro Race MTB was the finest all-round “terrain-chewing animal” I ever mounted. It never failed. It never said...
