Chain tensioner for bicycle engine

Chain tensioner for a bicycle engine: the photo shows a zinc-plated plate with a white wheel and bolts, no dimensions marked in the photo.

• Honestly: the manufacturer did not write a single number on this listing's photos. Everything we write is what the photo shows
• The first photo – a plate with the wheel and a hex bolt; the bolt head shows a stamped marking
• The second photo shows the whole set: a bent clamp with three nuts and a separate white grooved wheel
• The groove in the wheel keeps the chain from slipping sideways
• Chain tension is checked at the middle of its swing: healthy tension lets the chain move about a finger's width up and down, not sit as taut as a guitar string
• Time to replace it when the thread is stripped, when the hole in the plate has widened, or when the bolt no longer holds its set position
• Supplier code WI AWRC7005 — state it again when ordering

To be straight with you: the manufacturer did not state the wheel's diameter or the clamp's width — there are no dimensions in the photo. Which exact model and which years this part fits, the manufacturer did not state, and we do not guess — but we can compare dimensions for you: write us your model and year. Before ordering, measure your frame tube at the spot where you will fit the clamp — or send a photo: we will check before you order.
