What size is a 7 speed chain?
What size is a 7 speed chain?
Symmetrical vs asymmetrical chains
| Chain no. of speeds | Outer width in mm |
|---|---|
| All 7-speed | 7.3 |
| All 8-speed | 7.1 |
| All 9-speed | 6.5 – 6.7 |
| 10-speed old Campagnolo | 6.2 |
Are 6 7 8 speed chains the same?
Chains for 6-, 7-, or 8-speed cassettes are generally universally compatible across brands and speeds. That means if a chain says “8-speed Shimano” you can use it in your old 6-speed, too. All you have to do is line up the new chain with the old one and cut it to size.
How is chain width measured?
It is measured by measuring the distance between 3 links, then dividing it by two.
- Chain pitch is shown with green markers, though it is determined by measuring the distance between 3 adjacent pins (blue mark) and dividing it by two.
- Inner chain width, marked with blue arrows and lines.
- From left to right:
How do you size a chain?
Determine the shortest length where a chain would connect inner and outer plates. From this point, count 4 rivets as the point to shorten the chain. This is an addition is 2 rivets (1-inch) more than non-dedicated 1X system.
Can I put a 8 speed cassette on a 7 speed hub?
7-speed hubs won’t normally accept 8-, 9- or 10 speed cassettes without modification. Click here for details. 7-speed cassettes fit fine on 8- and 9-speed (and most 10-speed) hubs if you put a 4.5 mm spacer onto the body before the cassette. Click here for details.
Can I put a 7 speed cassette on a 6 speed hub?
SP – WRONG! 6 and 7 speed have different spacing, 8 is slightly different to 7 as well. If the bike is from post 1989 or so it will have a block not a cassette, and a cassette won’t go on the hub. If it’s a 6 speed cassette it may have a threaded top cog meaning a modern 7 speed cassette won’t fit either.
How do you size a single speed chain?
Determining optimal single speed chain length Chain slack is about 1 cm to each side (up and down). So the chain should be tight, but not too tight. Halfway between chainrings, the chain should move about 2 cm (1 cm up-down).
What is the difference between 6 speed and 7 speed chain?
Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm. That is why the reverse is not the case and a 7 speed chain and especially a 6 speed one will not work as well on an 8 speed system. Of others, 9 speed chain can work. It is a bit narrower than optimal, but it can be used.
What is the standard size of a multi speed chain?
Multi speed chains, from 5 to 8 have inner width of 3/32″ (2.38 mm). Multi speed chains from 9 to 12 speeds have inner width of 11/128″ (2.18 mm). “Exotic” standard for freight bicycles is 5/32″ (4 mm).
What is the standard size of a chainsaw chain?
For inner chain width there are the following standard dimensions: Single speed chains have inner width of 1/8″ (3.175 mm). Multi speed chains, from 5 to 8 have inner width of 3/32″ (2.38 mm). Multi speed chains from 9 to 12 speeds have inner width of 11/128″ (2.18 mm).
What size chain do I need for my bike?
Since single speed chain is by far the cheapest, there is no need to experiment with multi speed chains. However, 6 to 8 speed chains can fit some single speed bicycles – depending on the chainring width. 5, 6, 7 and 8 speed chains 7.1 mm wide 8 speed chainwill fit all the other systems (5, 6 and 7 speed ones).
