Bike Spoke Adjustment Wrench Bicycle Rim Truing Tool Set of 2

Great tool , good price , fast shipping

Bargain spoke wrench. Simple, straightforward tool. Perfect to toss in your pack for on the go repairs/adjustments. Since it's stamped out of metal, it should last a lifetime.

What 'size' spoke wrench?: (Not easy to find one that fits!)My Vivi 26" ebike needed some spoke maintenance and I measured the steel spoke diameters as 2.23 to 2.27mm which came close to the 2.3mm 13 Gauge steel spoke type. So, it seemed to be a no-brainer to order a 13G Spoke Wrench. A check of the Vivi parts web page confirmed that both wheels use 13G spokes (longer length for the front wheel). Simple task .... just search Amazon for 13G Spoke wrenches! The search gave a bewildering array of misses and near-misses with a lot of reading to try to find the correct size. Fast forward through 3 months of iterations and multiple wrench buys and I ended up with the set of two: LETUSPORT Bike Spoke Adjustment Wrench which fit the best.Performance of the Red Circular Wrench:This wrench is described as ‘14Model’: Tightening 36 spokes on each wheel is painful. A tension of 130kgf is needed on the drive side of the Rear Motor-hub wheel! I ended up using this Vinyl Coated circular unit since it had a bit more leverage and felt more comfortable. The down side: This ‘14Model’ wrench is a bit loose for the Square-sided Spoke nipples and tended to round-out the nipples. The flat-to-flat measured Vivi 13G spoke nipple square diameter ranged from 3.60 to 3.63mm (new and not rounded). The mating opening of the wrench was 3.69 to 3.71mm which confirmed the loose fit. This wrench held up well after tightening several hundred nipples.Performance of the Multi-Size Circular Spoke Wrench (8slot heavy metal):The wrench as 3-sided square slots labeled: 10 (largest gap),11,12,13,14 and 15 (Smallest Gap). The 13 slot apparently does not correspond to a 13Gage spoke nipple; it was quite loose. The slot measured 3.94mm (vs 3.62 for the Nipple). The wrench has two ‘14’ slots which were not used initially, since the fit was very tight. Further inspection showed that one slot was only 3.56mm while the other measured 3.63 which was very snug. Dressing the wider ‘size14’ very lightly with a small file removed a few burrs, producing a smooth but snug fit.Recommendations:1. For initial, fast tightening of spokes, use the Red Wrench.2. For final tightening, switch to the size ‘14’ larger slot on the MultiSize Metal wrench. It will minimize spoke rounding at high torque settings but takes a bit longer for the snug fitting to the nipple.3. Add dry lube, linseed oil, or a suitable spoke lubricant for major jobs such as wheel rebuilding to make the job easier.Observations and more details:1. It appears that round steel spokes have varying nipple flat sizes. The Vivi 13gage spokes do not fit with the most popular wrenches (including the Park Tools SW6 Ehub Wrench which fits 3.7mm flats). The only wrench manufacturer that I found offers the correct specification wrench of “3.60mm/13G” is from IceToolz which is not available at Amazon.2. Consider dressing the the appropriate slot of your multislot wrench slightly if the fit is too tight.

Great tool anyone with a bicycle needs one

DOES THE JOB

the fit for the round spoke key is kinda jank, but it works... barely.3 stars because some of the slots are wee bit too narrow and some are wee bit too big.the 14mm key with the red rubber works fine though.

Did the job.

Excellent design easy to use
