Help! Searching for an RST thru axle

Hello everyone,

In my ongoing quest to do more of my own maintenance I've managed to pretty much thread the hex socket on my front thru axle. (Yay for learning experiences!) I must have failed to fully inserted the torque wrench on a few previous installs and now it's tricky to get purchase on socket.

I took it into my LBS and neither they nor Giant Australia stock replacements. (Horray for the support of big three networks!) Giant is trying to source one from overseas but they've given me no timeframe or even certainty they can do so. RST Global have not answered my web queries. So I'm trying to track down a replacement myself.

The thru axle comes with my RST Vivair E shocks. Specs on the thru axle are scant. The UK Giant site gave me the most info, listing a '15x100' axle. I'm loathe to attempt to take it off to measure as a) everything is working just fine for the time being, and b) I may not be able to put it back on again! If I find a replacement I'll probably take it in to the LBS and get them to swap axles when I get my next service.

Possibly compatible products include:
RST Thru Axle
Brand-X Bolt Thru Axle in 100-148-11-M15 size

Both these are quick release, which suits me just fine if they fit

Wolf Tooth axle bit $$$y
Rockshox SRAM Mahle I'm not even sure this is compatible

Can any shock experts here shed some light? Cheers!

Measuring your existing axle would be the best approach, though I understand your reluctance.

The Robert Axle Project at https://robertaxleproject.com/axle-finder-2/ might be able to help. Select Wheel Only - Front in their axle finder, answer the rest of of he questions, and they'll list their products that will fit.

Good luck.

Thanks @Sierratim! The finder led me to an axle similar to what I linked, so looks like I was on the right track. I'll take it off and do a proper measurement before ordering anything. Now if only their price and shipping was a little more affordable for our battered exchange rate!
 
Oooooookay, Giant Australia has been absolutely useless at ordering me a spare thru axle. However I got somewhere via email with RST in Taiwan. I now have dimensions for my Vivair E thru bolt - see image below. I hope I'm interpreting that correctly as: M15 x 1.5 x 122. I'm not sure of the thread pitch but guessing 1.5.

Robert Axle has a M15 x 1.5 x 125 (https://www.abbotsfordcycles.com.au/lightning-bolt-on-axle-front-15mm-m15-x-15-125mm_p4467). Will that fit?

The Robert Axle Project has great customer service, esp when you have a drawing of what you need! I suggest you send that to them and ask them to match it.

You're right, their customer service is exceptional! I have the nearest size on order. It's a few mm longer than my current bolt but we'll see how we go.

I swear - it often seems the quality of customer service is directly inverse to the purchase price.. :rolleyes:
