Their just SRAM chain stay protectors I found on eBay for £3.99 if I remember correctly to stop the paint from getting damaged, I seemed to be marking those areas.
At one point they were the only ones I could get my hands on haha! Luckily I dont feel any differences! And the 2.8 rear feels great on the front :LOL:
New to the forum, here's a photo of my 2020 Whyte E150S almost 2000 miles in, few upgrades been purchased and now waiting on a Hope Fortus 30 rear wheel.
