How to Calculate Chain Length

Hi, I'm new here. Just need some help right now for my grandson's Shocker 20 bike. The cable holder has come loose at the gripper handle and having trouble getting it back in. Any suggestions or where to get another 7 speed shifter for his bike? Thanks a lot. Sorry for not filling in any other "newbe" message, I'm currently baby sitting my other grandchild . That probably explains it all. 2...

I've read other threads and lots of info online, and I'm still stuck. My son is unable to shift the gears on his new 6-gear bike. We tried adjusting the derailer to release some tension and tinkered with adjustments here and there, and nothing seems to be working. Is there anything that we can do? I really want him to be able to shift his own gears. Going uphill today we had to stop several t...

I have just started hearing horrendous noises when pedalling my 7 week old Trek Powerfly 4 ebike. The sound is worse than clicking and clunking and I can’t tell exactly where it is coming from. So have uploaded a video here: https://youtu.be/G3X2tLHk4Bk. Has anyone had similar or know what if could be? I’ve not heard these types of noises before....

I'm in my 60's now and just want to putz around the neighborhood. In order to make the bike more comfortable I put a super big seat on it and 12" high handlebars. It's my Lazy-Boy on whe...

Hello everyone. After many winter rides, my 29er MTB began to throw out creaking sounds last week. It's nothing too loud, just a gentle yet annoying creak that happens on every other stroke but not constantly. Could it simply be the case of pedals (I have clipless Shimano MTB pedals) being "tired" and not the bottom bracket? Where should I look first?...

Hey guys I was recommended to post here to see if I could get any additional opinions. Would be great if you guys could help me out. Images: https://imgur.com/a/HvH98By I bought a second-hand carbon bike that looked mostly fine on inspection but when I took it apart to put in the car I noticed that the carbon around the dropouts might've been cracked? This is my first time seeing these 'enclos...

Hi... I bought 2 second hand wheels for my Gary Fisher bike.. The rear wheel came with a new 8 speed cassette marked... Shimano Hypergluide HG. After reading the spec. list of the bike it lists the chain as Shimano CN-IG51, 1/2 x 3/32" ..and the front gear chain as SR XCC-150 42/34/24 crank.. The original cassette was SRAM PG830 11-32 8spd My question ...is the new cassette OK with the original c...

I adjusted my front gear according to materials I read and watched on the Internet. Hanging the bike off the ground, fd works alright and shifting was seamless. Now I take a ride, flat ground, shifting front gear was good. Downhill was also perfectly alright with changing gear. When I went uphill even on a gentle slope, gear won't upshift; downshift was alright. I am on a triple chainring. When g...

I have a single speed kona unit with a formula dc52 hub (only single speed drive) and was wondering if anyone knew what freehub bodies were compatible so I can switch is to more then just a single. I would prefer not to have to buy a whole new wheel or rebuilding with a new hub. Thanks...

Hi Guys, I would appreciate some advice on choosing the right chain for a new singlespeed freewheel 16T. I have a Campagnolo crankset that is 1/8" and use Izumi chain of the same width. I'm currently on Sturmey Archer 17T 1/8" freewheel but I'd like to upgrade to 16T. All the quality 16T freewheels I found are made for 3/32" chains for example Box Buzz. Halo Clickster can supposedly accept 3/32 o...

Hello, Ive just had my over 30 year old rockhopper serviced and its as good as new. Almost! Repair shop - where i bought it 6 years ago and have been great servicing it - say the chain is very worn and will be almost impossible to replace. Its a six speed. Would this be true? I'm not grumbling as its been a great bike but at the same time seems a shame to ditch it for want of a chain. Appreciate a...
