Topstone 1 Gravel Bike - BlackThe Topstone 1 sits atop of the range of alloy bikes and comes equipped with a 12 speed Shimano GRX 820 600 groupset.

The Shimano GRX 600 400 hydraulic disc brakes pack plenty of power and perform no matter the conditions. 37c WTB Riddler TCS tyres offer a great balance of grip and low rolling resistance, so they won't hold you back on the tarmac but they still hook up on rough

The Topstone 1 sits atop of the range of alloy bikes and comes equipped with a 12-speed Shimano GRX 820/600 groupset. This is a robust groupset designed for the rigours of off-road riding. The Shimano GRX 600/400 hydraulic disc brakes pack plenty of power and perform no matter the conditions. 37c WTB Riddler TCS tyres offer a great balance of grip and low rolling resistance, so they won't hold you back on the tarmac but they still hook up on rough corners. These are mounted on WTB ST i23 rims laced to dependable, sealed cartridge-bearing Formula hubs. Touch points are well thought out too, with a Fizik saddle and comfortable flared drop bars. With clearance for tyres up to 45mm, push your own limits from the road to gravel trails whilst maintaining grip and comfort as you ride. 

This spec choice gives top-end performance with crisp shifting, powerful braking and low weight. Combine this with the excellent alloy frame, you dodge the carbon price tag for an excellent value bike. The Topstone 1 can be a commuting workhorse, a winter training bike, or a gravel adventure machine. However you use your Topstone, it's guaranteed to deliver fun and excitement all the way from the start of your ride to the finish.

Features: 

  • Lightweight SmartFoam C2 Alloy frame with a full carbon fork
  • Exceptionally precise and refined shifting from Shimano's upper-tier mechanical GRX 820/600 2x12 speed gravel group
  • Superb power and modulation from Shimano's GRX 600/400 hydraulic disc brakes
  • Rugged, reliable WTB ST i23 TCS tubeless ready rims with Riddler 700x37c tyres
  • Long distance comfort from Fizik's Aliante Delta saddle
  • Clearance for big 45mm tyres to push onto rougher terrains and enjoy more grip and comfort
  • Easy mounting point for fenders
  • OutFront Steering Geometry: extra long fork offset paired with a slack head tube angle keeps the steering light and lively yet delivers confidence at speed or over rough terrains
  • Full carbon fork is light, comfortable and precise
  • Dropper ready: built to accept an internally-routed 27.2 dropper seatpost

Engine Air Filter
Size: (Pack of 1)
This engine air filter fit perfectly in my 2018 Honda CR-V. No idea how it will perform but so far the Check Engine Light has not come on since installing the filter. Since there have been no problems I am happy with this filter and will likely buy again in the future. The filter does appear to be made from quality materials.

My mileage on my 2021 Honda CRV dropped 4 miles /gallon with this air filter.
Size: (Pack of 1)
My mileage on my 2021 Honda CRV dropped 4 miles /gallon with this air filter. It did fit well and was easy to install, but then I watched my average around town mileage drop from 29-31mpg to 26-27 mpg thru 2 tank fillups. The Honda repair person said this filter looked like the Honda one and was surprised when we wanted to switch it out. Granted, it looked just like the Honda filter, but the folds on the Honda one are yellowish and I have to think there has to be some difference in the texture. The average mileage went back up within 10 miles of replacing it and 3 fill ups later it has continuously maintained its original average of 29-31 with the Honda filter.

As good as Original Manufacturer Equipment.
Size: (Pack of 1)
Cheaper than having the dealer or oil change store do it. Only takes a minute to replace your existing filter for a lot less than what they want to charge you. High quality too!

Excellent Honda Alternative
Size: (Pack of 1)
I try to get everything and to keep everything as a manufacturer original on a car as possible. I will say that this filter is just as good as the Honda. The installation was very simple, you just need a screw driver to unscrew the 4 screws in the air box and this sits right in. The engine ran better and immediately got so much better MPG. I did not notice the engine struggling for air at all, if anything the car ran better. The fitment was the same size and just as good as the Honda. P.S Don't be like me. Don't hesitate to buy it. You'll love it. No questions asked!
