This is the top of the line bike from Mongoose for 2018, and it’s by far the best L100 yet. The frame has been improved, now with 100% 4130 cromoly construction including removable brake hardware – a generous size for all, with 75 degree head angle, 11.5″ BB height, 13.75 back end, midsize BB, full cromoly fork and bar, and a new topload stem.
The cranks are 2pc cromoly, with full sealed mid BB and PC pedals – sealed wheels, 9T cassette with a cromoly driver, wide rims, 2.3″ tyres front and rear, and more… considering that this bike sells for less than around £349, this is all good news – finished with matt black paint and grey parts, you can’t go wrong.
