With cycling season coming up (days getting longer, warmer etc), I thought this was too good a deal to go past. I've been looking at buying one of these from 1-day's sister site, Torpedo 7 for a while and very nearly did when they went on sale last week at $59.99.
Luckily, I hadn't bought one yet - because today, as part of 1-day's cycling sale, they're 55% off the regular price. Aside from the fact that Torpedo7 are generally cheaper than a lot of other cycling retailers anyway, this price was too good to pass up for me. Elsewhere, similar products can cost up to $200.
There are also some other good buys in the sale, so feel free to add to this post in the comments. Giyo pumps from $12.99 are hard to go past for their quality too, but it's worth checking the T7 site to check their regular price.
There's $12 shipping as well.
