- Singlespeed Help!
Hey ive just built up my first singlespeed. Got a problem when i put pressure on the cranks. It pedals fine but when i need to put a good bit of weight on the pedals it jumps! It feels its missing a gear that it doesnt have. Chain stays in place and is tight (using a superstar tensioner) Its not the freehub as ive swapped my wheels with my other bike, have tried to adjust the rear gear spacers but doesn’t make any difference.Posted 7 years ago
Possibly. You need to make sure that as many teeth on the rear sprocket are “wrapped” or engaged as possible, otherwise it may well slip.
Alternatively, have you checked the chain for stiff links?
Perhaps post a pic of the tensioner if you’re still having problems.Posted 7 years agokayak23Subscriber
Just as an aside, I found that those push up/down chain tensioners were a bit rubbish. Couldn’t get them to work very well, they took the chain away from the rear cog, plus they look ugly.
I found the neatest solution was instead to use an ISCG-mounted bottom roller guide for the front ring. You don’t have any of those problems and your chain is wrapped tight to both rings. It also looks a lot better imho. Only thing is you have to do it up through the gaps in your chainring in tension. Simple and rad.Posted 7 years ago
To the OP, are you mixing new and old chains and cogs? That could cause the problem.
To kayak23, I ran my first singlespeed with that system and got ‘tip of the month’ in MBUK for it. Only problem is that it doesn’t give a full links worth of adjustment so you have to be lucky with your combination of cog sizes and maybe change the chain earlier than you might otherwise.Posted 7 years ago
Thanks for all the responces.Posted 7 years ago
Ive had a look at it and im putting it down to the tensioner (superstar one that pushes the chain up) causing a lack of chain wrap. Does anyone know if the so called heavy duty tensioners on superstar will work?
I’m currently using a Gusset jobbie in push down configuration on a 32/16 drivetrain, there’s certainly a problem with chain wrap causing a bit of skip when you really torque it on a climb.
I think I might have to find a pull up tensioner or a BB mount one like kayak above, no ISCG tabs so BB mounter (probably a Blackspire stinger I expect) any thoughts Yall?Posted 7 years agoFreesterMember
Had a similar issue when I built my first singlespeed. It jumped when i put the power down.
I used a ‘push down’ tensioner. I just couldn’t get the chain tension right. It was either too loose and skipping. Or if I lost one more whole link it was WAY too tight.
In the end I bought and replaced a whole link with a half link from Charlie the Bikemonger. It solved all my problems.Posted 7 years ago
