Racing Line Carbon 2-Bolt Small

Product code: 12289

Super light booster!
86-97mm spacing.

- Ultra lightweight 2-bolt brake booster from Racing Line.
- Compatible with brake mount spacing ranging between 86mm and 97mm, meaning this booster is mostly suitable for use with a front brake, though it will also fit some frames / rear brakes. (Click here to see the Large version.)
- Offers 41mm vertical clearance from the top bolt hole.
- Black M5 titanium bolts with aluminium spacers and washers keep the weight as low as possible.
- Please note: these bolts are supplied in a length to suit washerless design clamps. If you're using brake clamps that require cylinder washers, you will need either bolts that are 5mm longer, or to cut down the spacers by 5mm.
- Washers must be used between the booster and bolt head.
- 3mm thick carbon fiber plate boasts 10 layers of carbon weave.
- Simple, constant-width, semi-circular design eliminates stress risers and looks elegant.
- Stylish printed graphics look great.
- Weight - Booster: 18.0g! Bolts, spacers and washers: 10.5g.

Works great!

This booster is on my 2015 Inspired Element fitted with Magura HS33 rim brakes. The supplied spacers only allow for a few mm's of thread engagement of the supplied bolts. I cut approx. 4 mm from the spacers and everything fit perfectly with good thread engagement. This is a very stiff booster. Prior to installation there was noticeable frame flex when the brakes were applied. Once installed, the flex all but disappeared. Very happy with this product.

Hi David - thank for the detailed review! We've just measured the bolts and spacers supplied with these clamps and they're primarily aimed at washerless design clamps. Brake clamps that use cylinder washers typically require around 5mm more thread contact ideally, so that would explain why they appeared to be so short for you bike (assuming you have something like the standard Magura clamps on there).
We're glad it's all up and running for you now though, and thanks again for the review.
